It's the part that translates a remote close command into mechanical action inside the MTZ1, MTZ2, or MTZ3 frame. Control voltage is 12 V DC — that's the coil supply, not the main power circuit. The threshold tripping voltage range of 0.85...1.1 Un means the coil will reliably pick up at 10.2 V DC and stay held up to 13.2 V DC, which gives you some margin on a sagging 12 V bus. Response time varies by frame: 55 ms ± 10% on the MTZ1, 70 ms on the MTZ2, 80 ms on the MTZ3. That's the delay from energizing the coil to the breaker contacts closing — relevant if you're sequencing multiple breakers in a transfer scheme and need to coordinate timing. The 'Communicating' control type means this release talks to the breaker's control unit — it's not a dumb solenoid. The signalling function includes electrical push-button activated status, ready-to-close indication, and coil-powered error reporting, so the panel PLC knows what the release is doing. ## Deployment context This is a drawout-mounted accessory for MasterPact MTZ air circuit breakers — it slides into the chassis, not onto a DIN rail. The drawout form factor means it's swapped without rewiring the main power cables, which matters in switchgear where downtime for a coil swap needs to be minutes, not hours.","metaTitle":"LV839246 XF com Closing Voltage Release, 12 V DC, Obsolete","metaDescription":"LV839246 XF communicating closing voltage release for MasterPact MTZ drawout breakers. 12 V DC control, 55-80 ms response.
