• Positive under-load disconnection capability helps ensure safe servicing even when equipment is energized or hot-tapped.
• Durable, purpose-built design tailored for harsh industrial and commercial environments where reliability matters.

Ideal applications

• Motor control centers and large conveyors where dependable isolation is critical
• Industrial pumps, fans, and compressors that require safe service access
• Service panels and equipment enclosures in manufacturing facilities, processing plants, and packaging lines

Why this disconnect switch matters

The 1494F-D100 isn’t just about breaking the circuit—it’s about enabling safer maintenance workflows. By providing a clear, mechanical disconnect with lockout/tagout support, it helps facilities meet safety standards, reduce arc-flash risk during servicing, and minimize downtime caused by unplanned energization. Three-phase isolation also improves equipment protection during switching events, safeguarding both operators and the system itself.

Installation and operation tips

• Install in a suitable electrical enclosure or panel that accommodates a 3-pole disconnect and follows local electrical codes.
• Connect the supply lines to the input terminals and the load lines to the output terminals according to the equipment layout and wiring diagrams.
• When servicing, apply a lock and tag across the handle to secure the switch in the OFF position and prevent accidental re-energization.
• Operate the handle to ON or OFF as part of routine system commissioning, maintenance, or emergency procedures, ensuring a full, deliberate action.

Maintenance and longevity

Regular inspection of the disconnect’s mechanical action and terminal connections helps maintain peak performance. Check for any signs of corrosion, looseness, or wear on the handle and conductors, and address issues promptly to preserve safe isolation and reliable operation over time.
