ABB Stotz-Kontakt 1SAM340010R1001 MS132-0.16KT transformer circuit breaker

Transformer circuit breaker MS132-KT in screwless push-in spring connection technology with thermal and electromagnetic protection represents the compact and powerful series with high short-circuit breaking capacity for transformer protection up to 25 A with a module width of 45 mm. With this device, the primary-side transformer rated current is thermally monitored by setting the current scale. The short-circuit is triggered when 20 times the device rated current occurs. The temperature-compensated device has a rotary handle operation with a clear switch position indicator I/TRIP/0. MS132-KT also has a short-circuit indicator. The rotary handle can be locked directly in the 0 position using a padlock. Auxiliary, signal and short-circuit signaling contacts as well as undervoltage and shunt current releases can be installed without tools. Push-in spring variants are available for auxiliary and signal contacts; these also fit the transformer circuit breakers with screw technology. The push-in spring connection terminals allow tool-free and time-saving insertion of the connecting cables for rigid wires and stranded wires with wire end ferrules. Stranded wires without wire end ferrules can also be connected, eliminating the need for subsequent readjustment of the connections.
