Airpax IELH1111-1-63F-25.0-E-01 Circuit Breaker

Airpax IELH1111-1-63F-25.0-E-01 Circuit Breaker is a hydraulic-magnetic, four-pole protective device from Airpax (Sensata) rated for 25 A on AC circuits up to 480 V, with 277/480 V applications typical in commercial and industrial panels. The IELH11 family uses hydraulic-magnetic actuation to deliver reliable overcurrent protection with fast trip response and tolerance to brief transient faults, making it suitable for motor protection and multi-line distribution panels. Related catalog entries for the same product line (such as IELH11-1-63F-25.0-01-V and IELHK11-1-63F-25.0-D-01-V) appear across major distributors, indicating a consistent 25 A, four-pole configuration and variations in suffixes that reflect mounting and packaging options, including panel-mount configurations. Applications include protection of motors, transformers, and other industrial equipment in panel boards and control cabinets, where a common-trip, four-pole device helps ensure coordinated shutdown across multiple conductors during a fault.
