RDX2LE-125 molded case circuit breaker (hereinafter referred to as circuit breaker) is a current-limiting molded case circuit breaker with dual protection of overload and short circuit. The circuit breaker is suitable for circuits with AC 50Hz or 60Hz, rated working voltage up to 230V/400V, and rated current up to 125A. It is used as overload and short circuit protection for the line, and can also be used for infrequent connection and disconnection of electrical devices and lighting circuits.

Features :
Residual current (leakage) protection, residual current gear can be adjusted online, and delayed and non-delayed types can be selected at will;
●with primary reclosing function;
● Automatic tracking, automatic adjustment of the gear according to the residual current of the line, ensuring the commissioning rate and reliability of the product;
●Long-delay, short-delay and instantaneous three-stage protection, current can be set, with electronic decoupling, independent of power supply voltage;
●High breaking capacity to ensure the reliability of line short circuit protection;
● High-current instantaneous decoupling function, when the circuit breaker is closed and encounters a short-circuit high current (≥20Inm), the circuit breaker is directly decoupled by
electromagnetic decoupler mechanism is directly decoupled;
● Over-voltage protection, under-voltage protection, phase failure protection;
● Leakage non-disconnecting alarm output function;
