          Schneider Undervoltage & Shunt Releases

          Rubicon Industrial Technology is an authorised Schneider Electric distributor in South Africa. An undervoltage release (MN) trips a circuit breaker when the supply voltage drops; a shunt release (MX) trips it from a remote signal such as an emergency stop. This page lists both for Schneider breakers.

          ComPact NSX MN undervoltage releases from 12 V DC to 480 V AC and ComPact NSX MX shunt releases from 12 V DC to 415 V AC. Acti9 iMN undervoltage releases and Acti9 shunt trip releases, some with an OC contact, for miniature circuit breakers. Shunt releases for TeSys motor circuit breakers. Each title states the coil voltage, which is how a release is chosen.

          For the breakers themselves see Schneider circuit breakers, and for the rest of the range all Schneider Electric products.
