The QZ Series of UL1077/ CSA C22.2 No. 235 recognized high density supplementary circuit breakers are only 13 mm wide, which frees up more than 25% of DIN rail space compared to standard density circuit protection devices. Not only is this a compact option, but these hydraulic magnetic circuit breakers offer a range of products featuring a 0.5 low amp circuit breaker up to 60 amp circuit breaker. They are DIN rail mounted, 1, 2 or 3 pole, 5kA interrupt capacity and operate on a standard #2 trip curve.
