A circuit breaker for mounting on 35 mm DIN rail, 35×7.5 and 35×15 according to DIN EN 50022. The device requires no setting correction in a wayside cabinet operating across the full annual temperature range. One-, two- and three-pole versions are available, rated 0.5–63 A at up to 110 V DC, 220 V DC with two poles, 240 V AC and 415 V AC. Rated interrupting capacity is up to 10,000 A at 80 and 110 V DC and 6000 A at 240 V AC; at 415 V AC it is 6000 A for two poles up to 25 A and 3000 A for two- or three-pole versions up to 50 A. Frequency is 50/60/400 Hz.
The handle indicates a trip by moving to an intermediate position. Auxiliary and alarm contacts are available-the position-contact terminals are on the load side, while the alarm-contact terminals are on the supply side.
