Hubbell Wiring Device-kellems HBL1203L Key Lock Switch 15A

Product Description

The HUBBELL WIRING DEVICE-KELLEMS HBL1203L is a 3-pole, industrial-grade key lock three-way switch rated for 15 amps and 120 to 277 VAC. Designed for demanding commercial and industrial environments, this switch uses a key-operated locking mechanism to prevent unauthorized operation or accidental switching. Single-phase wiring is supported across the full voltage range. The operating temperature range spans -40 to 239 degrees F, making it suitable for installations in extreme ambient conditions. Licensed electricians working in industrial facilities, manufacturing plants, or heavy commercial buildings are the primary installers of this device.

This switch is intended for industrial-grade electrical installations where controlled access to switching functions is required. The key lock mechanism adds a layer of access control that standard toggle or rocker switches do not provide. Typical applications include machinery disconnect control, lighting circuits requiring restricted operation, and process equipment switching in facilities that follow strict lockout and access protocols. The wide voltage range of 120 to 277 VAC accommodates single-phase circuits across both standard and high-leg distribution systems.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize the circuit and verify voltage absence with a meter before beginning any wiring work. Confirm that the panel and branch circuit are rated to handle the 15-amp load before connecting. Follow all applicable local codes for industrial wiring enclosures and device mounting.
