The MS132-T transformer protection switch with thermal and electromagnetic protection represents a compact and powerful series with high short-circuit breaking capacity for transformer protection up to 25 A with a module width of 45 mm. In this device, the primary side transformer rated current is thermally monitored by adjusting the current scale. The short-circuit release occurs when the 20-fold device rated current is reached. The temperature-compensated device features a rotary knob operation with a clear switching position indicator I/TRIP/0. Additionally, the MS132-T has a short-circuit indicator. The rotary knob can be directly locked in the 0 position using a padlock. Auxiliary, signal, and short-circuit alarm contacts, as well as under-voltage and operating current releases, can be mounted without tools. Single-phase feed blocks up to 25 mm² and phase connectors support the wiring of single-phase transformers. EAN: 4013614485022.
