QT26mm DC MCB for up to 80VDC 70-250A
QT26 range is approved to IEC60947-2 and UL489A. The range can be delivered with factory fitted trip coil which allows remote switching off.
QT26 range can be delivered from 70A up to 250A. 250A is 2x26mm modules built in parallel and tested to rated current before shipment from factory.
Breaking capacity is 10kA.
Description
QT26 is a 26 mm wide, very robust, circuit breaker for DC usage. Ideal for applications where you need to break higher currents and need a rail mounted product. Just as it’s ”little brother”, QY13, it’s designed to operate DC currents. QT26 keep rated current regardless of ambient temperature. If you have a challenge with high ambient temperatures in your equipment you can rely on that QT26 always keep the rated current. I.e. no de-rating is needed. Like all our Hydraulic-Magnetic circuit breakers it is designed and certified to be loaded at 100% of rated current continuously.
