Schneider Electric
From $319In stock
Product Description
The Multi9 C60BP miniature circuit breaker provides thermal-magnetic protection for low-voltage distribution applications requiring high inrush tolerance and reliable short-circuit interruption. This 3-pole device is rated 30 A with a D tripping curve, making it suitable for circuits with elevated startup currents. It mounts on DIN rail with a clip-on mechanism and uses a toggle actuator with tunnel terminals for secure copper conductors from 18 to 2 AWG. The breaker achieves a 10 kA interrupting rating at up to 415 VAC per IEC/EN 60947-2 and is UL489 listed at 480Y/277 V, supporting global compliance. It carries IP20/IP40 enclosure ratings and is designed for 50/60 Hz systems. Typical dimensions are 4.06 in H x 2.13 in W x 2.83 in D, with product weight around 0.44 kg. Use it where robust coordination and consistent thermal-magnetic performance are required across commercial OEM panels and multi-standard installations.
