Why Choose the Lovato P1MBUH3PC16 Miniature Circuit Breaker?

The Lovato P1MBUH3PC16 is a robust three-pole miniature circuit breaker (MCB) designed to protect industrial and commercial electrical circuits against overloads and short circuits. As part of the dependable Lovato Electric P1MB series, it combines thermal and magnetic protection in a compact modular device suitable for professional control-panel and distribution applications.

With a rated current of 16 A, a Type C tripping characteristic and a short-circuit breaking capacity of 10 kA, the P1MBUH3PC16 is well suited to circuits containing equipment with moderate starting currents. It can be used with machinery, motors, transformers, contactors, power supplies and other inductive electrical loads.

The breaker features a three-pole configuration and occupies three DIN modules, allowing all three phases to be disconnected together when a fault occurs. Its compatibility with IEC/EN 60947-2 and UL 489 requirements makes it suitable for a wide range of industrial installations and internationally specified machinery.

Key Advantages

  • Dependable three-pole overload and short-circuit protection.
  • 16 A rated current for three-phase electrical circuits.
  • Type C tripping curve for loads with moderate inrush currents.
  • High 10 kA short-circuit breaking capacity.
  • Compact three-module design helps conserve control-panel space.
  • Standard DIN rail mounting simplifies installation and replacement.
  • Suitable for installations designed to IEC and UL standards.

Key Features

  • Lovato Electric P1MB series miniature circuit breaker.
  • Three-pole configuration.
  • 16 A nominal current rating.
  • Type C thermal-magnetic tripping characteristic.
  • 10 kA short-circuit breaking capacity.
  • 230/400 V AC operational voltage under IEC conditions.
  • 480Y/277 V AC operational voltage under UL conditions.
  • 50/60 Hz rated frequency.
  • Compact three-DIN-module construction.
  • Suitable for standard DIN rail mounting.

Reliable Protection for Three-Phase Electrical Circuits

The Lovato P1MBUH3PC16 uses a thermal-magnetic operating mechanism to provide two complementary forms of protection. Its thermal element responds to sustained overload conditions, while the magnetic element rapidly disconnects the circuit when a high short-circuit current is detected.

The Type C response characteristic allows the breaker to accommodate moderate temporary inrush currents while maintaining dependable fault protection. This makes it particularly useful in industrial control systems containing motors, transformers, contactors, solenoids and other equipment that may draw additional current during start-up.

Typical Applications

  • Industrial control panels.
  • Three-phase machinery circuits.
  • Motor starters and automation equipment.
  • Transformers and inductive loads.
  • Commercial electrical distribution systems.
  • Manufacturing and processing machinery.
  • OEM machine-building projects.
  • Control power and auxiliary circuits.
