Disconnect Switches
Safe Circuit Isolation for Industrial Motor Controls & Machinery
Ensure the safety of your personnel and equipment with high-quality industrial disconnect switches from Kent Electrical Supply. Our selection of load break switches and safety disconnects provides a reliable mechanical means to isolate electrical circuits during maintenance, repair, or emergency stop situations. Whether you need a compact 16A rotary switch or a heavy-duty 100A enclosed isolator, we stock the parts you need for immediate dispatch.
Shop Leading Brands: Moeller, Lovato & More
We specialize in motor control disconnects from the world's most trusted manufacturers. Our inventory includes:
- Moeller Electric (Eaton): A full range of P1 and P3 series disconnects, including the P1-25 and P3-100 models, known for their modularity and rugged performance.
- Lovato Electric: Featuring the GA series direct-operating and door-coupling switches (GA016A to GA125A).
- Schneider Electric & Siemens: Reliable isolation solutions for standard North American and IEC-compliant control panels.
- LS Industrial: High-performance switches designed for global industrial applications.
Fused vs. Non-Fused Disconnect Switches
Choosing the right protection level is critical for your electrical system’s coordination:
- Non-Fused Disconnects: Ideal for applications where upstream circuit breakers already provide overcurrent protection. These switches offer a cost-effective, compact solution for local equipment isolation.
- Fused (Fusible) Disconnects: Combining a manual switch with integrated fuse holders, these units provide both a visible air-gap isolation and dedicated short-circuit protection in a single device—perfect for high-fault environments.
Key Features & Configurations
Our disconnect switches are engineered to meet strict industrial standards (UL 508, UL 98, and IEC 60947-3):
- Mounting Styles: Choose from door-mounted (cover mount), base-mounted (DIN rail), or surface-mounted enclosed units.
- Handle Options: Available with standard black handles or red/yellow emergency stop handles. Most models feature padlockable designs for Lockout/Tagout (LOTO) compliance.
- Enclosure Ratings: We stock NEMA 3R, NEMA 4, and NEMA 12 (IP65) rated enclosures to protect your switches in wash-down, outdoor, or dusty industrial environments.
- Accessories: Complete your build with auxiliary contacts, replacement handles, and shaft extensions.
