Westinghouse DS363R - 100A, 600V, 3-Pole, Disconnect Switch

The Westinghouse DS363R Disconnect Switch is a purpose-built isolation solution for demanding industrial and commercial environments. With a 100A rating and a 600V maximum, this 3-pole switch delivers dependable electrical isolation when it matters most, supporting safe lockout/tagout procedures and reliable disconnection under load for lasting performance.

Key reasons to choose the Westinghouse DS363R:

• Three-pole isolation for complete phase safety — disconnects all three conductors to ensure full de-energization of three-phase systems, reducing arc and re-energization risk during maintenance.
• Strong under-load disconnection — engineered to open the circuit cleanly even when powered, enabling safer servicing without compromising system uptime.
• Lockout/Tagout compatibility — designed to support standard lockout/tagout procedures, helping facilities stay compliant and protect staff during servicing.
• Robust, durable construction — built for long-term durability in busy environments, delivering consistent performance in daily switching operations.
• Versatile electrical ratings — 100A continuous current at up to 600V, adaptable to a wide range of commercial and light industrial installations.
• Simple integration — ideal for mounting in control panels and switchgear assemblies, with straightforward wiring and setup for reliable field use.

Ideal use scenarios include machine isolation on production lines, shutdowns in electrical rooms, and routine maintenance in facilities where safe, rapid de-energization is essential. The DS363R helps facilities managers, plant engineers, and electricians maintain safety standards while minimizing downtime.

What problems does it solve? It provides guaranteed isolation of all live conductors, supports rigorous lockout/tagout practices, and ensures a controlled, safe disconnection under load—helping prevent accidental re-energization and reducing the risk of electrical incidents during servicing.
