Trip System (Trip Units)
The H-frame and J-frame circuit breakers are equipped with a thermal-magnetic trip system designed
to open automatically under overload or short circuit. H-frame and J-frame circuit breakers contain
individual thermal (overload) and magnetic (short circuit) sensing elements in each pole.
The amperage ratings of the thermal trip elements are calibrated at 104°F (40°C) free air ambient
temperature. Per the National Electric Code
continuously at up to 80% of their rating.
100% Rated
Some models of the H- and J-frame circuit breakers are UL Listed to be applied at up to 100% of their
current rating. Because of the additional heat generated, the use of specially-designed enclosures
(defined on page 42) and 90°C rated wire is required when applying circuit breakers at 100% of
continuous current rating. Markings on the circuit breaker indicate the minimum enclosure size and
ventilation required. The 90°C wire must be sized according to the ampacities of the 75°C wire column
in the NEC. Circuit breakers with 100% rating can also be used in applications requiring only 80%
continuous loading.
