The MB3303AS residual current protection module is a functional module that integrates a type B residual current detection unit and a micro-processing unit. It can be used for type B residual current action circuit breaker. When the action threshold set by the module is reached, the module will output a tripping signal. The user can introduce this signal into the tripping device to achieve tripping protection.
