QF26mm Low Rating AC MCB for 230-415VAC 5-63A
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.
Very compact CBI Hydraulic-Magnetic circuit breakers for miniaturized distributions and various applications of equipment protection. The CBI series Q frame consists of modular circuit breakers at rated currents of 0,1-250A. The Q series is available in single, double, triple and four-pole configurations.
Black and Grey
The Q series, with a modular width of 13 mm, is available in two colors – black and grey. Electrical data are the same for both designs. The grey version "Greyline" has a 45 mm front escutcheon, just like standard devices for rail mounting. The 13 mm "Blackline" has a 57 mm front escutcheon that gives the application a professional appearance.
Lack of Space?
Due to the fact that the modular width is 13 mm instead of the traditional 18 mm, you will realize a space saving of more than 30% in the same cabinet size. This is ideal if you are going to upgrade existing Equipment, equally so if you would like to fully optimize and reduce the dimensions on a new design. More compact dimensions are often associated with higher temperatures, but as the Q-range is hydraulic magnetic and thus unaffected ambient temperature, it will always hold rated current. Specially adapted busbars with 13 mm modular width, are available in various configurations.
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.
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.
High DC voltages, like 300-600VDC, is more and more common in power distributions as a way to reduce the amount of copper in cables and busbar systems. Up to now there has been a challenge to find a MCB that in a safe way can handle such high DC voltages. Now the solution to this is the new development from CBI, the Y-series. It is a revolutionary product that is build on the same proven Hydraulic-Magnetic principle like the rest of the CBI products. Meaning that no de-rating is needed due to the ambient temperature. Y-series can handle 300VDC in one 13 mm module and for applications that require 400 or 600 VDC they can be delivered serial connected from factory and is the 2x13 mm wide. If you need to break both plus and minus in your application, the Y-frame can be delivered as a real electrical 2 pole circuit breaker. In that case up to 300 VDC is 2x13mm wide and 301-600 VDC is 2x13 +2x13mm. I.e. total width 52 mm (4x13).
