Why Choose the Lovato P5ME3PS0250 Moulded Case Circuit Breaker?
The Lovato P5ME3PS0250 is a high-performance three-pole moulded case circuit breaker (MCCB) designed to provide reliable overload and short-circuit protection for industrial low-voltage distribution systems. As part of the Lovato P5ME moulded case circuit breaker series, it combines a rated current of 250 A with adjustable electronic protection, making it suitable for demanding power distribution, machinery and switchboard applications.
The P5ME3PS0250 features an electronic overload trip adjustment range of 100–250 A and an electronic short-circuit trip adjustment range of 150–2500 A. These adjustable protection settings allow the breaker to be configured for the characteristics of the protected circuit, helping engineers achieve effective protection and coordination across industrial electrical installations.
With an ultimate short-circuit breaking capacity Icu of 50 kA at 380–415 V AC and a rated operational voltage of up to 690 V AC, the P5ME3PS0250 delivers substantial fault-interruption capability. Its compact screw-mounted moulded-case construction makes it suitable for integration into industrial switchboards, distribution panels and machinery electrical systems.

Reliable Circuit Protection for Industrial Distribution
Moulded case circuit breakers such as the Lovato P5ME3PS0250 protect electrical installations against damaging overload and short-circuit currents. The electronic trip system monitors current through the breaker and disconnects the protected circuit when operating conditions exceed the configured protection thresholds.
The adjustable overload and short-circuit settings of the P5ME3PS0250 allow protection to be matched more closely to conductor ratings and downstream equipment. Combined with its high short-circuit breaking capacity and broad operating voltage range, this makes the breaker well suited to industrial distribution systems requiring dependable fault interruption and configurable circuit protection.
Typical Applications
- Industrial low-voltage distribution boards.
- Main and sub-distribution circuits.
- Industrial machinery power supplies.
- Electrical control panels and switchboards.
- Feeder and cable protection.
- Manufacturing and process automation installations.
