Key Features – Built for Electricians, Trusted by Installers
01Dual Environment Compatibility
The painted steel cabinet is engineered for dry indoor environments such as utility rooms, electrical closets, and basement mechanical areas. While the core contact assembly shares design heritage with outdoor-rated variants, this NEMA 1 unit is optimised for climate-controlled interiors where dust and incidental contact are the primary concerns.
02High-Capacity Power Handling
Rated for 100 A at 120/240 V, the switch accommodates large residential or commercial loads. The heavy-duty contact assembly and robust blade design ensure reliable make-break performance under full-load conditions.
03User-Centric Design
A bright orange polymer handle cover provides high-visibility contrast against the grey steel enclosure. The ergonomic grip and positive detent allow confident operation even in dimly lit electrical rooms.
04Non-Fusible Configuration
Without internal fuse holders, the switch functions as a pure disconnect device. This simplifies inventory-no spare fuses required-and reduces long-term maintenance to contact inspection and torque checks.
05Compact and Space-Efficient
Measuring 333 mm H × 240 mm W × 137 mm D, the enclosure fits standard electrical closets and tight utility alcoves. Multiple conduit knockouts on the top, bottom, and rear allow flexible cable routing without field drilling.
Key Applications
- Residential Backup Power: Isolates standby generators from the utility grid in homes, keeping refrigeration, HVAC, and emergency lighting circuits online during grid failures.
- Commercial Continuity: Disconnects utility feeds for small offices and retail stores with generator backup, protecting POS terminals, security cameras, and network hardware.
- Municipal Buildings: Acts as the service disconnect for community centres and library electrical rooms, permitting safe access to panelboards during public events.

FAQ
Q1: Is the orange handle cover replaceable if damaged?
A:Yes, the polymer handle cover is a replaceable component. Contact the supplier with the product number GAK-100 to order a spare cover. Do not operate the switch with a missing or cracked cover.
Q2: Can I mount this switch directly on a drywall surface without a plywood backboard?
A: It is recommended to mount on a plywood or steel backboard for structural integrity, especially with 1 AWG conductors that exert mechanical stress. If mounting on drywall alone, use toggle bolts or anchors rated for at least 50 kg pull-out force.
Q3: Does the switch include a neutral bar for grounding the enclosure?
A: Yes, a dedicated ground lug is pre-installed inside the enclosure. Connect the equipment grounding conductor here to bond the steel chassis. A separate neutral bar is not included; terminate neutrals in the adjacent panelboard.
Q4: How much side clearance is required for the handle to swing fully?
A: Allow at least 150 mm of unobstructed space to the right of the handle (when facing the switch) for full 90-degree swing. This ensures the handle can snap positively to the ON and OFF positions without hitting adjacent conduit or walls.
Q5: Can this non-fusible switch be used upstream of a fused disconnect?
A: Yes. This switch provides the visible isolation point, while the downstream fused disconnect handles overcurrent protection. Coordinate the ampere ratings so the fuse device does not exceed 100 A.
