Why Choose the Lovato P1MBUH2PD10 Miniature Circuit Breaker?

The Lovato P1MBUH2PD10 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 10 A rated current with a Curve D tripping characteristic, making it particularly suitable for circuits where relatively high momentary starting or inrush currents can occur.

The P1MBUH2PD10 is rated for 480Y/277 V AC under UL and provides a 10 kA short-circuit rating. Its thermal-magnetic operating principle provides automatic protection against sustained overloads and short-circuit faults, while UL489 compliance supports its use for appropriate branch-circuit protection applications.

The two-pole construction provides coordinated switching and protection across both poles, while its modular design supports straightforward integration into DIN rail-mounted electrical assemblies. This combination of 10 A capacity, Curve D response and UL489 branch-circuit protection makes the P1MBUH2PD10 a practical choice for demanding industrial control and distribution systems.

Key Advantages

  • 10 A two-pole miniature circuit breaker for industrial branch circuits.
  • UL489 compliant for appropriate branch-circuit protection applications.
  • Curve D tripping characteristic accommodates relatively high momentary inrush currents.
  • Rated for 480Y/277 V AC under UL.
  • 10 kA short-circuit rating for robust fault protection.
  • Thermal-magnetic operation protects against both overloads and short circuits.
  • Compact modular construction for space-efficient industrial panel installation.

Key Features

  • Lovato P1 MB miniature circuit breaker series.
  • Two-pole (2P) configuration.
  • 10 A rated current.
  • Curve D tripping characteristic.
  • 480Y/277 V AC UL system rating.

  • DIN rail-compatible modular construction.

Reliable UL489 Protection for High-Inrush Loads

The Lovato P1MBUH2PD10 provides automatic protection against damaging overcurrent conditions using a thermal-magnetic operating mechanism. Its thermal element responds to sustained overload conditions, while magnetic operation provides rapid interruption when a severe short-circuit fault occurs.

Its Curve D characteristic provides increased tolerance for temporary starting currents compared with Curve C breakers, making it appropriate for suitably engineered circuits supplying equipment with higher inrush characteristics. Combined with its 10 A rating, two-pole construction, 480Y/277 V AC UL rating and 10 kA short-circuit capability, the P1MBUH2PD10 delivers dependable industrial branch-circuit protection.

Typical Applications

  • UL489 branch-circuit protection.
  • Industrial electrical control panels.
  • Machine and automation systems.
  • Circuits with relatively high starting or inrush currents.
  • Industrial power distribution assemblies.
  • DIN rail-mounted circuit protection systems.
