Square D LJA36400CU31X PowerPact L Circuit Breaker, 400A, 3 Pole, 600VAC, 25kA

The Square D PowerPact™L-frame circuit breaker is designed to protect electrical systems from damage caused by overloads and short circuits for distribution systems supplied by transformers and distribution systems supplied by engine generator sets. This 3 poles, 400A, 600 VAC i-line circuit breaker with breaking capacity of 25 kA equipped with Micrologic 3.2 standard trip unit which offers adjustable protection settings for greater system flexibility type as well as communication capability. This L-Frame Mission Critical circuit breaker delivers high levels of selective coordination in a flexible design that can be easily configured for a variety of applications. Tested to be selectively coordinated with the QO™ family of miniature circuit breakers and the ED, EG, and EJ circuit breakers, this solution provides peace of mind when power availability is critical. Using Micrologic trip unit sensors and intelligence, PowerPact L-frame circuit breaker provides access to measurements of all the main electrical parameters on the built-in screen, on a dedicated front display module (FDM121) or through the communication. Through direct access to in-depth information and networking using open protocols, PowerPact L-frame circuit breaker with Micrologic trip unit lets operators optimize the management of electrical installations. Far more than just a circuit breaker, this device is a measurement and communication tool ready to meet energy-efficiency needs through optimized power requirements, increased energy availability, and improved installation management. The PowerPact L-frame circuit breaker is compliant with international standards IEC 60947-2 and UL 508/CSA 22.2 N°14, with UL 489.
