Why Choose the Lovato P1MB1PB01 Miniature Circuit Breaker?

The Lovato P1MB1PB01 is a compact and reliable miniature circuit breaker (MCB) designed to protect low-voltage electrical circuits against overloads and short circuits. As part of the Lovato Electric P1MB series, it combines dependable thermal-magnetic protection with a space-saving modular format for distribution boards, industrial control panels and machinery installations.

Featuring a 1 A rated current, Type B tripping characteristic and 10 kA short-circuit breaking capacity, the P1MB1PB01 is particularly suitable for low-current circuits with limited starting currents. It provides effective protection for sensitive control wiring, instrumentation, signalling devices and electronic equipment.

The breaker has a single-pole configuration and occupies only one DIN module, helping maximise available space inside electrical enclosures. Its standard 35 mm DIN rail mounting and screw-terminal connections support fast, secure installation in commercial and industrial electrical systems.

Key Advantages

  • Dependable overload and short-circuit protection for low-current circuits.
  • 1 A rated current suitable for control and instrumentation equipment.
  • Type B tripping characteristic provides sensitive protection for low-inrush loads.
  • 10 kA breaking capacity supports reliable interruption of high fault currents.
  • Compact single-pole, one-module design.
  • Thermal-magnetic operation provides automatic fault disconnection.
  • Suitable for AC and DC low-voltage circuit applications.
  • Simple installation on a standard 35 mm DIN rail.

Key Features

  • Lovato Electric P1MB series.
  • 1 A rated current.
  • Type B tripping curve.
  • Single-pole configuration.
  • 10 kA short-circuit breaking capacity.
  • 230 V AC rated operational voltage.
  • 80 V DC rated operational voltage.
  • Thermal-magnetic tripping mechanism.
  • Compact one DIN module construction.
  • DIN rail mounting with screw-terminal connections.

Reliable Protection for Sensitive Low-Current Circuits

The Lovato P1MB1PB01 combines thermal and magnetic tripping technologies to protect electrical wiring and connected equipment. The thermal element responds to sustained overload conditions, whilst the magnetic mechanism rapidly disconnects the circuit when a high short-circuit current is detected.

Its Type B tripping characteristic provides rapid operation at relatively low fault-current multiples, making it suitable for resistive loads and circuits with minimal inrush current. The 1 A rating is especially useful for protecting control devices, monitoring equipment, instrumentation and other sensitive low-current components.

Typical Applications

  • Industrial control panels.
  • PLC input and output circuits.
  • Instrumentation and monitoring systems.
  • Electronic control equipment.
  • Signalling and alarm circuits.
  • Relays, timers and control devices.
  • Building-management systems.
  • Low-current auxiliary power circuits.
