HUBBELL KELLEMS

Tentang HUBBELL KELLEMS

Hubbell Kellems is a brand within the Hubbell Incorporated portfolio, a publicly traded electrical equipment manufacturer headquartered in the United States. The Kellems line is historically associated with wire management and cable grips, but the product range supplied by 3G Electric focuses specifically on manual motor switches. These switches are designed for local on/off control of motors and other loads in industrial and commercial installations. The catalog includes both open (un-enclosed) and enclosed models, with enclosures carrying NEMA ratings such as 1 and 3R for indoor and outdoor use respectively. All switches are rated for a maximum voltage of 600V AC and are available in 2-pole and 3-pole configurations with current ratings from 30 A to 85 A. Mounting style is surface-mount, and pilot lights are not included on the listed models. The open switches (e.g., HBL7853D, HBL7810D) are intended for installation inside control panels or junction boxes where the environment is clean and dry. The enclosed switches (e.g., HBL1389, HBL13R22) come in non-metallic enclosures that provide protection against dust, moisture, and incidental contact, making them suitable for standalone mounting in more demanding conditions. 3G Electric stocks these Hubbell Kellems manual motor switches as part of its broader industrial equipment offering. The company supports global procurement by maintaining inventory in Singapore and coordinating international logistics. For plant engineers and maintenance managers, these switches offer a straightforward means of disconnecting motor circuits for maintenance or emergency stops, with ratings that align with common motor sizes in the 10–50 hp range at 480V. The absence of integrated overload protection means these switches are typically used in conjunction with separate motor starters or circuit breakers. The NEMA 3R enclosed models are particularly relevant for outdoor applications such as HVAC units, pumps, or conveyors exposed to rain or hose-down. All units are surface-mountable, simplifying retrofit or new installation. The product line covers a practical range of amperages, allowing selection based on full-load current of the connected motor. 3G Electric provides these switches with full traceability via manufacturer part numbers, enabling engineers to specify replacements or new builds with confidence in dimensional and electrical compatibility.
