Y-series in the 300VDC (and above) version has a permanent magnet to help extinguish the arc which is created inside the circuit breaker when switching a DC voltage. In cases where the application calls for a product which is not polarity sensitive there is a range (YB) without the magnets. Then it operates with 150 VDC in one module and 300VDC with 2 modules in series.
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.
QF26HR is a 26 mm wide circuit breaker for AC usage where you have a need for higher rated current. It is the larger version of QF26LR which goes up to 63A. The difference is that QF26HR has a slightly longer lower body. QF26HR is built with rated current between 70 and 125A
QF26LR is a 26 mm wide circuit breaker for AC usage. It is a natural “big brother” to the 13 mm wide QF13 since QF26LR goes all the way up to 63A.
QF19 is a 19 mm wide circuit breaker for AC usage. QF19 keep rated current regardless of ambient temperature. If you have a challenge with high ambient temperatures in your equipment you can rely on that QF19 always keep the rated current. That means, 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.
QF18 is an 18 mm wide circuit breaker for AC use. QF18 maintains its rated current regardless of ambient temperature. If you are experiencing issues with high ambient temperatures in your equipment, you can rest assured that QF18 will always maintain its rated current, meaning no de-rating is needed. It is also developed and certified to handle 100% of the rated current.
The QY13 is a circuit breaker developed for DC applications. Safely interrupting a DC voltage places different demands on the breaker compared to interrupting an AC voltage. The QY series is therefore a dedicated DC breaker with appropriate labeling and certifications.
QZ13 is a circuit breaker designed for AC applications. It has two unique features compared to traditional thermal circuit breakers.
QL13 is an automatic circuit breaker designed for AC use. It has two unique features compared to traditional thermal circuit breakers.
QF13 is a circuit breaker designed for AC applications. It has two unique features compared to traditional thermal circuit breakers.
