Why Choose the Lovato P1MB4PC20 Miniature Circuit Breaker?

The Lovato P1MB4PC20 is a high-performance four-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. As part of the Lovato Electric P1MB modular protection range, it combines dependable thermal-magnetic protection with a compact DIN rail mounted design suitable for industrial machinery, commercial installations and electrical distribution systems.

Featuring a 20 A rated current, a Type C tripping characteristic and a 10 kA short-circuit breaking capacity, this MCB is ideal for protecting circuits supplying motors, transformers, power supplies and other equipment with moderate inrush currents. Its robust construction delivers reliable performance while complying with recognised international standards.

The four mechanically linked poles provide simultaneous isolation of all conductors during fault conditions, improving electrical safety and simplifying maintenance. Its compact four-module design allows straightforward installation within switchboards, control panels and automation cabinets.

Key Advantages

  • Reliable overload and short-circuit protection.
  • Four-pole configuration for complete circuit isolation.
  • 20 A rated current for industrial and commercial circuits.
  • Type C tripping characteristic for moderate inrush currents.
  • 10 kA breaking capacity for dependable fault protection.
  • Compact modular DIN rail design for efficient panel layouts.

Key Features

  • Lovato Electric P1MB miniature circuit breaker series.
  • Four-pole thermal-magnetic protection.
  • 20 A rated operational current.
  • Type C tripping characteristic.
  • 10 kA IEC short-circuit breaking capacity.
  • Current-limiting class 3 performance.
  • Positive contact position indicator.
  • 35 mm DIN rail mounting.

Reliable Protection for Industrial Power Circuits

Miniature circuit breakers automatically disconnect electrical supplies whenever overload or short-circuit conditions occur. Thermal protection responds to sustained overloads, while magnetic protection rapidly interrupts fault currents before damage can occur to connected wiring and equipment.

The Lovato P1MB4PC20 combines a 20 A current rating with a Type C tripping curve, making it suitable for electrical systems supplying motors, transformers and other inductive loads. Its four-pole design provides simultaneous isolation of all conductors, improving safety during maintenance and fault finding.

Typical Applications

  • Industrial machinery and automation systems.
  • Three-phase distribution boards.
  • Motor and transformer protection.
  • Commercial electrical installations.
  • Control panels and OEM equipment.
  • Building services and infrastructure.
