It energizes the breaker's closing mechanism when the control voltage is applied, allowing remote or automatic closing of the main contacts. Control circuit voltage is 48 V AC at 50/60 Hz or 48 to 60 V DC, with a threshold tripping voltage range of 0.85 to 1.1 times the nominal voltage (Un). Holding power draws 4.5 VA (AC) or 4.5 W (DC). Response time is frame-dependent: 55 ms ±10% on MTZ1, 70 ms ±10% on MTZ2, and 80 ms ±10% on MTZ3. The drawout mounting mode means this coil installs into the breaker's drawout cradle, not the fixed portion — relevant when specifying spare parts for a drawout chassis. The 48 V AC / 48-60 V DC control voltage is the critical fit parameter — this coil will not operate on 24 V or 110 V control power. The 0.85 to 1.1 Un threshold means the coil picks up reliably at 40.8 V AC (0.85 × 48 V) and must not see sustained voltage above 52.8 V AC (1.1 × 48 V). On the DC side, the acceptable range is 40.8 V to 66 V DC. Holding power of 4.5 VA / 4.5 W is modest — the control transformer or DC supply only needs to support that continuous draw once the coil is sealed. The inrush is higher but brief; the response time figures (55-80 ms) include the mechanical travel of the closing mechanism.","metaTitle":"Schneider Electric LV839255 XF closing coil, 48 V AC/DC, for","metaDescription":"Schneider Electric LV839255 XF closing voltage release for MasterPact MTZ drawout breakers. 48 V AC 50/60 Hz / 48-60 V DC control circuit.
