Schneider Electric LV510451 EasyPact CVS100N 3P 6.3 A 50 kA MA Fixed Moulded Case Circuit Breaker

The Schneider Electric LV510451 is a 3-pole EasyPact CVS100N moulded case circuit breaker rated 6.3 A, with a breaking capacity of 50 kA at 380/415 V AC. It uses an MA magnetic-only trip unit for motor-circuit short-circuit protection, with the instantaneous pick-up adjustable from 6 to 14 times In, and mounts as a fixed, backplate-mounted device.

Selection Notes

The MA magnetic-only trip unit on the LV510451 provides short-circuit protection only, with the instantaneous pick-up adjustable from 6 to 14 times the 6.3 A rating — there is no thermal overload stage, so a separate motor overload relay or thermal device is required for full motor protection. This N-code frame is rated 50 kA at 380/415 V AC, the highest breaking capacity available in this CVS100 MA line; choose the F-code (36 kA) version where fault levels are lower. Within the EasyPact CVS100N MA range, pick the current rating that places the motor's locked-rotor current inside the breaker's instantaneous adjustment window.
