Cooper Bussmann HRH Inline Fuse Holder 9 Amp 32 Vac

Product Description

The COOPER BUSSMANN HRH is an inline fuse holder rated for 32 volts AC and up to 9 amps, designed to protect low-voltage wiring circuits from overcurrent conditions. It accepts fuses measuring 0.69 inches wide and 0.25 inches in diameter, making it compatible with standard 1/4-inch diameter cartridge fuses. The holder uses wire lead termination, allowing it to be spliced directly into a circuit without the need for a panel-mounted or block-style holder. Licensed electricians and HVAC technicians install this type of holder in control circuits, accessory wiring, and low-voltage applications where in-line fuse protection is required.

This inline fuse holder is suited for residential and light commercial electrical and HVAC control wiring applications. It is commonly installed in branch circuits, low-voltage control lines, and accessory power runs where a dedicated fuse block or panel mount is not practical. The wire lead design allows integration into existing wire runs with standard splice connectors or solder connections, making it a straightforward field installation for electricians and HVAC service technicians working on control circuits and equipment accessory wiring.

Key Features

• Wire lead termination for direct in-line splice installation
• Compact, lightweight design at 0.06 pounds for easy routing in tight spaces
• Single-unit packaging suitable for individual circuit or repair applications

Compatibility

Compatible with cartridge fuses measuring 0.69 inches in width and 0.25 inches in diameter. Designed as a general-purpose inline fuse holder for low-voltage wiring circuits up to 32 volts AC.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC technician in accordance with applicable NEC requirements for overcurrent protection and circuit wiring. De-energize and lock out the circuit before splicing the fuse holder into the wire run. Ensure wire gauge and connection method are appropriate for the rated amperage. Do not exceed the 9-amp or 32-volt AC ratings of the holder.
