Why Choose the Lovato P2MB2PD100 Miniature Circuit Breaker?
The Lovato P2MB2PD100 is a robust 2-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 combines thermal and magnetic protection with a high current rating for industrial and commercial electrical distribution applications.
Featuring a 100 A rated current, D tripping curve and 10 kA short-circuit breaking capacity, the P2MB2PD100 is particularly suitable for circuits supplying loads with relatively high starting or inrush currents. Its two protected poles provide simultaneous circuit protection in compatible AC electrical systems.
The P2MB2PD100 is rated for operation up to 400 V AC and occupies 3 DIN modules. Its modular construction enables straightforward installation inside distribution boards and electrical control panels, while compatibility with IEC/EN/BS and UL 1077 requirements makes it suitable for a broad range of professional circuit protection applications.

Reliable Thermal-Magnetic Circuit Protection
Miniature circuit breakers such as the Lovato P2MB2PD100 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 particularly useful for electrical loads that can produce substantial but legitimate starting currents. This makes the P2MB2PD100 well suited to appropriately engineered circuits supplying equipment such as motors, transformers and other inductive loads where a less tolerant trip characteristic could cause unwanted operation during start-up.
Typical Applications
- Industrial electrical distribution boards.
- Machinery and automation control panels.
- Motor and inductive-load supply circuits.
- Transformer supply circuits.
- Commercial and industrial electrical installations.
- Circuits with high starting or inrush currents.
