Why Choose the Lovato P2MB3PD080 Miniature Circuit Breaker?
The Lovato P2MB3PD080 is a high-performance three-pole miniature circuit breaker (MCB) designed to protect three-phase electrical circuits against overloads and short circuits. Part of the Lovato Electric P2 MB modular protection range, it provides dependable thermal-magnetic protection for industrial machinery, control panels and power-distribution systems.
Featuring an 80 A rated current, D tripping curve and 10 kA short-circuit breaking capacity, the P2MB3PD080 is particularly suitable for equipment with high starting or magnetising currents. Its D characteristic helps prevent nuisance tripping when supplying motors, transformers, solenoids and other loads that generate substantial temporary inrush currents.
The circuit breaker has a 3P configuration, occupies 4.5 DIN modules and is designed for 230/400 V AC systems. Its mechanically linked poles disconnect all three protected phases simultaneously, providing reliable isolation and circuit protection in demanding commercial and industrial installations.
Key Advantages
- Provides reliable overload and short-circuit protection.
- 80 A rated current for higher-capacity three-phase circuits.
- D tripping curve accommodates high motor and transformer inrush currents.
- Three-pole switching disconnects all protected phases simultaneously.
- 10 kA short-circuit breaking capacity for dependable fault interruption.
- Compact modular construction for professional panel installations.

Protection for High-Inrush Three-Phase Loads
The Lovato P2MB3PD080 continuously monitors the current flowing through all three protected phases. Its thermal release responds to prolonged overload conditions, while the magnetic release disconnects the supply rapidly when a severe short-circuit fault occurs.
The D tripping characteristic is intended for equipment that can produce substantially higher starting currents than conventional resistive loads. This makes the breaker particularly suitable for large motors, transformers, solenoids and industrial machinery where a B or C curve device could trip unnecessarily during normal start-up.
Typical Applications
- Industrial motor supply circuits.
- Transformers and equipment with high magnetising currents.
- Industrial machinery and OEM electrical systems.
- Three-phase control panels and switchboards.
- Solenoids and electromagnetic equipment.
- Commercial and industrial power-distribution systems.
