ABB 1SAM360000R1003 MO132-0.4 0.4A 3P 100kA Motor Protection Circuit-Breaker

The ABB MO132-0.4 (SKU: 1SAM360000R1003) is a 3-pole magnetic-only motor protection circuit-breaker rated at 0.4 A with an exceptional breaking capacity of 100 kA at 400 V AC. Designed for the MO132 series, this compact 45 mm wide device provides reliable short-circuit protection for low-current motor applications in industrial control panels and automation systems. Its magnetic-only trip mechanism ensures instantaneous protection without thermal delay, making it ideal for applications where external overload protection is already provided.
