SCLD69600NGT - 600Amp Circuit Breaker

SCLD69600NGT - 600Amp Circuit Breaker

The Siemens SCLD69600NGT 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 systems requiring an LD-frame breaker, this model features a 600V AC voltage rating, current-limiting breaking-capacity construction, and a SensiTrip LSIG electronic trip unit. With an interrupting rating of 100kAIC at 600V AC and 150kAIC at 480V AC, it provides clear electrical characteristics to evaluate compatibility with existing commercial and industrial equipment.

Key Features and Benefits

• 600-Amp Current Rating: Provides a defined 600A breaker rating for electrical distribution applications requiring this current capacity.
• Three-Pole Configuration: Designed for compatible three-phase electrical systems that require a three-pole molded-case circuit breaker.
• 600V AC Voltage Rating: Suitable for consideration in systems operating within the manufacturer's specified voltage rating.
• LD-Frame Design: Provides a specific frame configuration for evaluating form and fit in compatible existing electrical equipment.
• SensiTrip Electronic Trip Unit: Incorporates Siemens electronic trip technology with the LSIG functions identified for this catalog number.
