Why Choose the Lovato P2MB3PC100 Miniature Circuit Breaker?

The Lovato P2MB3PC100 is a robust three-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. Part of the Lovato Electric P2 MB modular protection range, it provides dependable thermal-magnetic protection for industrial machinery, control panels and three-phase power-distribution systems.

Featuring a 100 A rated current, C tripping curve and 10 kA short-circuit breaking capacity, the P2MB3PC100 is suitable for circuits supplying equipment with moderate starting currents. Its C curve characteristic accommodates temporary inrush currents from motors, transformers and other inductive loads while maintaining reliable protection during genuine fault conditions.

The circuit breaker has a 3P configuration, occupies 4.5 DIN modules and operates on 230/400 V AC electrical systems. Its mechanically linked three-pole design disconnects all protected phases simultaneously, making it a dependable solution for demanding commercial and industrial installations.

Key Advantages

  • Provides reliable overload and short-circuit protection.
  • 100 A rated current for high-capacity three-phase circuits.
  • Three-pole switching disconnects all protected phases simultaneously.
  • C tripping curve accommodates moderate equipment starting currents.
  • 10 kA short-circuit breaking capacity for dependable fault interruption.
  • Compact modular format for professional control-panel installations.

Key Features

  • Lovato Electric P2 MB miniature circuit breaker.
  • Three-pole configuration.
  • 100 A rated current.
  • C curve thermal-magnetic tripping characteristic.
  • 10 kA IEC short-circuit breaking capacity.
  • 230/400 V AC rated operational voltage.
  • 400 V rated insulation voltage.
  • 4 kV rated impulse withstand voltage.
  • 10,000 electrical and mechanical operating cycles.
  • Standard 35 mm DIN rail mounting.

Reliable Three-Phase Circuit Protection

The Lovato P2MB3PC100 monitors the current flowing through all three protected phases and automatically disconnects the electrical supply when an overload or short circuit occurs. Its thermal release responds to sustained overcurrent conditions, while the magnetic release operates rapidly during severe short-circuit faults.

The C curve characteristic makes this circuit breaker suitable for loads with moderate inrush currents, including motors, transformers, lighting systems and industrial machinery. Its mechanically linked three-pole mechanism ensures all phases are disconnected together for dependable three-phase isolation.

Typical Applications

  • Industrial control panels and switchboards.
  • Three-phase machinery and OEM electrical systems.
  • Commercial power-distribution boards.
  • Motor and transformer supply circuits.
  • Heating, ventilation and air-conditioning equipment.
  • Industrial lighting and power-distribution systems.
