Description
The PowerPact™ H-, J-, and 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 amperage ratings of the thermal trip elements are calibrated at 104°F (40°C) free air ambient temperature. Circuit breakers rated for 100% operation are available but require specially-designed enclosures and 194°F (90°C) rated wire. Devices with the MICROLOGIC electronic trip unit provide adjustable protection settings for greater system flexibility In addition to electronic protection, MICROLOGIC trip units allow users to monitor both energy and power. PowerPact H-, J-, and L-frame circuit breakers offer high performance and a wide range of interchangeable trip units to protect most applications. Electronic trip units provide highly accurate protection with wide setting ranges and can integrate measurement, metering and communication functions. This PowerPact L, circuit breaker has a rated current of 400A and is a 3-pole. This breaker has a breaking capacity of 65 kA@480 VAC and a continuous current of 80 %. This circuit breaker has an electronic trip unit technology with a MICROLOGIC 3.2 S trip unit. This breaker complies to UL & CSA standards. Dimensions for this product are 14.7 in (H), 5.94 in (W), 6.61 in (D). This product comes with an 18 month warranty.
