Product Features
1. Miniaturization design
Product volume miniaturization can meet the customer's personality needs of the product installation size.
2. Size uniform
The same shell level, different breaking capacity (S, M), different functions (air, leakage) product installation size is completely consistent.
3. The function of the reasonable parameter setting
Circuit breaker can realize long-time delay overload inverse time, short circuit instantaneous action protection functions such as parameter setting, users can set their own protective properties required, the distribution network is used in the circuit breaker on the lower level with more reasonable.

11. Work in the places where is no rain and snow.
MCCBs are essential protective devices for electrical power systems. They detect overloads and short circuits in the system and interrupt the flow of current to prevent damage to equipment and power outages. The key components of an MCCB include:
1. Contacts - Open or close circuits. Made of conductive material with high melting points like copper or copper alloys.
2. Arc chutes - Extinguish the arc when the contacts open. Often made of deionizing materials.
3. Bimetallic strips - sense overloads by bending in response to temperature increases from high current. They trigger the trip mechanism.
4. Solenoids - detect short circuits based on the strength of the magnetic field around the conductor. They activate the trip mechanism.
5. Trip mechanism - opens the contacts to interrupt the flow of current. Activated by the bimetallic strips or solenoids.
6. Housing - Encloses all components. Made of insulative and fire-retardant materials. Provides protection and anchoring.
The working environment and installation requirements for MCCBs mainly involve:
1. Ambient temperature control - MCCBs generate heat during operation, so the temperature around them should be regulated. Extreme heat can damage components.
2. Proper enclosure - MCCBs should be enclosed in electrical panels or cabinets to prevent environmental exposure.
3. Ventilation -Enclosures housing MCCBs require vents and fans to dissipate heat. Without cooling, MCCBs can overheat.
4. Secure mounting - MCCBs should be securely mounted to stable structures or panels to prevent disconnection of power lines or tripping hazards.
5. Accessibility - MCCBs should be installed in locations that allow for easy inspection, testing, and servicing. Hard to reach areas can hamper maintenance.
MCCBs have a proven record of safe, reliable and efficient operation. Strict manufacturing standards, intensive testing, and decades of innovation have resulted in robust, precision-engineered products that offer comprehensive protection to power systems across the world. Advances in MCCB technology have also made them more compact, adjustable, and environmentally friendly. Overall, MCCBs provide an invaluable service to homes and businesses alike.
