Why Choose the Lovato P2MB4PD080 Miniature Circuit Breaker?
The Lovato P2MB4PD080 is a robust 4-pole miniature circuit breaker (MCB) designed to protect low-voltage electrical circuits against overloads and short circuits. As part of the Lovato P2MB series, it provides thermal-magnetic circuit protection for industrial and commercial electrical distribution systems where dependable multi-pole protection is required.
Featuring an 80 A rated current, D tripping curve and 10 kA IEC short-circuit rating, the P2MB4PD080 is particularly suitable for circuits supplying loads with relatively high starting or inrush currents. Its four-pole configuration enables simultaneous switching and protection across compatible three-phase electrical circuits with neutral.
With a rated operational voltage of 230/400 V AC and a frequency rating of 50/60 Hz, the P2MB4PD080 is designed for professional low-voltage distribution applications. Its 6-module construction mounts on a standard 35 mm DIN rail, allowing straightforward integration into distribution boards and industrial control panels.

Reliable Thermal-Magnetic Protection for High-Inrush Loads
Miniature circuit breakers such as the Lovato P2MB4PD080 automatically interrupt a circuit when excessive current occurs. Thermal protection responds to sustained overload conditions, while the magnetic release provides rapid interruption during severe short-circuit faults, helping protect conductors and connected electrical equipment.
The D-curve characteristic is intended for circuits where relatively high but legitimate starting currents can occur, making the P2MB4PD080 particularly useful for appropriately engineered circuits supplying motors, transformers and other inductive loads. Its four-pole construction provides coordinated switching across all four poles for compatible multi-phase distribution applications.
Typical Applications
- Industrial three-phase electrical distribution boards.
- Machinery and automation control panels.
- Motor and high-inrush load supply circuits.
- Transformer and inductive-load circuits.
- Commercial and industrial electrical installations.
- Four-pole circuits requiring overload and short-circuit protection.
