It’s engineered to complement lockout/tagout procedures, helping you maintain strict safety standards without compromising uptime.

Key advantages at a glance

• 30A, 3-Pole configuration — clears all three current paths in three-phase circuits for complete, reliable isolation.
• Non-Fusible design — simple to install and maintain, with no internal fuses to replace when servicing equipment.
• NEMA 4X enclosure — built to resist corrosion, dust, and washdown environments, ideal for demanding industrial settings.
• Safe under-load disconnection — maintains performance when switching off equipment that is energized, reducing downtime and risk.
• Lockout/Tagout readiness — supports compliant, verifiable safety procedures during maintenance and service work.

Why the DH361UWK matters for your operation

In facilities with multiple machines and power feeds, reliable disconnection is critical for maintenance, service, and safety audits. The DH361UWK provides a clear, deliberate isolation point that technicians can trust. Its 3-pole arrangement ensures all conductors in a three-phase system are securely disconnected, eliminating partial de-energization risks. The weatherproof, corrosion-resistant NEMA 4X enclosure keeps the switch dependable in environments with moisture, dust, or corrosive exposure, from manufacturing floors to outdoor equipment pits.

Ideal use cases

• Service disconnects for motors, pumps, conveyors, and other three-phase equipment
• Maintenance lockout/tagout points to prevent accidental energization during repairs
• Temporary isolation for testing, troubleshooting, or equipment rearrangement
• Electrical isolation in washdown or harsh industrial environments where enclosure integrity matters

Practical guidance for deployment

• Pair the DH361UWK with your existing lockout devices to create a verifiable safety seal during maintenance.
• Use it as a primary isolation point for three-phase equipment that requires rapid and reliable disconnection without replacing fuses.
• Ensure proper labeling and clear identification of the disconnect location to streamline training and compliance audits.
• Plan mounting and wiring in accordance with applicable electrical codes and the environment where the switch will operate.
