Why Choose the Lovato P5ME4PS0400 Moulded Case Circuit Breaker?
The Lovato P5ME4PS0400 is a high-performance 4-pole moulded case circuit breaker (MCCB) designed for protection and isolation of high-current low-voltage electrical distribution systems. As part of the Lovato P5 series, this IEC circuit breaker combines a 400 A rated current with electronic protection for dependable operation in demanding industrial installations.
Its four-pole configuration enables simultaneous switching and protection of three phase conductors and the neutral, making the P5ME4PS0400 particularly suitable for three-phase, four-wire distribution networks. The electronic trip system provides overload and short-circuit protection while allowing the breaker to be coordinated with the requirements of the protected installation.
With an ultimate short-circuit breaking capacity Icu of 50 kA at 380–415 V AC, the P5ME4PS0400 is engineered for industrial switchboards, distribution panels and machinery power systems where substantial prospective fault currents may occur. Its moulded-case construction and compatibility with the Lovato P5 accessory system provide a flexible platform for professional panel building.
