Product information

Description

The Hager MBN320 3-pole circuit breaker is a reliable electrical protection device engineered to safeguard residential and commercial distribution systems. Designed with a 20 A nominal current rating and supporting a 50 Hz alternating current input frequency, this 3-pole circuit breaker effectively disconnects power during overcurrent and short-circuit events. It integrates seamlessly into standard electrical enclosures, offering dependable performance for multi-phase circuits.

Advantages

This Hager circuit breaker provides robust protection against electrical faults, helping to prevent equipment damage and reduce fire hazards in wiring systems. Its standard three-pole configuration allows for simultaneous disconnection of all phases, ensuring enhanced safety during maintenance or fault conditions. Built to meet stringent industry standards, it offers consistent operation and long-term durability in various electrical installations.

Suitable for

  • Residential electrical distribution boards
  • Commercial building sub-distribution systems
  • Three-phase motor and equipment protection
  • Safeguarding standard wiring against overloads and short circuits

When it may not be suitable

This device is not designed for direct current (DC) electrical systems or applications requiring a nominal current rating other than 20 A. It should not be used in environments exceeding its specified short-circuit breaking capacity without appropriate backup protection.

Key specifications

  • 3-pole configuration
  • 20 A nominal current
  • 50 Hz AC input frequency
  • Designed for electrical installation protection

How to use

Installation should be performed exclusively by a qualified electrician in compliance with local electrical codes and safety regulations. The circuit breaker is mounted onto a standard DIN rail within a suitable enclosure. Ensure all terminal screws are securely tightened to the manufacturer's recommended torque specifications to prevent loose connections before energizing the circuit.

What to consider before purchase

  • Verify that the 20 A nominal current matches the electrical load requirements of your circuit
  • Confirm compatibility with your existing distribution board and DIN rail mounting space
  • Check that the 3-pole setup aligns with your phase requirements
Usage recommendations: Regularly inspect the installation for signs of wear or thermal damage, and periodically test the functionality of the distribution system in accordance with local safety standards.
