Airpax IDLHK11-224-43 Electrical Circuit Breaker Switch

Airpax Sensata IDLHK11-224-43 is a magnetic-hydraulic lever-type circuit breaker designed for panel mounting in electrical enclosures. The 42 A device is rated for 250 V and supports operation at both 50 and 60 Hz, making it suitable for a range of international installations; it is part of Sensata-Airpax’s IDL family and carries the part number IDLHK11-224-43. Described as a Mag-Hydraulic Lever breaker, it uses a magnetic trip for instantaneous protection plus a hydraulic delay to handle short-term overloads, delivering reliable fault clearances while minimizing nuisance trips. The unit is configured for AC/DC use via a panel-mount lever design, enabling integration into equipment that requires robust overcurrent protection across varying power architectures. Designed for panel mounting with a lever-operated handle, this device is typically employed to protect feeders, motors, and control circuits within industrial equipment or commercial machinery where a 42 A protection threshold is appropriate and space-conscious panel installations are needed.
