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.
