Why Choose the Lovato P1MBUH2PD02 Miniature Circuit Breaker?
The Lovato P1MBUH2PD02 is a two-pole miniature circuit breaker (MCB) designed for dependable branch-circuit protection in industrial electrical panels, machinery and automation systems. Part of the Lovato P1 MB series, this model combines a 2 A rated current with a Curve D tripping characteristic, making it suitable for low-current circuits where comparatively high momentary inrush currents can occur.
The P1MBUH2PD02 is rated for 480Y/277 V AC under UL and provides a 10 kA short-circuit rating under both UL and IEC specifications. Its thermal-magnetic operating principle provides automatic overload and short-circuit protection, while UL489 compliance supports use in appropriate branch-circuit protection applications.
Occupying two DIN modules, the breaker installs on a standard 35 mm DIN rail and accepts IEC conductor sections from 1 to 35 mm². A wide -40 to +70 °C operating temperature range, 20,000-cycle mechanical life and robust modular construction make it well suited to professional industrial electrical installations.

Reliable UL489 Protection for High-Inrush Loads
The Lovato P1MBUH2PD02 provides automatic protection against damaging overcurrent conditions using a thermal-magnetic operating mechanism. The thermal element responds to sustained overloads, while the magnetic element provides rapid operation during short-circuit faults to help protect conductors and connected electrical equipment.
Its Curve D characteristic offers increased tolerance for momentary starting currents compared with Curve C breakers, making it suitable for appropriately engineered circuits with higher inrush characteristics. Combined with its 2 A rating, two-pole construction, 480Y/277 V AC UL rating and 10 kA short-circuit capability, the P1MBUH2PD02 provides robust protection for demanding industrial installations.
Typical Applications
- UL489 branch-circuit protection.
- Industrial electrical control panels.
- Low-current machine and automation circuits.
- Circuits with relatively high momentary inrush currents.
- Industrial power distribution assemblies.
- DIN rail-mounted circuit protection systems.
