The Schneider Electric LA11130 is an undervoltage release accessory for the PowerPact LA, LH, and Q4 circuit breaker frames. Rated for 250VDC, it is a trip unit accessory — not a standalone breaker — and mounts inside the breaker's accessory compartment.
The 250VDC rating governs the control voltage the release coil sees. It is not a breaker interrupting rating — the undervoltage release simply opens the breaker's trip mechanism when its coil voltage falls below the dropout threshold. Verify that your control circuit supplies 250VDC nominal; a 125VDC or 24VDC coil will not pull in on this variant. The accessory fits the PowerPact LA, LH, and Q4 frames only — not the smaller PowerPact B or J frames.
Deployment context
This part lives inside the breaker's accessory slot — no DIN-rail or panel space consumed beyond the breaker itself. Typical use is in motor control centers or distribution panels where undervoltage protection is specified to prevent automatic restart after a sag or outage.
