Schneider EasyPact CVS MCCB LV525303 – 250A, 3P3D, 25kA at 415V, TM250D Trip Unit, IEC 60947‑2

Schneider Electric EasyPact CVS MCCB LV525303 is a three‑pole moulded case circuit breaker from the CVS250B frame, designed for protection and control of low‑voltage distribution in commercial and industrial installations. It has a 250A rated current at 40°C and uses a TM250D thermal‑magnetic trip unit, with adjustable long‑time (overload) protection and fixed magnetic (short‑circuit) protection. The breaker offers a rated ultimate breaking capacity Icu of 25kA at 380/415V AC (and higher at lower voltages), conforming to IEC 60947‑2, making it suitable for feeders and main incomers with high prospective fault currents. This model is a 3P/3D configuration: three poles, all three protected and switching, for three‑phase systems without neutral. It is a fixed‑mounted device with Class II front insulation, toggle operation and front screw terminals, intended for mounting on a back‑plate inside panels or MCCB enclosures. The EasyPact CVS range provides good current‑limiting performance, clear contact‑position indication, and compatibility with a range of accessories such as rotary handles, shunt and undervoltage releases, and auxiliary contacts.
