Description

Square D LA molded case circuit breakers provide thermal magnetic protection. Their primary function is automatic opening of a circuit under overload or short circuit conditions or manual opening. LA circuit breakers contain thermal (overload) and magnetic (short circuit) sensing elements in each pole. Push-to-Trip allows the circuit breaker to be manually tripped without exposure to live parts. This Square D LA molded case circuit breaker is a 3 pole unit mount breaker, 350A and 600VAC. The thermal magnetic circuit breaker has an interrupting rating of 22kA for 600VAC and 10kA for 250VDC. The circuit breaker 1021 suffix indicates a factory installed shunt trip. LA breakers are UL 489, CSA, IEC certified.
