ABB MS132-12B

MS132-B represents the compact and powerful series with a width of 45 mm for motor protection up to 15 kW (400 V) in railway applications. The devices meet current railway standards and are therefore suitable for installation in passenger areas and driver's cabins of trains that frequently operate in tunnels and underground. They provide reliable protection in case of overload and short circuit and have a disconnection function. Operation is via a rotary handle with a clear switching position indicator I/TRIP/0, and MS132-B also features a short circuit indicator. The rotary handle can be locked in the 0 position using a padlock. Auxiliary, signal, and short circuit monitoring contacts, as well as undervoltage and operating current triggers, can be mounted without tools; this accessory is also compatible with MS165-B. Three-phase rails for 65 A or 100 A and feed blocks for 25 mm² or 35 mm² allow for the common feeding of multiple motor protection switches. Protective housings and accessories for cabinet and door installation complete the range. MS132-B has a tripping class of 10, is temperature compensated, and is sensitive to phase failure. They comply with international railway standards IEC 60077 in the applicable parts, IEC 61373 (Category 1, Class B) for shock and vibration, as well as the European safety standard EN 45545-2 for fire and smoke.
