The PowerPacT H-, J-, and L-frame circuit breakers are designed to protect electrical systems from damage caused by overloads and short circuits. H- and J-frame circuit breakers are available with either thermal-magnetic or Micrologic electronic trip units. L-frame circuit breakers are available with Micrologic electronic trip units only. H- and J-frame circuit breakers with thermal-magnetic trip units contain individual thermal (overload) and instantaneous (short circuit) sensing elements in each pole. The amperage ratings of the thermal trip elements are calibrated at 104F (40C) free air ambient temperature. Per the National Electric Code (NEC) and the Canadian Electrical Code, standard circuit breakers may only be applied continuously at up to 80% of their rating. Circuit breakers rated for 100% operation are available but require specially-designed enclosures and 194F (90C) rated wire. Far more than just a circuit breaker, these devices are a measurement and communication tool ready to meet energy-efficiency needs through optimized power requirements, increased energy availability, and improved installation management. This PowerPacT multistandard connection kit is a wiring accessory. This device can be mounted by screws on either the top or bottom. This terminal kit is compatable with PowerPacT H-Frame, PowerPacT J-Frame & PowerPacT L-Frame breakers and come in set of 2.
