Aci 117839 Fused Safety Switch 10 Amp 3 Pole

Product Description

The ACI 117839 is a fused, 3-pole safety switch rated at 10 amps, designed for use in control circuits requiring reliable overcurrent protection and manual disconnect capability. The non-metallic enclosure keeps the assembly lightweight and corrosion-resistant, making it a practical choice for environments where metal housings are not preferred. At 0.6 pounds and a compact footprint of 4.29 inches tall, 1.57 inches wide, and 1.5 inches deep, the switch fits into tight panel or enclosure spaces. It carries CE and cULus certifications, confirming it meets recognized safety and performance standards. Licensed electricians and HVAC controls technicians are the primary installers for this type of device.

This safety switch is suited for residential and light commercial control panel applications where a fused disconnect is required in a low-current circuit. The normally open and dual normally closed (NO, 2NC) contact configuration supports interlock and safety circuit designs common in HVAC, building automation, and similar control systems. Its non-metallic body is appropriate for installations where electrical isolation from the mounting surface is needed or where moisture or corrosion is a factor in the operating environment.

Key Features

• Fused design provides overcurrent protection within the switch body
• 3-pole configuration with NO and 2NC contact arrangement for interlock and safety circuit use
• Non-metallic enclosure resists corrosion and provides electrical isolation
• Compact dimensions fit tight panel and enclosure spaces
• CE and cULus certified, with UL File E131787

Compatibility

Designed as an OEM-style replacement or new-installation safety switch for low-current fused control circuit applications in HVAC, building automation, and related control panel assemblies.

Installation Notes

Installation should be performed by a licensed electrician or qualified controls technician in accordance with the NEC and applicable local codes. De-energize and lock out the circuit before handling or wiring the switch. Verify that the replacement fuse rating matches the circuit design before restoring power. Do not exceed the rated 10-amp load on any pole.
