The Lovato P5ME4PS0800 is a high-performance four-pole moulded case circuit breaker (MCCB) designed to provide reliable overload and short-circuit protection for demanding industrial and commercial low-voltage distribution systems. As part of the Lovato P5ME moulded case circuit breaker series, it combines an 800 A rated current with an electronic trip unit and adjustable protection settings for accurate circuit protection and improved coordination.
The P5ME4PS0800 provides an electronic overload trip adjustment range of 320–800 A together with an electronic short-circuit trip adjustment range of 480–8000 A. Its four-pole IEC configuration, with the fourth pole positioned on the left side, enables simultaneous switching and protection of four conductors in suitable three-phase distribution systems.
With an ultimate short-circuit breaking capacity Icu of 65 kA at 380–415 V AC and a rated operational voltage up to 690 V AC, the P5ME4PS0800 provides substantial fault-interruption capability for high-current installations. Its robust screw-mounted construction and comprehensive P5 accessory platform make it suitable for main distribution boards, industrial switchboards, machinery supplies and other demanding power distribution applications.
Moulded case circuit breakers such as the Lovato P5ME4PS0800 protect electrical installations against damaging overload and short-circuit currents. Its electronic trip unit monitors circuit current and disconnects the supply when operating conditions exceed the configured protection thresholds, helping protect conductors, switchgear and connected equipment.
The wide adjustment ranges of the P5ME4PS0800 allow overload and short-circuit protection to be coordinated with the requirements of high-current distribution circuits. Combined with its four-pole construction, high breaking capacity and 690 V AC operational rating, the breaker is well suited to industrial power systems requiring configurable protection and dependable fault interruption.
