This release coil is designed for the immediate remote tripping of the MasterPact NT/NW circuit breaker. In combination with an XF energizing coil and an MCH motor drive, the MasterPact can be controlled remotely. The tripping occurs immediately via a working current. The immediate voltage release MX 100/130V AC/DC is for the MasterPact NT insert. This release coil can only be ordered in conjunction with a configured circuit breaker.
