SCLD69500NT - 500Amp Circuit Breaker

SCLD69500NT - 500Amp Circuit Breaker

The Siemens SCLD69500NT circuit breaker is a 500-amp, 3-pole molded case circuit breaker (MCCB) designed for use in your compatible low-voltage electrical distribution equipment. Part of the Siemens SENTRON family, this LD-frame breaker combines a 600V AC voltage rating, a 100kAIC interrupting capacity at 600V AC, and a SensiTrip electronic trip unit with long-time, short-time, and instantaneous (LSI) protection functions. For electrical contractors, facility maintenance teams, and equipment owners working with existing Siemens systems, the SCLD69500NT provides clear specifications to evaluate an exact form, fit, and functional replacement.

Key Features and Benefits
