The Airpax™ IAR/IUR/IER/CUR/CER series hydraulic-magnetic circuit breaker/protector provides a compact and reliable solution for circuit protection in rack mount applications. It offers consistent operation from -40°C to 85°C, with interrupt capacities up to 5,000 AIC at 80VDC and 2,000 AIC at 250VAC. The series trip configuration acts as both a switch and protector, while the mid-trip option provides remote indication of the circuit's status. Approved to UL489A and TÜV standards, the CER series is suitable for both wireless and wired applications.
