1PK - Switch

The 1PK - Switch is a rugged fusible switch engineered for reliable on/off isolation and overcurrent protection in demanding industrial and commercial environments. Its compact, maintainable design helps keep power distribution safe and accessible where space is at a premium, without compromising performance.

• Robust construction for harsh environments built to withstand vibration, dust, and temperature variations typical of industrial facilities.
• Reliable isolation and protection provides clear disconnect capability while safeguarding equipment from overload conditions.
• Compact footprint tailored for panelboards and restricted spaces, making it suitable for both new installations and retrofits.
• Maintenance-friendly design simplifies routine servicing and fuse replacements, helping reduce downtime during routine checks or fault conditions.
• Versatile application ideal for motor disconnects and branch circuit protection where a fusible switch is required.

Ideal applications include motor-driven equipment in manufacturing lines, HVAC and pumping systems, and distributed power setups within commercial and industrial facilities. The 1PK - Switch serves as a dependable interface between your power source and critical machinery, ensuring that circuits can be safely opened for service while providing essential overcurrent protection to prevent damage.

How it works in practice — when the circuit is closed, the 1PK - Switch enables power flow to connected equipment. In the event of an overload or fault, the fusible element interrupts current to protect downstream components and wiring, then the switch can be safely opened for maintenance or replacement. This straightforward, hands-on operation supports predictable, low-downtime servicing.

Why choose the 1PK - Switch — a purpose-built solution that combines a compact form factor with dependable isolation and protective features. It’s designed for environments where space, ease of maintenance, and reliable fault protection matter most, reducing downtime and extending the life of connected equipment.

Upgrade your electrical distribution with the 1PK - Switch and experience a proven, maintenance-friendly approach to motor disconnects, panelboard integration, and branch circuit protection in one compact, durable package.
