Cutler-Hammer TAP321RN - 30A, 240V, Fusible, Switch

Meet the Cutler-Hammer TAP321RN — a 30A, 240V fusible switch engineered for dependable on/off isolation and built-in overcurrent protection in demanding industrial and commercial settings. This compact, maintainable switch is purpose-built for motor disconnects, panelboards, and branch circuits where safety, reliability, and space efficiency matter most.

Why choose the TAP321RN? It combines a rugged switching mechanism with fusible protection in a single, streamlined unit. That means you get immediate electrical isolation for service or safety tasks, plus inherent protection for wiring and equipment against overcurrent events, without needing separate protective devices.

Key features and benefits

• Compact 30A, 240V design suited for tight enclosures and spaces where larger disconnects won’t fit, while still delivering reliable performance for common industrial loads.
• Fusible protection provides integrated overcurrent protection, reducing the number of components in your electrical distribution and simplifying installation and maintenance workflows.
• Dedicated for motor disconnects and as a protective link in panelboards and branch circuits, helping to streamline control schemes and improve safety in your electrical system.
• Rugged, application-ready construction designed to withstand the rigors of busy industrial and commercial environments where switches are cycled and serviced regularly.
• Clear isolation and serviceability enables quick, safe shutdowns for maintenance, inspections, or emergency response without compromising downstream protection.

Practical use cases

In a manufacturing line, replace a generic disconnect with the TAP321RN to provide immediate, reliable isolation during maintenance while protecting conductors and equipment from faults. In control panels, deploy it as a central motor disconnect or as the protective link for critical branch circuits, ensuring you have a robust fail-safe that’s easy to service.

What sets it apart from other disconnects

With the TAP321RN, you don’t have to juggle separate switches and fuses. The fused switch concept simplifies wiring diagrams, reduces component count, and delivers a cohesive protective solution that aligns with practical maintenance workflows. Its 240V, 30A rating covers a broad range of common industrial loads, making it a versatile choice for new installations or panel reworks where space and reliability are priorities.

Tips for selecting and installation

Ensure your enclosure supports a 30A, 240V fused switch and plan for straightforward fuse replacement and access during routine maintenance. Confirm that the TAP321RN’s mounting footprint aligns with your panelboard or disconnect enclosure, and integrate it into your control scheme where immediate isolation and built-in protection improve safety and uptime.
