GACIA N8BH 10kA C 3P 32A Miniature Circuit Breaker MCB

The GACIA N8BH is a high-performance miniature circuit breaker (MCB) designed for overload and short-circuit protection in commercial and industrial electrical installations. With a rated current of 32 A and a C-curve tripping characteristic, it ensures reliable protection for circuits with moderate inrush currents, such as lighting and motor loads. The three-pole configuration (3P) provides simultaneous disconnection of all phases, enhancing safety and system integrity.

Advantages

This MCB offers a high breaking capacity of 10 kA, ensuring robust protection even in high-fault-current environments. Its compact DIN-rail mounting design saves space in distribution boards, while the clear ON/OFF position indicator simplifies maintenance and troubleshooting. The screw terminals accommodate conductors up to 35 mm², making installation straightforward and secure.

Suitable for

• Commercial buildings (offices, retail, schools)
• Industrial control panels and machinery
• Residential distribution boards requiring high breaking capacity
• Lighting and socket-outlet circuits with moderate inrush currents
