Siemens SHLD6B600LSIG Molded Case Circuit Breaker

Siemens SHLD6B600LSIG is a three-pole molded-case circuit breaker (MCCB) from the Sentron family, equipped with an LSIG electronic trip unit (Sensitrip IV) that provides long-time, short-time and instantaneous protection for three-phase circuits. It is rated for 600 A at 600 V AC and protects feeders, motors, and panelboards in industrial and commercial power-distribution systems, integrating with Siemens protection architectures and other Sentron components to enable coordinated protection across a panel. Typical applications include motor feeders, main distribution panels, and branch circuits in manufacturing facilities, data centers, and large commercial buildings, where a compact, reliable 3P 600 A 600 V MCCB with LSIG trip helps ensure fast fault clearance and downstream equipment protection.
