It operates on a 200-250 V AC 50/60 Hz or 200-250 V DC control circuit, with a threshold tripping voltage of 0.85 to 1.1 times the nominal control voltage (Un). The drawout mounting mode means this coil is not a panel-mount standalone device — it plugs into the MasterPact MTZ breaker's drawout cassette. If your breaker is a fixed-mount MTZ, this coil will not fit without the drawout cradle. The response time varies by frame size: 55 ms ±10% for MTZ1, 70 ms ±10% for MTZ2, and 80 ms ±10% for MTZ3. That timing matters if your control scheme sequences multiple breakers and needs coordinated closing delays. Holding power is rated at 4.5 VA (AC) or 4.5 W (DC) — a light continuous load on the control transformer, but verify the control circuit's minimum load rating if you are switching it through a PLC output card. The Device Application is listed as Control, meaning it is intended for closing the breaker under command, not for protection tripping.","metaTitle":"Schneider LV839257 XF Closing Coil, 200-250V AC/DC, for MTZ","metaDescription":"Schneider LV839257 XF closing voltage release for MasterPact MTZ drawout. 200-250V AC/DC control circuit.
