The SWOM1L series plastic case circuit breaker with residual current protection adopts the form of a thermal magnetic release. This product has superior performance such as beautiful appearance, compact structure, long service life, low rated power consumption, stable performance, and convenient installation, providing users with safe and reliable protection.
This circuit breaker has isolation function.
With O and OFF position indication, the handle indicates the O and OFF positions when the contact is opened; The indicated position of the rotating handle or operating mechanism is consistent with the body, which will not affect the reliability of the product.
The circuit breaker can be installed vertically (i.e. vertically) or horizontally (i.e. horizontally).
With current limiting capability, the entire series is designed with a current limiting action mechanism, which extinguishes the arc before the expected short-circuit current reaches its peak, reliably suppressing the impact of short-circuit current on the circuit. The diagram shows the actual breaking short-circuit current peak and expected short-circuit current peak curve indicators of the current limiting action mechanism.

The SWOM1L series plastic case circuit breaker with residual current protection can achieve leakage protection function. The working power supply of the leakage protection module of the conventional residual current protection circuit breaker is sampled as two phases, and this series of leakage circuit breakers are three-phase. If any phase is missing, the leakage protection module of the circuit breaker can still operate normally;
2. On site adjustable: The rated residual operating current △ and residual current operating time (non delay and delay) can be adjusted on site according to the actual situation;
3. Low voltage protection: When the phase voltage drops to 50V, the leakage protection module can still operate normally:
4. With leakage alarm output function: When the residual current of the equipment or line reaches or exceeds the set value, the circuit breaker with leakage alarm unit module outputs a passive contact signal to drive the corresponding alarm device;
