Why Choose the Lovato P1MBUH2PD25 Miniature Circuit Breaker?

The Lovato P1MBUH2PD25 is a compact two-pole miniature circuit breaker (MCB) designed to provide thermal-magnetic overcurrent and short-circuit protection in industrial electrical distribution and control systems. Part of the Lovato P1 MBUH range, it combines a 25 A rated current with Curve D tripping characteristics and UL489 compliance for dependable branch circuit protection.

The P1MBUH2PD25 is designed for 480Y/277 V AC systems and provides a 10 kA short-circuit breaking capacity. Its two protected poles provide coordinated protection and disconnection, while the compact two-module format makes efficient use of space within machinery, automation equipment, OEM assemblies and industrial control panels.

A Curve D tripping characteristic provides increased tolerance of relatively high transient inrush currents, making this breaker suitable for compatible inductive and high-starting-current loads. With IP20 protection, conductor capacity up to 35 mm², a wide operating temperature range and DIN rail mounting, the P1MBUH2PD25 provides a robust solution for demanding industrial installations.

Key Advantages

  • Two-pole thermal-magnetic protection for industrial branch and equipment circuits.
  • 25 A rated current for a wide range of industrial electrical loads.
  • Curve D tripping characteristic suitable for circuits with relatively high transient inrush currents.
  • Designed for 480Y/277 V AC electrical systems.
  • 10 kA short-circuit breaking capacity for robust fault protection.
  • UL489 compliant for branch circuit protection applications.

Key Features

  • Lovato P1 MBUH miniature circuit breaker range.
  • 2-pole configuration with 2 protected poles.
  • 25 A rated current.
  • Curve D tripping characteristic.
  • 480Y/277 V AC system rating.
  • 10 kA short-circuit breaking capacity.
  • 1000 V rated insulation voltage Ui.
  • 4 kV rated impulse withstand voltage Uimp.
  • 20,000-cycle mechanical endurance.
  • Front protection rating of IP20 with DIN rail mounting.

Reliable Curve D UL489 Branch Circuit Protection

The Lovato P1MBUH2PD25 uses a thermal-magnetic operating mechanism to protect electrical circuits against sustained overloads and short circuits. The thermal element responds to prolonged overcurrent conditions, while the magnetic element provides rapid interruption during severe fault-current events, helping protect conductors and connected electrical equipment.

Its Curve D characteristic provides increased tolerance of high transient starting currents, making the P1MBUH2PD25 particularly suitable for compatible transformers, power supplies, solenoids and other inductive or high-inrush loads. Combined with its 25 A current rating, 480Y/277 V AC system rating and 10 kA breaking capacity, it provides a robust two-pole solution for industrial branch circuit protection.

Typical Applications

  • Industrial electrical control panels.
  • UL489 branch circuit protection.
  • 480Y/277 V AC industrial electrical systems.
  • Industrial machinery and automation equipment.
  • Compatible transformer, solenoid and power supply circuits with high inrush currents.
  • OEM electrical control and distribution assemblies.
