LK4DU3CN - 30A, Disconnect Switch

Meet the LK4DU3CN - 30A, Disconnect Switch: a rugged, industrial-grade disconnect designed for dependable on/off isolation and built-in overcurrent protection in demanding commercial and industrial settings. Its compact footprint and maintainable fusible switch design make it a practical choice where space is at a premium and uptime matters.

Why this 30A disconnect stands out

Engineered for reliability, the LK4DU3CN delivers clean, decisive isolation of circuits with a focus on safe operation and straightforward servicing. The 30A rating provides clear protection for smaller motor loads, control circuits, and branch circuits, while the fusible switch approach adds an extra layer of overcurrent protection without complicating wiring or maintenance.

Key advantages

• Compact and maintainable design: fits into crowded panels and narrow enclosures, with accessible components to simplify routine checks and fuse replacement.
• Reliable isolation: ensures circuits can be safely de-energized for service, maintenance, or emergency shutdowns.
• Integrated overcurrent protection: the fusible switch configuration provides targeted protection for connected loads, helping prevent damage from fault conditions.
• Versatile mounting for industrial applications: suitable for motor disconnects, panelboards, and branch circuits where a compact disconnect is required.

Ideal use cases

• Motor disconnect points in compact equipment or small-to-mid size systems
• Isolation devices for panelboards serving feeder or branch circuits
• Protection and control points in commercial environments with tight installation spaces
