SCLD69600 - 600Amp Circuit Breaker

SCLD69600 - 600Amp Circuit Breaker

The Siemens SCLD69600 is a 600-amp, three-pole molded-case circuit breaker from the Siemens SENTRON family, designed for electrical distribution equipment that requires an LD-frame breaker with SensiTrip electronic protection. Rated for 600V AC and featuring a 100kAIC interrupting rating at 600V AC, this breaker provides a specific combination of electrical ratings, physical dimensions, and trip functions for compatible installations. Whether you're maintaining an existing switchboard or finding a replacement for an installed breaker, the SCLD69600 provides clear specifications to help you determine whether it's the right match.

Key Features and Benefits

• 600-Amp Current Rating: Designed for electrical distribution applications requiring a 600A molded case circuit breaker, subject to the equipment's approved configuration and electrical design.
• Three-Pole Configuration: Provides three-pole switching and overcurrent protection for compatible three-phase electrical systems.
• 600V AC Voltage Rating: Suitable for evaluation in equipment operating at voltages up to the breaker's specified 600V AC rating.
• Siemens SENTRON Construction: Part of Siemens' low-voltage SENTRON molded case circuit breaker range, with documented electrical and physical specifications.
• LD-Frame Design: Uses the Siemens LD frame, allowing you to compare its dimensions and construction with the requirements of compatible existing equipment.
• SensiTrip Electronic Trip Unit: Incorporates Siemens SensiTrip electronic overcurrent protection with the LI functions specified for this catalog number.
• Long-Time Overcurrent Protection: The long-time trip function protects against sustained overcurrent conditions per the unit's specified characteristics.
• Instantaneous Overcurrent Protection: The instantaneous trip function responds to qualifying high-current fault conditions without an intentional short-time delay.
• Line-Side Lugs Included: Supplied with TA2J6500 line-side lugs to help identify the required terminal arrangement during compatibility checks.
• Load-Side Lugs Included: Also includes TA2J6500 load-side lugs for the manufacturer-specified conductor sizes.
