APC A9F03132 Miniature Circuit Breaker 32A 3P C-Curve 10kA

The APC A9F03132 is a high-performance miniature circuit breaker (MCB) designed for reliable overcurrent and short-circuit protection in electrical installations. With a rated current of 32 A, 3 poles, and a C tripping curve, this MCB is ideal for protecting circuits with moderate inrush currents, such as lighting and motor loads. It offers a breaking capacity of 10 kA at 400 V AC, ensuring robust protection in industrial and commercial environments.

Advantages

This MCB provides reliable protection against overloads and short circuits, with a compact design for easy DIN rail mounting. The C-curve characteristic ensures compatibility with a wide range of loads, while the high breaking capacity guarantees safety under fault conditions. The tunnel-type terminals simplify wiring, and the IP20 front face protection allows safe installation in distribution boards.

Suitable for

• Industrial and commercial electrical panels
• Protection of lighting circuits, motors, and transformers
• Residential distribution boards requiring high breaking capacity
• Applications requiring 3-pole protection up to 32 A
