1494U-J30-C4-N - 30A, 600V, 3-Pole, Fusible, Disconnect Switch

The 1494U-J30-C4-N Fusible Disconnect Switch is built for reliability in demanding industrial and commercial environments. This compact, maintainable unit delivers immediate on/off isolation combined with fusible protection, helping you safeguard motors, panels, and branch circuits while minimizing downtime.

Key benefits that matter on the floor

• 3-Pole isolation ensures all three phases are simultaneously disconnected for safe maintenance and fault clearance.
• Fusible protection provides dependable overcurrent interruption, helping protect motors and downstream equipment from damaging arc faults or short circuits.
• 30A at 600V rating covers the common motor loads and branch circuits found in light to medium industrial applications.
• Compact, maintainable design is ideal where space is at a premium and fuse replacement or servicing must be straightforward.
• Versatile application specifically suited for motor disconnects, panelboards, and branch circuit protection in both new builds and service upgrades.

Ideal applications

• Motor disconnects on production lines, conveyors, and HVAC equipment
• Panelboard protection where predictable, easy-to-replace fusible elements are preferred
• Branch circuit protection in control panels and equipment enclosures
• Spaces with limited room where a compact protective switch is advantageous

How it works

The 1494U-J30-C4-N integrates a robust fusible disconnect mechanism with a three-pole contact arrangement. When you need to isolate power for maintenance or in response to an overcurrent event, you simply switch to the off position to completely de-energize the protected circuit. If a fault occurs, the fusible element interrupts the current, helping prevent damage to the motor and downstream protections. When the issue is resolved, replace the fuse and re-energize to restore operation with a clear separation between power and service access.

Practical tips for top performance

• Install in accordance with local electrical codes and ensure proper fuse type and rating for your specific motor load.
• Keep spare fusible elements on hand and follow manufacturer guidelines for replacement intervals to minimize downtime.
• Pair this disconnect with appropriate breaker or protection coordination in the upstream and downstream circuitry to optimize protection and selectivity.
• Use in environments where quick, straightforward maintenance access helps technicians service the switch and fuse elements without extensive downtime.
