JXM3L series residual current operated circuit breakerDetailed product description：

Product usage and scope of application:
The JXM3L series residual current operated circuit breaker is suitable for use in low-voltage power grids with AC 50HZ, rated current up to 800A, and rated working voltage of 400V and below. It is used for personal electric shock and equipment leakage protection, and can also prevent fire hazards caused by grounding fault currents due to equipment insulation damage. And it can be used to protect against overload and short circuit of motors and circuits, and can also be used for infrequent starting or switching of motors and circuits

·Function and purpose:
The JXM3L series residual current operated circuit breaker has functions of personal electric shock and equipment leakage protection, overload and short circuit protection. It is used to prevent fire hazards caused by grounding fault currents due to equipment insulation damage. It can also be used for distribution protection, infrequent line switching, and motor starting protection. The derivative product of this series, the leakage alarm circuit breaker, has the general function of a circuit breaker. When the leakage current of the line reaches the specified value, it outputs a set of contact signals (acting as an alarm) without tripping the circuit breaker.
·Rated current of shell level: 63A, 100A, 200A, 400A, 800A.
·Rated working voltage: AC 400V and below.
·Rated insulation voltage: AC 500V.
·Rated residual operating current: 30mA, 100mA, 300mA, 500mA, 1000mA (available for general and adjustable types respectively).
·Rated residual current action time: general type, delayed type.
·Release form: electronic leakage release, electromagnetic thermal type.
·The attachments include undervoltage, shunt excitation, auxiliary, alarm, etc. Modular installation of accessories for circuit breakers above 400A, allowing users to install without opening the circuit breaker body; The combination forms are diverse and can fully meet the needs of users.
·There are various installation methods, including front board, back board, insertion, and extraction.
