N4-4-1400-S1-DC - 1400A, 4-Pole, Disconnect Switch

The N4-4-1400-S1-DC is a rugged, DC-rated disconnect switch engineered for industrial and commercial electrical rooms where safe isolation and reliable outage management are non‑negotiable. With a 1400A current rating across 4 poles, this switch delivers decisive disconnection under load, making maintenance safer and system downtime more predictable. Built to support strict lockout/tagout procedures, it helps teams stay compliant while keeping personnel and equipment protected during service work.

Key capabilities that set it apart

• 4-pole isolation: completely disconnects all conductors in a single action for thorough circuit isolation and safer maintenance workflows.
• 1400A amperage rating: designed to handle high‑current feeders common in heavy equipment, data centers, and large DC systems.
• DC-ready design: optimized for DC circuits and loads, providing stable switching performance where it’s most needed.
• Lockout/Tagout compatibility: built to integrate with standard LOTO practices, supporting safer, auditable maintenance procedures.
• Reliable under load: engineered to interrupt power cleanly even when circuits are energized, reducing risk during service and startup sequences.
• Durable construction: rugged enclosure and durable internals designed for long service life in demanding environments such as factories, plants, and telecom rooms.

Ideal use scenarios

• Industrial power distribution panels and feeders requiring robust, full-path isolation up to 1400A.
• DC-based infrastructure—data centers, battery storage systems, and telecom cabinets—where safe disconnection is critical.
• Manufacturing lines and automation cells that rely on strict lockout/tagout for safe maintenance windows.
• Facilities seeking a reliable, code-aligned solution for routine maintenance, fault isolation, and energy management.

Why choose the N4-4-1400-S1-DC

This model brings together high current capacity, comprehensive four‑pole isolation, and DC-focused switching performance in a single, purpose-built device. By prioritizing complete circuit disconnection and compatibility with standard safety protocols, it reduces downtime risk and enhances maintenance safety—without compromising on long‑term durability in harsh operating environments.

Installation and maintenance tips

• Adhere to the wiring diagrams and specify compatible lockout devices to support your facility’s safety program.
• Schedule periodic inspections of the enclosure, contacts, and terminations to ensure enduring performance in challenging environments.
• Coordinate with electrical panel design to ensure the 4-pole configuration matches your isolation requirements and busbar layout.
• Document every operation and ensure maintenance personnel are trained on proper disconnection procedures for DC systems.
