Why Choose the Lovato P1MB2PB63 Miniature Circuit Breaker?

The Lovato P1MB2PB63 is a robust 2-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. Part of the dependable Lovato P1MB series, it provides reliable thermal-magnetic circuit protection for commercial distribution boards, industrial control panels, machinery and OEM electrical equipment.

This miniature circuit breaker combines a 63A rated current, B tripping characteristic and 10kA short-circuit breaking capacity. The B curve response is particularly suitable for circuits supplying resistive and lightly inductive loads with relatively low starting currents, including heating systems and general electrical distribution applications.

The P1MB2PB63 occupies two DIN modules and mounts onto a standard 35mm DIN rail, enabling straightforward installation inside electrical enclosures and distribution boards. Its compact design, screw terminals and recognised international approvals make it a reliable choice for professional circuit protection installations.

Key Advantages

  • Reliable overload and short-circuit protection.
  • 63A rated current for higher-capacity electrical circuits.
  • B tripping characteristic for resistive and lightly inductive loads.
  • 10kA short-circuit breaking capacity.
  • Compact 2-pole, two-module construction.
  • Simple installation onto a standard 35mm DIN rail.

Key Features

  • Lovato P1MB miniature circuit breaker series.
  • 63A rated current.
  • 2-pole configuration.
  • B tripping characteristic.
  • 10kA breaking capacity.
  • 230/400V AC rated operational voltage.
  • 80V DC rated operational voltage.
  • 440V rated insulation voltage.
  • 4kV rated impulse withstand voltage.
  • Thermal-magnetic tripping mechanism.
  • Positive contact position indication.
  • Screw terminal connections.

Reliable Circuit Protection for Electrical Systems

Miniature circuit breakers use thermal and magnetic trip mechanisms to automatically disconnect an electrical circuit when an overload or short circuit occurs. This helps protect conductors, connected equipment and electrical installations from excessive temperatures and damaging fault currents.

The two-pole configuration of the Lovato P1MB2PB63 provides linked switching and protection across two conductors. Its 63A rating and B curve characteristic make it suitable for higher-capacity circuits with relatively low inrush currents, while the 10kA breaking capacity provides dependable fault interruption.

Typical Applications

  • Commercial electrical distribution boards.
  • Industrial control panels and switchboards.
  • Heating and resistive load circuits.
  • General electrical distribution systems.
  • Machine building and OEM equipment.
  • Building services and infrastructure installations.
