SCLD69500G - 500Amp Circuit Breaker

SCLD69500G - 500Amp Circuit Breaker

The Siemens SCLD69500G circuit breaker is a 500-amp, three-pole molded case circuit breaker (MCCB) from the Siemens SENTRON family. Designed for your electrical distribution equipment that requires an LD-frame breaker, this model combines a 600V AC voltage rating, current-limiting breaking capacity, and a SensiTrip electronic trip unit. With an interrupting rating of 100kAIC at 600V AC and 150kAIC at 480V AC, it provides clearly defined specifications for evaluating compatibility with commercial and industrial electrical systems.

Key Features and Benefits
