SHND69120ANT - 1200Amp Circuit Breaker

SHND69120ANT - 1200Amp Circuit Breaker

When your electrical distribution system calls for a 1200-amp molded-case circuit breaker, the SHND69120ANT provides the ratings and adjustable protection needed for many commercial and industrial applications. Built on the SND 1200A frame, this 3-pole thermal-magnetic circuit breaker is designed as a form, fit, and function replacement for compatible equipment, making it a practical choice for maintaining or servicing existing power distribution systems. One feature that makes this breaker especially versatile is its adjustable trip unit. Instead of relying on fixed protection settings, users can tailor the breaker's operation to match the needs of their electrical system through adjustable continuous current, long-time delay, instantaneous, short-time pickup, short-time delay, and short-time I²t pickup settings. This added flexibility helps support proper coordination with other protective devices while maintaining dependable overcurrent and short-circuit protection. With interrupting ratings of 50 kA at 600 VAC, 65 kA at 480 VAC, and 100 kA at 240 VAC, the SHND69120ANT is suitable for a wide range of high-capacity power distribution applications. Built to last, this breaker is commonly used in switchboards, panelboards, industrial facilities, and other electrical systems where a 1200A, 3-pole thermal-magnetic molded-case circuit breaker is required.
