DH363FRK - 100A, 600V, 3-Pole, Fused Disconnect Switch

Designed for demanding industrial and commercial environments, the DH363FRK Fused Disconnect Switch provides safe, reliable electrical isolation with confidence. With a 100A rating at 600V and a 3-Pole configuration, it delivers definitive disconnection of all phases under load, making maintenance, testing, and startup safer and faster. The built-in fused design adds a layer of overcurrent protection, supporting effective protection for motors and downstream equipment while you execute lockout/tagout procedures.

Why choose the DH363FRK?

• Three-pole isolation: Ensures all live lines open together, preventing any residual energization during service.
• Integrated fusing: Provides overcurrent protection on each leg, helping to guard against short circuits and overloads.
• Rugged reliability: Built to withstand industrial environments, delivering consistent performance over the long term.
• Lockout/tagout readiness: Designed to fit into standard maintenance safety workflows, simplifying compliant isolation during servicing.
