The Schneider LV848480 is a standard closing voltage release (XF type) for MasterPact MTZ2 and MTZ3 drawout circuit breakers. It operates on a 12 VDC supply with a holding power consumption of 4.5 W, and its closing threshold is 0.85 to 1.1 times the rated supply voltage (Un). This is the coil that pulls the breaker closed on command — not a shunt trip or undervoltage release.
The 12 VDC supply is the coil voltage — verify your control power matches before wiring. The 4.5 W holding power is steady-state after the coil seals in; the inrush (pickup) draw is higher but not listed here. The 0.85...1.1 Un closing threshold means the coil will reliably close the breaker when the supply voltage is between 10.2 V and 13.2 V DC. Below 10.2 V it may not pull in. The 80 ms (MTZ2) to 90 ms (MTZ3) closing response time is the mechanical stroke, not the electrical contact make — that's fast enough for standard control sequencing but not for arc-flash mitigation schemes that need sub-cycle closing.
Deployment Context
This coil mounts inside the MasterPact MTZ2 or MTZ3 drawout cassette — it's not a standalone panel component. The drawout mounting mode means the breaker chassis stays wired to the bus while the moving portion (with the coil installed) can be racked out for maintenance. If you're retrofitting an existing MTZ2/3 cradle, verify the coil connector pinout matches your cradle's control wiring; the drawout interface is keyed but different vintages may have changed the terminal arrangement.
