It operates on a 12 V DC control circuit and triggers the breaker trip when the control voltage drops to between 0.7 and 1.1 times the rated Un. Response time is 50 ms ± 10% across MTZ1, MTZ2, and MTZ3 frames — consistent enough for coordinated protection schemes where the opening coil must clear before downstream devices. The drawout mounting means this coil is intended for the removable chassis of a MasterPact MTZ breaker — it is not a fixed-mount accessory. The 12 V DC control voltage is the nominal coil supply; the tripping threshold of 0.7 to 1.1 Un means the coil will release the breaker when the control voltage falls to roughly 8.4 V DC or rises to 13.2 V DC, providing undervoltage protection. The holding power of 4.5 VA / 4.5 W is the steady-state draw once the coil is energized — relevant for sizing the control transformer or DC supply feeding the trip circuit. ## Deployment context This coil mounts into the drawout cradle of a MasterPact MTZ air circuit breaker — common in main switchboards, generator paralleling gear, and large motor control centers where the breaker must be removable for maintenance without disturbing line-side connections. The MX communication variant allows the trip signal to be initiated remotely via the breaker's communication network, which is typical in automated power distribution systems.","metaTitle":"LV839225 MX communicating opening coil, 12 V DC, for MTZ dra","metaDescription":"LV839225 MX communicating opening voltage release, 12 V DC, for MasterPact MTZ drawout.
