The SGB5L-63 A/B/AC type RCBO, supplied by Zhejiang Singi Electrical LLC,
is a 230/240 V AC device with a rated insulation voltage of 500 V and a rated impulse
withstand voltage of 4000 V. It features a shell frame current rating of up to 63 A and is available in
various rated currents ranging from 6 A to 63 A. The SGB5L-63 is designed to provide short-circuit,
overload, and residual current protection, with a rated residual operating current of 10 mA to 300 mA.
It has a rated residual making and breaking capacity of 3000 A and an ultimate breaking capacity of 10000 A.
The SGB5L-63 RCBO is available in A, B, and AC types. The B type is suitable for special applications that require
detection of pure direct current , such as photovoltaic systems and electric vehicle charging stations.
The A type is designed for environments where alternating current and pulsating DC fault currents need to be detected,
making it ideal for modern residential and commercial settings. The SGB5L-63 AC type RCBO is suitable for applications
that involve traditional AC fault currents.
