MS132-0.4 is a manual motor protector designed for single motor protection, group motor installations, and combination motor controller applications. It features a thermal setting range of 0.25 to 0.40 A with a rated operational current of 0.40 A and an instantaneous short-circuit setting of 3.90 A, providing reliable overload protection. The device operates at rated voltages up to 690 V AC and 250 V DC with a trip class of 10, and is suitable for use in self-protected Type E and Type F configurations. With short-circuit breaking capacities of 65 kA at 240V/480V and 47 kA at 600V, the MS132-0.4 is ideal for protecting small motors in industrial control systems, tap conductor protection, and multi-motor installations where compact, manual protection is required.
