Westinghouse DS46R - 200A, 3-Pole, Fused Disconnect Switch

Engineered for demanding industrial and commercial settings, the Westinghouse DS46R delivers dependable electrical isolation when it matters most. This 200A, 3-Pole Fused Disconnect Switch combines robust protection with straightforward operation, making it a trusted choice for teams that prioritize safety, reliability, and uptime.

Key strengths of the DS46R include:

• 200A current rating provides ample capacity for demanding loads while preserving quick, decisive disconnection when faults occur.
• Three-pole configuration ensures complete phase isolation in three-phase systems, preventing partial energization and reducing risk during maintenance.
• Fused protection adds an extra layer of circuit safeguarding, helping to limit fault energy and protect downstream equipment.
• Safe lockout/tagout compatibility supports disciplined safety procedures, giving technicians a reliable way to secure power during service and repairs.
• Durable, long-term performance designed to stand up to the rigors of busy electrical rooms and continuous operation, reducing maintenance intervals over time.

Ideal use scenarios include motor feeders, pump circuits, and other three-phase loads in manufacturing floors, processing plants, HVAC systems, and commercial facilities. The DS46R is purpose-built for environments where a reliable, fast-acting disconnect is essential for safe service and minimal downtime. With its fused design and solid Westinghouse heritage, it offers a clear path to safer, more efficient electrical isolation compared with non-fused or non-isolated disconnect options.

Operational benefits you’ll notice in daily practice:

• Simplified maintenance windows via clear, lockable disconnection that protects technicians during servicing.
• Enhanced reliability under load due to fused protection, which helps prevent nuisance outages from minor faults.
• Clear electrical discipline that aligns with safety standards and lockout/tagout protocols, supporting compliant work practices.
• Efficient integration into existing electrical distributions and control gear thanks to its straightforward, three-pole design.

Choosing the Westinghouse DS46R means selecting a purpose-built solution for reliable isolation and protective disconnecting in demanding environments. For facilities prioritizing safety, uptime, and clear fault protection, this 200A, 3-Pole Fused Disconnect Switch stands out as a durable, dependable cornerstone of your electrical safety strategy.
