Schneider EasyPact CVS160B LV516303 160A 3P3D MCCB – 25kA at 415V, TM‑D 160A Trip Unit, IEC 60947‑2

Schneider Electric EasyPact CVS LV516303 is a three‑pole moulded case circuit breaker from the CVS160B frame, designed for protection and switching of low‑voltage distribution circuits in small and medium‑sized buildings and industrial panels. It has a 160A rated current at 40°C and uses a TM‑D thermal‑magnetic trip unit (TM160D), with adjustable long‑time (overload) protection and fixed magnetic (short‑circuit) protection. The breaker’s rated ultimate breaking capacity Icu is 25kA at 400/415V AC, with higher values (up to about 40kA) at 220/240V, complying with IEC 60947‑2, so it can safely interrupt high prospective fault currents on feeders and main incomers. This model is configured as 3P/3D, meaning three poles, all three protected and switched, for three‑phase systems without neutral. It is a fixed‑type device with front terminals and toggle operation, offering isolation, overload and short‑circuit protection in one compact unit. Typical ratings include Ue up to 440V AC, Ui 690V, Uimp 8kV and utilisation category A. The EasyPact CVS range supports accessories such as rotary handles, shunt and undervoltage releases and auxiliary contacts, allowing flexible integration into switchboards.
