Datasheet BR & SU Series UL489/CSA C22.2 No.5-02 (Branch rated) Circuit Breakers UL1077/CSA C22.2 No.235 Supplementary Protectors NEW Compared to traditional fuse installation, the UL489/CSA C22.2 No.5-02, UL1077/CSA C22.2 No.235 compliant circuit breakers listed here assist with the complex task of selecting correct types and characteristics and offer a less bulky installation solution. Our range of miniature, molded-case circuit breakers, in combination with our accessories for factory or on-site installation, offer enhanced control and monitoring capabilities. Installation kits include all parts and instructions to make the on-site job easy. We supply UL489/CSA C22.2 No.5-02 and UL1077/CSA C22.2 No.235 compliant 1, 2 and 3-pole-type circuit breakers from 0.5 to 60 Ampere and with type C and D characteristics. Attachments such as neutral switches, auxiliary contacts and shunt trips are also available for this system. All accessories for modern busbar installations are available in compliance with the relevant UL standards.
