Product Data Sheet
The PowerPact L-frame circuit breakers are designed to protect electrical systems from damage caused by overloads and short circuits. L-frame circuit breakers are available with Micrologic electronic trip units only. The new generation PowerPact with Micrologic circuit breakers set the standard with direct access to energy management. Integrated metering enhances their protective functions. For the first time, Schneider Electric™ users can monitor energy from 15 to 3000A, offering new performance in a remarkably compact device. Electronic trip units provide highly accurate protection with wide setting ranges and can integrate measurement, metering and communication functions. They can be combined with the front display module (FDM121) to provide functions similar to a power meter. This 3-pole circuit breaker has a 400A rated current. This breaker has a breaking capacity of 10 kA@250VDC operation voltage. This breaker has a thermal-magnetic trip technology. The dimensions are 11 in (H), 6 in (W), 5.84 in (D).
