Schneider Electric LV540318 EasyPact CVS400N 4P 320 A 50 kA TM-D Fixed Moulded Case Circuit Breaker
Schneider Electric CVS400N TM-D thermal-magnetic MCCB, 320 A, 50 kA Icu, distribution protection.
Description
About the CVS400N
About the CVS400N
The Schneider Electric LV540318 is a 4-pole EasyPact CVS400N moulded case circuit breaker rated 320 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 224...320 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.
