Schneider Electric LV510311 EasyPact CVS100B 4P 25 A 25 kA TM-D Fixed Moulded Case Circuit Breaker

The Schneider Electric LV510311 is a 4-pole EasyPact CVS100B moulded case circuit breaker rated 25 A, with a breaking capacity of 25 kA at 380/415 V AC. It uses a TM-D thermal-magnetic trip unit, combining adjustable thermal overload protection with a fixed magnetic short-circuit trip, and mounts as a fixed, backplate-mounted device for distribution applications up to 25 A.

Selection Notes

The TM-D trip unit on the LV510311 pairs an adjustable thermal overload stage (17.5–25 A) with a fixed magnetic instantaneous trip at 300 A, so the overload threshold can be tuned to the connected load while the short-circuit threshold stays fixed. The 4-pole version adds a protected neutral pole. In the CVS100B frame, 25 kA at 380/415 V AC covers general distribution circuits with moderate fault levels; move to the CVS100F (36 kA) code if the prospective fault current at the installation point is higher.
