N14-0-S400-2NYA - 400A, 700V, Disconnect Switch

The N14-0-S400-2NYA Disconnect Switch is built for safer, more reliable electrical isolation in demanding industrial and commercial settings. With a 400 A rating and a 700 V maximum, it delivers a clean, decisive disconnect that supports standard lockout/tagout procedures and minimizes downtime during maintenance.

Engineered to perform under load, this switch provides dependable disconnection when circuits are energized, helping protect technicians and equipment alike. Its rugged construction is designed for long-term durability in environments marked by vibration, dust, and temperature swings typical of manufacturing floors, utility rooms, and process plants.

• High-current capability: 400 A electrical disconnect capability lets you isolate large equipment without juggling multiple devices.
• Voltage protection: 700 V rating supports safe operation across higher-voltage applications.
• Safe isolation under load: ensures a complete disconnection, reducing arcing and wear on contacts during maintenance.
• Lockout/Tagout readiness: designed to integrate with standard lockout devices, enabling compliant and secure servicing.
• Rugged durability: built to endure demanding industrial conditions for extended service life.
• Versatile integration: suitable for installation in electrical enclosures, motor control centers, and distribution panels.

Use cases include shutting down conveyor systems for routine maintenance, isolating pumps and mixers in process lines, and providing a safe maintenance point in panel and MCC installations. The N14-0-S400-2NYA stands out from simpler disconnects by delivering true isolation under load, which minimizes the risk of residual current during servicing and helps you meet safety protocols more reliably.

Practical tips for optimal performance:

• Pair the switch with your standard lockout/tagout procedures to ensure a compliant and traceable shutdown process.
• Plan wiring and enclosure layout to simplify future maintenance and minimize exposure to energized components.
• Regularly inspect contacts and mounting hardware for signs of wear or corrosion, and follow your maintenance schedule to sustain long-term reliability.
