Magnetic Withstand Circuit Breaker
High performance circuit protection and coordination for mission
critical power applications.
With a history of reliability and performance unequaled in the marketplace, the Square D® LA Circuit Breaker has been specifically upgraded to deliver superior electrical protection for mission critical loads. The new LA High Magnetic Withstand Circuit Breaker, with handle ratings of 200 A, 225 A, 250 A and 400 A, achieves system coordination and selectivity second to none when used in conjunction with Square D QO® circuit breakers.
The superior system of protection helps ensure that only the upstream branch breaker nearest the fault trips to clear the fault, helping to eliminate unnecessary tripping and downtime. The LA High Magnetic Withstand Circuit Breaker is ideal for mission critical loads in hospitals, data centers and industrial environments, or at the machine level.
