Airpax CELHPK111-1REC4-32538-1 Circuit Breaker

Airpax CELHPK111-1REC4-32538-1 is a 250 A, three-pole circuit breaker from Sensata-Airpax’s CEL family, built with a magnetic-hydraulic (Mag-Hyd) trip mechanism and a lever-operated handle for manual operation. Identified by the CELHPK111-1REC4-32538-1 part number, this unit provides multi-pole overcurrent protection in a single assembly, making it suitable for close-panel protection where three separate conductors must be interrupted simultaneously. The CEL series is designed to deliver fast magnetic interruption with hydraulic-assisted actuation, offering reliable tripping behavior in protection schemes that require coordination among poles. Typical applications include electrical distribution panels and energy storage system environments where robust, high-current protection on multiple conductors is essential. This model’s 3-pole configuration and 250 A rating distinguish it within the CEL lineup for high-current protection tasks, combining durable Mechanical Lever operation with the proven magnetic-hydraulic trip design used across Airpax CEL devices.
