Product information

Description

EATON HN-B50/3 is a three-pole circuit breaker with a rated current of 50 A that combines overcurrent and residual current protection in a single device. Designed for residential and light commercial electrical installations, this breaker protects circuits from overloads, short circuits and leakage currents. The unit offers a short-circuit breaking capacity of 6 kA and integrates both thermal-magnetic tripping for overcurrent protection and residual-current detection to reduce the risk of electric shock and fire caused by earth faults.

Advantages

The combined design of overcurrent and residual current protection reduces the need for separate devices, saving space in distribution boards and simplifying installation. Thermal-magnetic tripping ensures reliable overload and short-circuit response while residual-current protection adds detection of leakage currents. With a 6 kA breaking capacity, the device is suitable for common residential and small commercial supply conditions. The three-pole configuration supports balanced three-phase circuits and provides coordinated protection across all phases.

Suitable for

  • Protection of three-phase circuits in residential buildings
  • Small commercial installations and light industrial applications
  • Feeders to distribution boards and motor circuits with 50 A rated current
  • Locations where combined overcurrent and earth-leakage protection is required

Key specifications

  • Poles: 3-pole configuration for three-phase circuits
  • Rated current: 50 A
  • Type of protection: combined overcurrent (thermal-magnetic) and residual-current detection
  • Breaking capacity: 6 kA short-circuit interrupting capacity
  • Intended use: protection against overloads, short circuits and leakage currents

How to use

Install the circuit breaker on a compatible DIN-rail inside the distribution board following applicable electrical standards and safety regulations. Connect line and load conductors to the corresponding input and output terminals, observing correct phase sequencing for three-phase systems. Ensure proper torque on terminal connections and verify that the device rating (50 A) and breaking capacity (6 kA) match the supply and downstream equipment. After installation, test the residual-current function and the mechanical operation of the breaker before placing the circuit into regular service.

Usage recommendations

Use the breaker as part of a coordinated protection scheme; verify compatibility with upstream and downstream protective devices and perform periodic testing of residual-current operation. Replace the device if mechanical damage, corrosion or repeated nuisance tripping occurs. For installation and maintenance, follow local electrical codes and, where required, engage a qualified electrician.
