COLUMBUS ELECTRIC

Columbus Electric is a manufacturer of thermostats and pressure switches, with a product line that includes line-voltage analog thermostats, gas wall and ceiling heater thermostats, adjustable set-point air pressure switches, nonprogrammable thermostats for portable cooling equipment, attic fan thermostats, and hazardous-location single-stage controls. The brand is known for producing controls that serve a range of industrial and commercial applications, particularly where environmental conditions require robust, repeatable switching. Products are available in various housing materials—plastic, steel, and aluminum—and support voltage ranges from 24V AC to 277V AC, as well as millivolt (750MV) systems. Temperature control ranges span from 40°F to 130°F, depending on the model, with adjustable differentials on certain units. Pressure switches cover sensing ranges from 0.05 in wc to 12 in wc, with auto-reset functionality and SPDT or SPST switching actions. Hazardous-location models feature aluminum enclosures and are rated for use in environments requiring explosion-proof or intrinsically safe controls, with adjustable temperature ranges from 40°F to 110°F and DPDT or SPDT switching. 3G Electric supplies Columbus Electric products globally, supporting plant engineers, maintenance managers, and procurement specialists who need reliable temperature and pressure control components for burner systems, HVAC, gas appliances, and process equipment. The product range is suited for both OEM and replacement applications, with specifications that allow direct substitution in existing systems. 3G Electric provides logistics support to ensure availability of these controls across various regions, without geographic restrictions.

Frequently asked questions

Common questions about COLUMBUS ELECTRIC from 3G Electric.

What voltage ranges do Columbus Electric thermostats support?

Columbus Electric thermostats are available in multiple voltage configurations. Line-voltage analog models support 24 to 277V AC, while gas wall and ceiling heater thermostats operate at 750MV or 24V. Hazardous-location models are rated for 120/277V AC or 24 to 277V AC, depending on the part number. Always verify the specific model's nameplate voltage before installation.

Are Columbus Electric pressure switches suitable for low-pressure sensing?

Yes, Columbus Electric adjustable set-point air pressure switches, such as the GRH3AD, sense pressures from 0.05 in wc to 12 in wc. These switches feature auto-reset and SPDT switching, making them appropriate for low-pressure air or gas applications in HVAC and industrial burner systems.

What enclosure materials are used in Columbus Electric hazardous-location thermostats?

Columbus Electric hazardous-location thermostats, like the HLT-1 and HLT-2-G, use aluminum enclosures. Aluminum provides corrosion resistance and durability in environments where explosive gases or combustible dusts may be present. These models are designed for single-stage control with adjustable differentials.

Can Columbus Electric thermostats be used for both heating and cooling applications?

Yes, certain models are designed for dual-function use. For example, the ETD9STGS line-voltage mechanical thermostat supports heat or cool operation with SPDT switching and an exposed dial. Other models, such as the attic fan thermostat 1A22-7, are cool-only. Check the application specification for each part number.

What is the temperature control range for Columbus Electric gas wall and ceiling heater thermostats?

The P322016 gas wall and ceiling heater thermostat has a control range of 50° to 90°F. It operates at 750MV or 24V and is designed for use with gas-fired heating equipment. This range is typical for residential and light-commercial space heating applications.

Do Columbus Electric thermostats include adjustable differentials?

Some models feature adjustable differentials. For instance, hazardous-location thermostats HLT-1 and HLT-2-G have adjustable differentials, allowing fine-tuning of the switching hysteresis. Line-voltage analog models may have fixed differentials; refer to the product specifications for each SKU.
