The MVAX relay supervises trip circuiting of circuit breakers and initiates audible alarms and visual indications if the trip circuit fails or the mechanism ceases to operate. 

The MVAX trip circuit supervision relays can be applied to monitor circuit breaker tripping circuits. They are compact in design and have a user-friendly interface. 

Optimum trip-circuit supervision
MVAX provides trip circuit supervision during breaker close or close and open. It avoids breaker mistripping by accidental short circuits and can ensure that no false alarms are indicated during protection operations.

User-friendly and flexible for maximum protection
Benefitting from a user-friendly interface and flexible operating logic, the MVAX relays are also compact and optimally designed. They ensure protection scheme integrity by closely supervising trip circuiting and signal alarms if mistripping occurs.
