Key Features – Built for Electricians, Trusted by Installers
01Spring-Reinforced Fuse Clips
Ensures firm, vibration-resistant contact prevents arcing, overheating, and premature failure.
02Quick-Make / Quick-Break Mechanism
Direct-drive operating handle gives crisp, positive ON/OFF indication. Reduces wear on contacts and extends switch life.
03Removable Interior Chassis
Lift out the entire fuse holder assembly for easy wiring, inspection, or replacement - no need to remove the whole box from the wall.
04Ample Gutter Space
Generous internal room for bending wires, adding lugs, or routing conduits without crowding. Meets NEC requirements for wire bending space.
05Multiple Knockout Entries
Pre-stamped holes on top, bottom, sides, and back allow flexible conduit entry from any angle - speeds up installation in tight spaces.
06Padlockable Handle
Integrated hasp accepts standard padlocks (not included) for lockout/tagout (LOTO) compliance during maintenance.
07Weatherproof Outdoor Models (NEMA 3R)
Gasketed doors and sloped tops prevent water ingress. Suitable for rain, snow, dust, and hose-directed water.
08Straight-Through Wiring Design
Line and load terminals are aligned for clean, direct cable runs - reduces clutter and improves heat dissipation.
09Clear ON/OFF Indication
Large red/green labels and visible handle position ensure operators know the status at a glance.
Key Applications
Main service entrance disconnects
HVAC system isolation (indoor/outdoor)
Well pump and pool motor protection
Solar PV array shutdown switches
Generator transfer switch bypass
Workshop and garage sub-panels
Agricultural and irrigation systems
Light industrial machine disconnects

FAQ
Q: Can I use this as my main service disconnect?
A: Yes - if installed per local electrical code and sized correctly for your service amperage.
Q: What's the difference between fusible and non-fusible?
A: Fusible: Contains fuses inside for overcurrent protection.
Non-fusible: Just a switch - requires upstream breaker or fuse for protection. Ideal for solar or generator isolation.
Q: Are these suitable for DC applications?
A: Only specific models support DC voltage (up to 250V). Check specs carefully - DC arcs harder to interrupt than AC.
Q: Do I need special tools to install?
A: No - standard screwdrivers and wrenches work fine. Knockouts can be removed with a hammer and punch.
Q: Can I mount this on a pole?
A: Yes - outdoor models include mounting ears for pole or bracket installation.
Q: Where do I buy replacement fuses?
A: PAK30, PAK60, and PAK100 fuses are sold separately. Available through our website or major electrical suppliers.
Q: Is there a 100A model?
A: Some indoor fusible models support up to 100A - check product table or contact us for custom orders.
