QT26mm DC MCB for up to 80VDC 70-250A

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.
