Why Choose the Lovato P1MB1PB25 Miniature Circuit Breaker?

The Lovato P1MB1PB25 is a compact and reliable miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. As part of the Lovato P1MB modular circuit protection range, it provides dependable protection for residential, commercial and industrial electrical installations.

This circuit breaker features a 25 A rated current, a Type B tripping characteristic and a high 10 kA short-circuit breaking capacity. Its Type B response makes it particularly suitable for circuits supplying resistive or low-inrush loads, including lighting, heating, socket outlets and general electrical equipment.

With a single-pole configuration and compact one-module DIN rail design, the P1MB1PB25 can be installed easily in distribution boards, switchboards and industrial control panels. Its thermal-magnetic operating mechanism provides automatic disconnection during sustained overload conditions and sudden short-circuit faults.

Key Advantages

  • Reliable overload and short-circuit protection.
  • 25 A rated current for general electrical circuits and equipment.
  • Type B tripping characteristic for loads with relatively low inrush currents.
  • High 10 kA breaking capacity for effective fault protection.
  • Compact single-module construction saves valuable panel space.
  • DIN rail mounting enables quick and straightforward installation.

Key Features

  • Lovato P1MB miniature circuit breaker series.
  • 25 A rated operational current.
  • Single-pole configuration.
  • Type B thermal-magnetic tripping characteristic.
  • 10 kA short-circuit breaking capacity.
  • 230 V AC rated operational voltage.
  • Suitable for operation at up to 60 V DC.
  • Standard 35 mm DIN rail mounting.
  • Compact one-module width.
  • Screw terminals for secure conductor connections.

Reliable Circuit Protection for Electrical Installations

Miniature circuit breakers protect electrical cables, connected equipment and installations by automatically disconnecting the power supply whenever excessive current is detected. The Lovato P1MB1PB25 combines thermal protection for prolonged overload conditions with magnetic protection for rapid operation during short-circuit faults.

The Type B tripping characteristic is intended for circuits with low to moderate starting currents. This makes the P1MB1PB25 suitable for lighting, heating, socket outlet circuits, control equipment and other general-purpose loads requiring dependable 25 A protection.

Typical Applications

  • Residential and commercial distribution boards.
  • Lighting and socket outlet circuits.
  • Heating and resistive electrical loads.
  • Industrial control panels and switchboards.
  • Machinery auxiliary power circuits.
  • Building services installations.
  • Automation and control equipment.
