Why Choose the Lovato P1MBUH1PD10 Miniature Circuit Breaker?

The Lovato P1MBUH1PD10 is a compact single-pole miniature circuit breaker (MCB) designed for reliable 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 higher starting or inrush currents can occur.

The P1MBUH1PD10 is rated for 277 V AC under UL and provides a 10 kA short-circuit rating under both UL and IEC specifications. Its thermal-magnetic protection provides dependable response to sustained overloads and short-circuit faults, while compliance with UL489 supports use in appropriate branch-circuit protection applications.

Occupying only one DIN module, the P1MBUH1PD10 installs on a standard 35 mm DIN rail and accepts IEC conductors from 1 to 35 mm². With IP20 frontal protection, a wide operating temperature range and a mechanical life of 20,000 cycles, it provides a robust and space-efficient solution for professional industrial electrical installations.

Key Advantages

  • 10 A single-pole miniature circuit breaker for branch-circuit protection.
  • Curve D tripping characteristic for loads with higher starting and inrush currents.
  • 277 V AC UL rated operational voltage.
  • 10 kA UL and IEC short-circuit rating.
  • UL489 compliant for suitable branch-circuit protection applications.
  • Compact single-module format conserves DIN rail space.
  • Wide 1–35 mm² conductor connection range.

Key Features

  • Lovato P1 MB miniature circuit breaker series.
  • Single-pole (1P) configuration.
  • 10 A rated current.
  • Curve D tripping characteristic.
  • 230/400 V AC IEC rated operational voltage.
  • 277 V AC UL rated operational voltage.
  • 60 V DC rated operational voltage.
  • 10 kA short-circuit rating.
  • 440 V rated insulation voltage and 4 kV impulse withstand voltage.
  • IP20 frontal protection and 35 mm DIN rail mounting.

Reliable UL489 Protection for High-Inrush Loads

Miniature circuit breakers automatically interrupt electrical circuits when excessive current threatens conductors or connected equipment. The Lovato P1MBUH1PD10 combines thermal overload protection with magnetic short-circuit protection, providing automatic disconnection under damaging overcurrent conditions.

Its Curve D characteristic provides greater tolerance for temporary inrush currents than Curve C devices, making this breaker useful for appropriate industrial loads with substantial starting currents. Combined with its 10 A rating, 277 V AC UL rating and 10 kA short-circuit capability, the P1MBUH1PD10 provides dependable protection in demanding industrial installations.

Typical Applications

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