SCLD69600NT - 600Amp Circuit Breaker

SCLD69600NT - 600Amp Circuit Breaker

The Siemens SCLD69600NT circuit breaker is a 600-amp, three-pole molded case circuit breaker (MCCB) from the Siemens SENTRON low-voltage product line. Designed for your electrical distribution equipment requiring an LD-frame breaker, this model combines a 600V AC voltage rating, current-limiting breaking-capacity construction, and a SensiTrip LSI electronic trip unit. It is rated 100kAIC at 600V AC and 150kAIC at 480V AC, giving electricians and maintenance professionals the electrical ratings needed to evaluate compatibility with existing commercial and industrial power distribution systems.

Key Features and Benefits
