Why Choose the Lovato P1MB2PD50 Miniature Circuit Breaker?

The Lovato P1MB2PD50 is a robust and dependable 2-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. As part of the professional Lovato P1MB circuit protection series, it is suitable for industrial control panels, commercial distribution boards, machine building and OEM electrical equipment.

This miniature circuit breaker uses thermal and magnetic tripping mechanisms to automatically disconnect the protected circuit when an overload or short circuit occurs. Its D tripping characteristic accommodates high instantaneous starting currents, making it suitable for transformers, motors, solenoids and other equipment with demanding energisation characteristics.

With a rated current of 50 A, a 10 kA short-circuit breaking capacity and a compact 2-module DIN rail format, the P1MB2PD50 provides dependable protection for higher-load circuits with substantial inrush demands. Its 230/400 V AC operational voltage, robust construction and recognised international conformity support reliable performance in demanding electrical installations.

Key Advantages

  • Compact 2-pole miniature circuit breaker for professional electrical installations.
  • 50 A rated current suitable for higher-capacity industrial circuits.
  • D tripping characteristic accommodates high equipment starting currents.
  • 10 kA short-circuit breaking capacity for dependable fault protection.
  • Thermal-magnetic operation protects against overloads and short circuits.
  • Simple installation onto a standard 35 mm DIN rail.

Key Features

  • Lovato P1MB miniature circuit breaker series.
  • 50 A rated current.
  • 2-pole configuration.
  • D tripping characteristic.
  • 10 kA short-circuit breaking capacity.
  • 230/400 V AC rated operational voltage.
  • 125 V DC rated operational voltage.

  • Compact two-module DIN rail mounted design.
  • Manufactured to recognised IEC, EN, UL and CSA standards.

Reliable Protection for High-Inrush Electrical Loads

Miniature circuit breakers such as the Lovato P1MB2PD50 automatically disconnect electrical circuits during overload or short-circuit conditions. This helps protect conductors, machinery and connected equipment from excessive temperatures and damaging fault currents while improving overall electrical safety.

The D curve characteristic allows the breaker to tolerate high instantaneous starting currents without unnecessary tripping. Combined with its 50 A current rating, two-pole construction and 10 kA breaking capacity, the P1MB2PD50 is well suited to transformers, motors and other highly inductive equipment.

Typical Applications

  • Industrial automation control panels.
  • Transformers and electrical power supplies.
  • Motors and highly inductive loads.
  • Solenoids and electromagnetic equipment.
  • Machine building and OEM equipment.
  • Commercial and industrial distribution boards.
