Hubbell Wiring Device-kellems HBLFRBL Female Connector 400A

Product Description

The HUBBELL WIRING DEVICE-KELLEMS HBLFRBL is a single-pole female connector designed for heavy-duty power distribution applications. It uses a threaded stud termination method and is rated for 400 amps at up to 600 VAC or 250 VDC. Built to handle conductors up to 4 AWG, this connector is suited for high-current single-pole wiring systems found in industrial facilities, construction sites, and commercial power distribution setups. Electricians and industrial maintenance technicians install this type of connector where reliable, high-amperage single-pole connections are required.

This connector is intended for use in demanding environments where exposure to moisture, dust, or corrosion is a concern. The NEMA 3R, 4X, and 12 ratings make it appropriate for outdoor, washdown, and industrial indoor applications. It is commonly used in stage power, temporary power distribution, and industrial machinery wiring where single-pole cam-style or stud-style connectors are the specified connection method.

Key Features

• 400-amp rating supports heavy-duty power distribution loads
• Dual voltage rating: 600 VAC and 250 VDC
• Threaded stud termination for secure, low-resistance conductor attachment
• Accepts conductors up to 4 AWG maximum
• NEMA 3R, 4X, and 12 rated for outdoor, corrosion-resistant, and industrial indoor environments
• UL Listed and cUL Listed for compliance with North American safety standards

Compatibility

Designed as an OEM-style single-pole female connector for high-current power distribution systems requiring threaded stud termination and NEMA 4X-rated housings.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for high-amperage connectors and single-pole devices. De-energize and lock out the circuit before making or breaking any connections. Ensure the conductor is properly sized and terminated to the threaded stud with the appropriate hardware to maintain a secure, low-resistance joint. Inspect the connector housing for damage before each use, particularly in environments where NEMA 4X protection is relied upon.
