Reliable High-Current Protection for Industrial Distribution
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.
Typical Applications
- Main industrial low-voltage distribution boards.
- High-current feeder and sub-distribution circuits.
- Industrial machinery and automation power supplies.
- Commercial and industrial electrical switchboards.
- Four-pole three-phase distribution systems.
- Manufacturing, process and renewable energy installations.
