Aci 111674 Safety Switch 10 Amp Fused 2 Pole

Product Description

The ACI 111674 is a fused, 2-pole safety switch rated at 10 amps, designed for use in HVAC, electrical, and mechanical systems where a reliable disconnect point is required. The non-metallic housing keeps the unit lightweight at 0.3 pounds and suited for installations where corrosion resistance or non-conductive enclosures are necessary. The normally open (NO) contact configuration provides a clear circuit-interrupt state when the switch is actuated. This switch is installed by licensed electricians and HVAC technicians working on low-voltage and line-voltage control circuits.

This safety switch is typically used in residential and light commercial applications as a service disconnect or interlock device. It fits into control panels, air handler cabinets, and similar enclosures where a manual or safety-actuated disconnect is required. Its compact footprint — 3.41 inches tall, 1.97 inches wide, and 1.24 inches deep — makes it practical in tight panel spaces. The fused design provides built-in overcurrent protection at the switch location.

Key Features

• 10-amp fused design provides overcurrent protection at the disconnect point
• 2-pole configuration interrupts both circuit legs simultaneously
• Normally open (NO) contact configuration for standard safety interlock wiring
• Non-metallic housing resists corrosion and reduces weight
• Compact dimensions fit standard control panel and air handler enclosures
• Listed to cULus and CE standards under UL File E131787

Compatibility

Designed as an OEM-style replacement safety switch for residential and light commercial HVAC and electrical control applications requiring a fused 2-pole disconnect.

Installation Notes

Installation should be performed by a licensed electrician or HVAC technician in accordance with the National Electrical Code (NEC). Disconnect and lock out all power to the circuit before handling or wiring the switch. Verify the circuit amperage does not exceed the 10-amp rating before installation. Confirm contact configuration and pole count match the existing wiring diagram before replacing an existing switch.
