Airpax Electronics 229-2-0-SW-8-4-3 Circuit Breaker

Airpax Electronics 229-2-0-SW-8-4-3 is a two-pole circuit breaker from the Sensata-Airpax family, designed to interrupt current in electrical panels and equipment when an overcurrent occurs. The device carries a 3 A current rating and is specified for operation up to 480 V in a 2P configuration, aligning with the 229 family’s role as a magnetic circuit protector. In Airpax’s product literature, the 229 series is described as magnetic circuit protectors with UL recognition as a Supplementary Protector under UL 1077, which speaks to its intended use in protecting circuits that require reliable protection without full disconnect isolation. This model is engineered to provide a fast trip response to overcurrent events while preserving a compact form factor suitable for panel interiors and control cabinets where space is limited.
