Airpax 219-1-29478-1 Molded Case Circuit Breaker

Airpax 219-1-29478-1 is a molded case circuit breaker designed for single-pole protection in electrical installations that use 240 V circuits. It is rated to carry 100 A and can interrupt fault currents up to its rating, helping safeguard conductors and devices from overcurrent conditions. The 1P designation indicates a single electrical pole, making it suitable for single-phase 240 V applications where compact protection is required within a panel or distribution board. Identifying the exact Airpax part number 219-1-29478-1 helps ensure compatibility with compatible enclosures and replacement parts in systems designed to accept this specific model. When selecting a replacement, confirm the device’s ratings and footprint match the existing breaker slot in your panel, as using an incompatible rating can affect protective coordination and safety. Molded-case breakers like this are built to interrupt current while fitting into standard panel or equipment enclosures. Use this model when a 100 A, 240 V, single-pole protection device aligns with your circuit's rating and the enclosure's mounting footprint.
