Frequently Asked Questions(FAQ)
Q: What is the application of the DZ47-63 MCB?
A: The DZ47-63 MCB is primarily used in AC 50/60Hz terminal distribution systems for overload and short-circuit protection in residential and office lighting circuits.
Q: Can DZ47 be used as a main switch?
A: It depends on the application environment and load requirements:
For Residential Use: A 2P (Two-Pole) DZ47 MCB is commonly used as a main switch for household distribution boxes, providing reliable protection for single-phase circuits.
For Industrial/Commercial Use: We recommend using 3P or 4P configurations for three-phase systems. For heavy-duty industrial incoming protection requiring higher breaking capacities and adjustable tripping settings, we highly recommend our SWM1 MCCB series as the primary main switch to ensure maximum system safety.
Q: What is the lifespan of SINGI DZ47 MCB?
A: It supports over 10,000 mechanical operations , ensuring years of reliable service.

Application Scenario
1.Residential and Commercial Buildings
Residential Electrical Protection: In ordinary residential houses, MCBs are used to protect circuits for lighting, sockets, air conditioners, water heaters, and other appliances. If a short circuit or overload occurs in an appliance, the MCB can shuts off the power quickly , preventing overheating and fires from wires, ensuring the safety of people and property.
Commercial Space Protection: In commercial space like office building, shopping mall, and hotel, MCBs are used to protect circuits for various office equipment, lighting systems, and air conditioning systems. The MCBs can prevent circuit overloads and short circuits quickly which is caused by equipment failure or human error, ensuring the safety of people and property.
2.Industrial Sector
Small Equipment Protection: In industrial production, many small equipment and machinery require MCBs for circuit protection. For example, small machine tools and power tools require MCBs to prevent damage from abnormal current flow during operation, extending their service life.
Control Circuit Protection: In complex industrial control systems, MCBs are used to protect the normal operation of control circuits. They ensure that power is promptly cut off in the event of a fault, preventing damage to the control system and thus ensuring the stability and safety of the entire industrial process.
3.Lighting Systems
Public Lighting: In public lighting spaces like street lighting, square lighting, and park lighting, MCBs are used to protect lighting circuits. MCBs can prevent short circuits and overloads which is caused by lamp failures or aging wiring, ensuring the reliability of the lamps and providing a safe nighttime environment.
Large Indoor Lighting: MCBs also is important in the indoor lighting systems of large buildings, like shopping malls, stadiums, and exhibition halls. They protect lighting circuits stably, preventing electrical failures that can occur due to a large number of lamps and complex wiring, and ensuring the normal operation of indoor lighting.
4. Low-Voltage Power Distribution System
Core Component of Distribution Boxes: In low-voltage power distribution systems, MCBs are standard features in distribution boxes and cabinets. They provide independent protection and control for each branch circuit and can be flexibly configured based on actual power load. They are key to achieving intelligent power distribution management and comprehensive system protection.
A safety benchmark for temporary power use: Construction sites, outdoor activities, and other temporary power-using environments present complex electrical environments and numerous potential safety hazards. MCBs provide essential safety protection for these temporary equipment and lines, ensuring proper operation even in these complex power-using environments and minimizing electrical safety incidents.
Purchase Plan
How to choose household small circuit breaker and leakageswitch when the new house is decorated?
Answer: Modern household electricity should be divided in accordance with open circuit, power outletcircuit, air conditioning circuit, separate wiring. When one of the circuits such as socket circuit fault, othercircuits can still supply power normally. Socket circuit should install leakage protection device to preventpersonal electric shock accident caused by leakage of electric current in household appliances.1.Main switch of household distribution box: should choose 32A-63A miniature circuit breaker which candisconnect both phase line and neutral line is generally selected.2.Lighting circuit: small circuit breaker with general choice of 10A-16A.3.Socket circuit: small circuit breaker with general choice of 16A-20A.4.Air conditioning circuit of 1: 1-1. 2 HP of air conditioning circuit generally choose small circuit breaker of16-25A. Three to five HP require 25A-32A small circuit breakers and central air conditioners withindependent 2P40A or so small circuit breakers.5.For bipole or 1PN circuit breakers, when a short circuit or a leakage fault occurs, the phase and neutrallines of the power supply will cut off to ensure personal safety and the completeness of the electricalequipment.
Note: the above selection is for reference only, and the actual electrical power of each household isdifferent. The specific selection shall be in accordance with the electrical design.
How to calculate and select the air switch according to thepower of home appliance?
1horse power=735W≈750W; 1.5horse power=1.5x750W=1125W; 2horse power=2x750W=1500W;2.5horse power=2.5x750W=1875W Calculation method and so on.Example one: How many ampere air switches should be selected for 3 horse conditioners? (220V voltage)3X750W=2250WX3 (Impulse current) =6750W-220V=30.68A≈32AExample two: How many ampere air switches should be selected for 5 horse power air conditioning?(380V voltage)5x750W=3750Wx3 (Impulse current) 11250W. +380V=29.6 A≈32A.(Power + Voltage =Amp)Note: the average operating life of the air switch under rated load is 20000 times. In the case of knowingthe leakage switch and air switch, in general, in the process of selecting distribution box for the customer,the light should be small and the socket should be in. According to the requirements of customers andthe difference of decoration personality, combined with the actual situation to carry out flexible distribution scheme.
Circuit Breaker knowledge
1. What is a miniature circuit breaker?Can turn on, load, and break current under normal circuit conditions. Under the extraordinary condition(such as short-circuit current), a mechanical switching device that can also turn on, carry a certain amountof time, and break the current.
2. What is the meaning of 1P, 2P, 3P and 4P on an air circuit breaker? Are there any differences betweenthem? How should they be used?
1P is also called pole. There is only one terminal and only one phase wire can be disconnected. This typeof switch is suitable for controlling a phase "fire" wire;2P is also called bipolar or bipolar. There are two wiring terminals, one phase connection and one zero connection. This switch is suitable for controlling one phase and one zero.3P is also called three-pole, there are three wiring terminals, three are connected to the "ire" line, this switch is suitable for controlling three-phase 380V voltage line;4P is also called quadrupole. There are two wiring lugs, three "fire" wires, and one zero wire. This switchis suitable for controlling three-phase four-wire lines
3.In terms of circuit breakers, what is the difference between 2P and 1P + N empty switch? What do theymean?P stands for the number of poles, Neutral stands for the zero line, 2P sign miniature circuit breakers bothhave thermal magnetic protection function, the width is 36mm; and 1P+Neutral pole, only the hot wiremagnetic protection function, N pole does not have the wire magnetic protection function, but willDisconnected at the same time as the line of fire, the width is 18mm. Therefore, 1P+N is more economicalthan 2P, and also has higher security, and is suitable for applications where lighting circuits are less current.
