SHMD69800A - 800Amp Circuit Breaker

SHMD69800A - 800Amp Circuit Breaker

When your electrical distribution system calls for dependable 800 amp overcurrent protection, the SHMD69800A molded case circuit breaker delivers the form, fit, and function needed for compatible installations. Built on the SMD800A frame, this 3-pole thermal magnetic circuit breaker is designed for commercial and industrial power distribution applications where protecting equipment from overloads and short circuits is essential.

One feature that sets this breaker apart is its adjustable trip unit, giving qualified personnel the flexibility to fine-tune the continuous current setting, long-time delay, and instantaneous trip functions to better coordinate with the needs of the electrical system. Whether you're replacing an existing breaker during maintenance or keeping critical equipment operating in a compatible legacy system, the SHMD69800A is built to provide dependable protection and long-lasting service.

With interrupting ratings of 50kA at 600VAC, 65kA at 480VAC, and 100kA at 240VAC, this breaker is suitable for installations where higher available fault current is present. Before installation, keep in mind that lug terminals are not included, allowing installers to use the appropriate terminals required for their specific application.
