HUBBELL KELLEMS
Frequently asked questions
Common questions about HUBBELL KELLEMS from 3G Electric.
What are the current and voltage ratings available for Hubbell Kellems manual motor switches?
Hubbell Kellems manual motor switches are available with current ratings of 30 A, 40 A, 50 A, 60 A, and 85 A. All models have a maximum voltage rating of 600V AC. The switches come in 2-pole and 3-pole configurations. For example, the HBL7810D is a 30 A, 3-pole switch, while the HBL7832 is a 30 A, 2-pole switch. The 85 A model, HBL7883D, is a 3-pole switch. These ratings allow selection based on the motor's full-load current and the system voltage. The switches are designed for surface mounting and do not include an enclosure or pilot light.
Are Hubbell Kellems manual motor switches supplied with an enclosure?
No, the Hubbell Kellems manual motor switches listed by 3G Electric are open-style devices. They do not include an enclosure or a pilot light. They are intended to be mounted within a control panel or a separate enclosure that provides the necessary environmental protection and operator safety. The open construction allows for direct wiring and integration into existing electrical assemblies. If an enclosed switch is required, a suitable enclosure must be sourced separately. The switches have a surface mounting style, meaning they can be mounted directly to a flat surface inside an enclosure.
What is the difference between 2-pole and 3-pole Hubbell Kellems manual motor switches?
The number of poles refers to the number of separate circuits the switch can control. A 2-pole switch is typically used for single-phase motors or for switching two lines of a three-phase system. A 3-pole switch is used for three-phase motors, allowing simultaneous switching of all three phases. Hubbell Kellems offers both configurations. For instance, the HBL7842D is a 2-pole, 40 A switch, while the HBL7843D is a 3-pole, 40 A switch. The choice depends on the motor type and the electrical system. Both types have a maximum voltage rating of 600V AC and are surface-mount, open-style devices.
Can Hubbell Kellems manual motor switches be used for local motor control?
Yes, Hubbell Kellems manual motor switches are designed for local on/off control of motors and equipment. They provide a manual means to disconnect power or start/stop a motor at the point of use. This is useful for maintenance, emergency stops, or where a centralized control system is not practical. The switches are rated for 600V AC and are available in various current ratings to match motor loads. They are open-style, so they must be installed inside an appropriate enclosure. Typical applications include conveyors, pumps, and machine tools. They are not intended for frequent switching duty beyond their rated capacity.
What is the maximum voltage rating for Hubbell Kellems manual motor switches?
All Hubbell Kellems manual motor switches in the 3G Electric catalog have a maximum voltage rating of 600V AC. This rating applies across the range, from the 30 A models to the 85 A models. The 600V AC rating is suitable for many industrial motor control applications, including those operating at 480V AC or lower. It is important to verify that the switch's voltage rating meets or exceeds the system voltage. The switches are not rated for DC applications unless specifically stated. Always follow local electrical codes and manufacturer instructions for installation.
