Schneider Electric LV540305 EasyPact CVS400F 3P 320 A 36 kA TM-D Fixed Moulded Case Circuit Breaker
Schneider Electric CVS400F TM-D thermal-magnetic MCCB, 320 A, 36 kA Icu, distribution protection.
Description
About the CVS400F
About the CVS400F
The Schneider Electric LV540305 is a 3-pole EasyPact CVS400F moulded case circuit breaker rated 320 A with a 36 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 CVS400F 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 36 kA Icu at 380/415 V AC sets the fault-current ceiling for this breaking-code-F frame; move to a higher breaking-code letter if prospective fault current exceeds that rating.
