27DC4021 - 250A, 1000V, Disconnect Switch

The 27DC4021 is a robust Disconnect Switch engineered for demanding industrial and commercial power environments that demand safe, reliable electrical isolation. With a 250A amperage rating and a 1000V voltage rating, it provides a decisive, clean break in power, enabling maintenance, testing, and system changes without compromising safety or uptime.

Designed to support proper lockout/tagout (LOTO) procedures, the 27DC4021 helps protect workers during service by allowing circuits to be securely isolated and kept de-energized. It delivers dependable disconnection under load, reducing the risk of accidental energization when work is being performed on energized equipment. This combination of LOTO readiness and reliable performance makes it a trusted choice for safety-conscious facilities.

Built for long-term durability, this switch stands up to the rigors of busy environments—from manufacturing floors to commercial power rooms. It’s engineered to maintain consistent isolation over time, providing peace of mind that when you need to isolate a circuit, the path remains clearly open and safe for maintenance or modification tasks.
