Circuit Breaker GACIA N8BH 10KA C 3P 32A — 3-pole, 32 A, C-characteristic, 10 kA breaking capacity

Three-pole miniature circuit breaker GACIA N8BH 10KA C 3P 32A provides overcurrent protection for three-phase circuits in residential and commercial electrical installations. The device offers a rated current of 32 A, a type C tripping characteristic suitable for general-purpose circuits with moderate inrush currents, and a short-circuit breaking capacity of 10 kA. It is intended for installation in distribution boards to protect branch circuits, motors and lighting circuits against overloads and short circuits.

Advantages

The breaker combines compact dimensions with reliable electromechanical tripping and clear characteristic behaviour, enabling predictable operation under overload and short-circuit conditions. Its 3-pole design ensures simultaneous disconnection of all phases, improving safety in three-phase systems. Rated for a 10 kA breaking capacity, it is suitable for installations where medium-level prospective fault currents are expected. The type C characteristic balances sensitivity to overloads with tolerance to temporary inrush currents from motors and lighting loads.

Suitable for

• Protection of three-phase distribution circuits in residential buildings
• Branch circuit protection for small commercial installations
• Protection of lighting circuits and general-purpose outlets
• Motor protection where moderate starting currents occur

Key specifications

• Poles: 3-pole compact miniature circuit breaker
• Rated current: 32 A
• Tripping characteristic: Type C (moderate inrush tolerance)
• Short-circuit breaking capacity: 10 kA
• Mounting: DIN-rail compatible (standard miniature breaker form factor)
• Application: Overcurrent protection for three-phase circuits, branch circuits, motors and lighting

How to use

Install the breaker into the distribution board on a suitable DIN rail following local electrical regulations and wiring standards. Connect incoming three-phase supply conductors to the input terminals and load conductors to the output terminals, ensuring correct tightening torque for secure connections. Verify the breaker rating matches the protected circuit’s conductor and load requirements. After installation, switch the device on and test the circuit under normal load conditions. Periodically inspect terminal tightness and check for signs of overheating or mechanical damage.

Usage recommendations

Use this breaker as part of a coordinated protection scheme; select complementary upstream and downstream protective devices to ensure selective tripping where required. Do not exceed the rated current and observe the specified breaking capacity relative to the installation prospective short-circuit current. For motor circuits, confirm the inrush current is compatible with a type C characteristic or consider a different tripping characteristic if higher starting currents are expected.
