Description
LJA36400U44X - Schneider Electric - I-Line Plug-In 400 Amp 3 Pole 600 Volt Square D Molded Case Circuit Breaker
PowerPacT L-Frame circuit breakers are designed to protect electrical systems from damage caused by overloads and short circuits. PowerPacT L-Frame circuit breakers are available with electronic trip units. All PowerPacT L-Frame circuit breakers are equipped with dual-break rotating contacts that reduce the amount of peak current during a short circuit fault. All PowerPacT circuit breakers have an integral push-to-trip button in the cover to manually trip the circuit breaker. PowerPacT L circuit breakers are available in 3 and 4-pole unit mount, I-Line, and drawout constructions. This PowerPacT L, 400A, 3 pole, circuit breaker has an interrupting rating of 25kA at 600VAC. This circuit breaker provides MicroLogic Ammeter with a 6.3A trip unit and an LSIG function. This unit has I-Line terminations on the line side and mechanical lugs on the load side. This circuit breaker has a continuous current rating of 80% with an ABC phase connection. PowerPacT L circuit breakers comply to UL, CSA, NOM, and IEC standards and are CE marked.
