TR11-D-X-63-BB-2-N-5.0A is a UL1077 recognized supplementary protector/circuit breaker designed for equipment protection against overload conditions. This thermal trip-free device features a 5.0A current rating with a rated voltage of 240V AC (50/60Hz) or 50V DC, and offers an initial insulation resistance greater than 100 MO at 500V DC. The circuit breaker provides a dielectric strength of 1.5 kV for one minute and a maximum breaking capacity of 60A AC/DC for ratings above 6.0A. It features wing clip (D type) mounting with 6.3mm terminals in X configuration, a black slider with white trip band, and horizontal slider marking. Common applications include protection of control transformers, UPS systems, power strips, and solenoids.
