Omron G7L-2A-TUBJCBAC120 Relay

The Omron G7L-2A-TUBJCBAC120 is a high capacity power relay engineered for heavy-duty HVACR and industrial control applications. Built with a DPST-NO (Double Pole Single Throw-Normally Open) contact configuration, this unit is rated for a 25 Amp switching capacity, making it a reliable choice for managing high-inrush loads such as fluid pumps, compressors, and resistive heating elements. The integrated test button allows for immediate manual circuit verification, while the upper bracket mounting design simplifies panel installation for field technicians.

Operating on a 100-120Vac coil, this Omron power relay features specialized construction to withstand momentary voltage drops up to 50% of the rated voltage without contact chattering. The quick-connect terminals (#250) facilitate fast wiring in tight enclosures. Utilizing UL Class B insulation and flame-resistant materials, this relay is built for longevity in demanding environments where temperature stability and dielectric strength are paramount. Whether you are servicing a commercial air conditioner or a water processing controller, the G7L series provides the robust electrical isolation and switching power required for professional-grade power management.

Key Benefits for Technicians:

• High Switching Capacity: Handles up to 25A at 277VAC, ideal for inductive motor loads and large HVAC compressors.
• Manual Override: Features a test button for rapid diagnostic checks without needing to energize the control circuit.
• Voltage Stability: Designed to maintain contact closure during significant 120V coil voltage dips, preventing equipment cycling.
• Simplified Installation: Upper bracket mounting and quick-connect terminals reduce labor time during field replacements.
• Industrial Durability: Incorporates DPST-NO contacts with high dielectric strength and UL94V-0 rated insulation.

Common Technical Questions:

Can this relay replace a standard contactor in HVAC units?
Yes, provided the load does not exceed the 25 Amp resistive or inductive rating. It is a common upgrade for motor drivers and heater switching controllers where space is limited but high-power handling is necessary.

How do I test the internal contacts without power?
The built-in manual test button allows you to mechanically actuate the contacts to check for continuity across the DPST-NO terminals using a multimeter.

Is the upper bracket removable for alternate mounting?
The "UB" suffix indicates a permanent upper bracket mounting configuration. For E-bracket or DIN rail mounting, a different sub-model or adapter would be required.
