Global Leaders of Actuator Technology

Mag-Latch Permanent Magnetic Actuators

TheMag-Latch is a critical and reliable component of many successful Medium Voltage Switchgear products. The performance of the ML repeatedly outclasses the traditional spring mechanisms. The mechanism contains few parts which enables a rapid and accurate assembly of a circuit breaker. The ML is designed for 100,000 operations making it a low maintenance product.
EPS manufactures a standard range of ML actuators varying in size and hold force (N).

The Mag-Latch actuator can be customised to meet the needs of a specific client. We have worked with many switchgear manufacturers to modify the Mag-Latch to suit the design requirements of our clients. Typically, we are able to customise stroke length, hold force application-specific output shaft, hand trip mechanisms, indicators, counters, auxiliary switches, speed, force and travel characteristics.

The Mag-Latch magnetic actuators are used in a variety of cutting-edge circuit breakers worldwide:
- ABB's VM1, AMVAC, R-MAG & FSK.
- Thomas & Bett's MVS.
- EGIC's VSV.
- Cooper Power's NOVA.
- P&B Switchgear's VOR-M.
