SCLD69500NGT - 500Amp Circuit Breaker

SCLD69500NGT - 500Amp Circuit Breaker

The Siemens SCLD69500NGT circuit breaker is a 500-amp, three-pole SENTRON molded case circuit breaker (MCCB) for your electrical distribution equipment that requires a specific combination of current rating, frame dimensions, and electronic trip functions. Rated for 600V AC, this Siemens LD-frame breaker features 100kAIC interrupting capacity at 600V AC and 150kAIC at 480V AC. Its current-limiting breaking-capacity construction and standard 40°C breaker designation are part of the manufacturer's specifications, making them important details when evaluating the breaker for compatible commercial and industrial electrical systems.

Key Features and Benefits
