SHMD69800AG - 800Amp Circuit Breaker

SHMD69800AG - 800Amp Circuit Breaker

When you need a dependable replacement for an existing power distribution system, the SHMD69800AG molded case circuit breaker delivers the form, fit, and functionality required for compatible installations. Built on the SMD800A frame, this 800 amp, 3-pole thermal magnetic circuit breaker is designed to help protect electrical systems from overloads, short circuits, and ground faults while giving maintenance professionals the flexibility to fine-tune protection settings for their specific application.

One feature that sets this breaker apart is its adjustable trip unit, allowing users to customize important protection parameters including continuous current setting, long-time delay, instantaneous setting, ground fault pickup, and ground fault delay. These adjustments can help support proper coordination throughout a power distribution system while matching the operating requirements of connected equipment. With interrupting ratings of 50kA at 600VAC, 65kA at 480VAC, and 100kA at 240VAC, the SHMD69800AG is commonly used in commercial and industrial electrical systems where maintaining compatibility with existing equipment is essential. Built to last, this breaker is supplied without lug terminals, allowing installers to select compatible lugs separately when needed.
