Why Choose the Lovato P5ME3PS0630 630A Moulded Case Circuit Breaker?
The Lovato P5ME3PS0630 is a high-performance 3-pole moulded case circuit breaker (MCCB) from the Lovato P5ME series, designed for protection of industrial low-voltage electrical distribution systems. Rated at 630 A, it incorporates an electronic trip unit with adjustable overload and short-circuit protection for effective coordination with the protected circuit.
At 380–415 V AC, the P5ME3PS0630 provides an ultimate short-circuit breaking capacity Icu of 65 kA and a service short-circuit breaking capacity Ics of 65 kA. Its electronic overload trip can be adjusted from 252–630 A, while the electronic short-circuit trip can be adjusted from 378–6300 A, providing substantial flexibility for industrial protection coordination.
The breaker supports an AC rated operational voltage up to 690 V, with a rated insulation voltage of 1000 V and rated impulse withstand voltage of 8 kV. A robust 20,000-cycle mechanical endurance, wide operating temperature range and flexible mounting options make the P5ME3PS0630 suitable for demanding switchboards, machinery and industrial power-distribution installations.

Adjustable Electronic Protection for High-Current Distribution Systems
The Lovato P5ME3PS0630 combines overload and short-circuit protection within an adjustable electronic trip system. Its 252–630 A overload adjustment range enables the protection threshold to be coordinated with the load and conductor requirements, while the 378–6300 A short-circuit adjustment range provides additional flexibility when coordinating downstream and upstream protection devices.
Short-circuit performance is particularly strong on common industrial three-phase networks, with both Icu and Ics rated at 65 kA at 380–415 V AC. The breaker also maintains defined breaking capacities at higher system voltages, making it suitable for a broad range of industrial power-distribution architectures.
Typical Applications
- Industrial low-voltage distribution boards.
- Main and sub-distribution switchboards.
- High-current three-phase machinery circuits.
- Manufacturing and process automation systems.
- Industrial plant electrical distribution.
- Commercial and infrastructure power systems.
- OEM electrical panels and machinery.
- High fault-level circuits requiring adjustable electronic protection.
