INTRODUCTION
The Airpax™ IAR/IUR/IER/CUR/CER series is a snap-acting hydraulic-magnetic circuit breaker / protector that combines power
switching and accurate, reliable circuit protection in one aesthetically pleasing, “1U” or “1RU” sized package.
Designed for rack mount applications, the IAR/IUR/IER/CUR/CER series allows efficient use of rack space without sacrificing
performance via proven hydraulic-magnetic technology that provides consistent operation from -40°C to 85°C, with a circuit interrupt
capacity up to 5,000 AIC at 80VDC and 2,000 AIC at 250VAC. Available in series trip and mid-trip configurations, with auxiliary alarm
switch options to provide monitoring of critical circuits.
The CER series circuit breaker provides the necessary ratings for wireless and wired applications while meeting UL489A and TÜV
requirements for approval.
