Airpax UPL00-24381-1 DC Circuit Breaker 2 Pole

Airpax UPL00-24381-1 is a two-pole DC circuit breaker in the Airpax UP family, designed to protect DC power circuits by interrupting fault current. It is specified for a maximum of 65 VDC operational voltage and can carry up to 100 A as a full-load current, with the SW Delay trip option shaping how the device responds to overloads. Built as part of Airpax’s UP/APL family, the breaker uses wide-terminal construction to meet UL and CSA creepage requirements, and every APL/UPL unit is manufactured with stainless-steel springs and plated parts for durability in rugged environments. The two-pole configuration enables protection of two conductors within a single enclosure, simplifying panel layouts and reducing component count in DC distribution schemes. As with Airpax magnetic circuit protectors, the UPL00-24381-1 is intended for reliable interruption when overload or short-circuit conditions arise, providing a predictable, repeatable response that helps safeguard power supplies, motors, and other DC-powered equipment in controlled systems.
