Circuit Breaker EATON HN-B32/1 single-phase 32A Type B

EATON HN-B32/1 single-phase 32A Type B circuit breaker provides overcurrent protection for residential and light commercial electrical installations. The device is designed to interrupt overloads and short-circuits in single-phase circuits, protecting lighting circuits, socket outlets and small appliances. It fits standard DIN-rail distribution boards and is intended for use where a 32 ampere, Type B characteristic is required.

Advantages

The circuit breaker combines a compact form factor with a clear trip characteristic, enabling predictable response to overloads and short circuits. Its Type B curve offers fast tripping for low-magnitude faults typical of domestic and light commercial loads, while providing stable operation under normal load conditions. The unit is compatible with standard modular panel mounting and allows straightforward installation and replacement without additional enclosure modifications.

Suitable for

• Protection of lighting circuits in homes and apartments
• Protection of socket outlets and small appliance circuits
• Small commercial or office branch circuits with predominantly resistive loads
• DIN-rail distribution boards where a 32 A, Type B breaker is required

Key specifications

• Rated current: 32 A
• Poles: single-phase (1-pole)
• Tripping characteristic: Type B (fast, for low-inrush circuits)
• Function: overcurrent protection (overload and short-circuit)
• Mounting: standard DIN-rail modular mounting
• Application: residential and light commercial branch circuit protection

How to use

Install the breaker on a standard DIN-rail inside the distribution board following local electrical codes. Connect the phase conductor to the breaker input terminal and the load conductor to the output terminal, ensuring proper tightening of terminals to the recommended torque. Use the breaker as the upstream protective device for the intended 32 A circuit. After installation, verify correct operation by switching the device on and off and test the protected circuit under no-load conditions before full energization.

Usage recommendations

Choose this Type B 32 A breaker for circuits with predominantly resistive loads and low inrush currents, such as general lighting and ordinary socket outlets; avoid using it on circuits with high motor or transformer inrush unless additional coordination or a different tripping curve is specified. Follow applicable wiring regulations and periodic inspection routines to ensure continued protective performance.
