After clipping on to NDM1 series MCB,
Point 91 and 92 are connected when circuit is closed;
Point 91 and 94 are connected when the breaker trips due to fault;
Point 91 and 92 are connected when the breaker trips by manual
operation. Meanwhile, point 91 and 94 are disconnected.
May be used in conjunction with a OF auxiliary switch or another
SD alarm switch.

Product Features
AC type: protection against the effects of residual

Working Condition
A type: protection against the effects of residual
sinusoidal alternating currents and residual pulsating
direct currents, whether suddenly applied or slowly rising.
Residual current operating function is independent of

Specifications
Besides detecting residual current, the product can
make, break or isolate the whole circuit without
overload or short-circuit protection, so it should be
used together with circuit breaker upstream.
