## Summary description

EATON HN-B50/3 is a 3-pole circuit breaker with 50 A rated current designed for combined overcurrent and residual current protection. The device provides short-circuit breaking capacity of 6 kA and is intended for protecting electrical circuits against overloads, short circuits and leakage currents in residential and light commercial installations.

## Long 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.
