  • Description

The Schneider Electric LV540319 is a 4-pole EasyPact CVS400N moulded case circuit breaker rated 400 A with a 50 kA breaking capacity (Icu) at 380/415 V AC. It uses a TM-D thermal-magnetic trip unit combining adjustable thermal overload with magnetic short-circuit protection for general distribution feeders. The breaker is fixed-mounted and carries IP40 front-face ingress protection.

Selection Notes

The TM-D trip unit pairs an adjustable thermal overload element (Ir 0.7...1x In, thermal protection adjustment range 280...400 A) with a magnetic trip (5...10x In) in one device, so this CVS400N covers both overload and short-circuit duty without a separate relay - the configuration to pick over the MA (magnetic-only) version of the same frame when no downstream overload device is installed. Its 50 kA Icu at 380/415 V AC sets the fault-current ceiling for this breaking-code-N frame; move to a higher breaking-code letter if prospective fault current exceeds that rating.
