Airpax IEGH666-1REC4-63F-2.50-91-V Circuit Breaker

Airpax Sensata IEGH666-1REC4-63F-2.50-91-V circuit breaker is a compact protection device designed to interrupt current in electrical circuits and protect wiring from overloads. The model encodes a 2.50 A rating and a 91-V variant, with the 63F designation indicating a motor-start/short-delay trip characteristic that can include inertial delay when modified by an F suffix. As part of the IEGH666-1REC4 family, this device is UL489-listed and intended for 50/60 Hz systems; the H in the designation signals a handle-operated form factor suitable for manual reset and isolation in control panels. Designed for use in low‑voltage applications around the 90 V range, this Airpax breaker integrates with standard termination configurations and mounting footprints, delivering reliable protection for small circuits and motor‑control wiring. This exact part number variant—63F-2.50-91-V—helps specify your protection requirements precisely when matching replacement parts or upgrading existing equipment.
