functions These electrical auxiliaries are used forremote indication or tr ipping of the residualcurrent circuit breakers.

description

remote trippingAn MX or MN release can be used for thispurpose.Tripping is shown by a red indicator on thefront face.

MX + OF shunt trip releasetrips and opens its associated circuit-breakerwhen energised:c equipped with a self-breaking switchc equipped with a switch (terminals 12and 14) to indicate whether the circuit-breaker is "open" or "closed" when the coil isenergised.

MN undervoltage releasetrips and opens its associated circuit-breakerwhen the supply voltage drops (between 70and 35%) and prevents reclosing until thesupply voltage is restored:c complies with standards IEC 6947-2c use:v push button emergency stopv safety on the supply circuits of severalmachines by disabling "uncontrolled" restartof all motors.

MN time delayed undervoltage release sThis undervoltage release controls theopening of its associated residual currentswitch. It allows a 0.2 second time delay onshort supply interruptions or voltage drops
