Why Choose the Lovato P1MB1PB50 Miniature Circuit Breaker?

The Lovato P1MB1PB50 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 50 A rated current, a Type B tripping characteristic and a high 10 kA short-circuit breaking capacity. The Type B response is suitable for circuits supplying resistive and relatively low-inrush loads, helping protect cables and connected equipment while reducing unnecessary interruptions during normal operation.

With its single-pole configuration and space-saving one-module DIN rail design, the P1MB1PB50 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

  • Dependable overload and short-circuit protection.
  • 50 A rated current for higher-capacity electrical circuits.
  • Type B tripping characteristic for circuits with relatively low inrush currents.
  • High 10 kA short-circuit breaking capacity.
  • Compact single-module construction saves valuable panel space.
  • DIN rail mounting supports quick and straightforward installation.

Key Features

  • Lovato P1MB miniature circuit breaker series.
  • 50 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.
  • 80 V DC rated operational voltage.
  • Rated insulation voltage of 440 V.
  • Rated impulse withstand voltage of 4 kV.
  • Standard 35 mm DIN rail mounting.

Reliable Circuit Protection for Electrical Installations

Miniature circuit breakers protect electrical cables, equipment and connected loads by automatically disconnecting the power supply whenever excessive current is detected. The Lovato P1MB1PB50 combines thermal protection for sustained overload conditions with magnetic protection for rapid operation during short-circuit faults.

Its 50 A rating makes it suitable for higher-capacity final circuits, distribution circuits and equipment supplies where a Type B response is appropriate. The compact modular design also helps panel builders and electrical contractors maximise the available space inside electrical enclosures.

Typical Applications

  • Residential and commercial distribution boards.
  • Higher-capacity power distribution circuits.
  • Industrial switchboards and control panels.
  • Heating and resistive electrical loads.
  • Machinery auxiliary power supplies.
  • Building services installations.
  • Automation and OEM equipment.
