Power Relay A High-capacity, High-dielectric-strength, Multi-pole Relay Used Like a Contactor • Miniature hinge for maximum switching power for motor loads as well as resistive and inductive loads. • No contact chattering for momentary voltage drops up to 50% of rated voltage. • Withstanding more than 4 kV between contacts that are different in polarity and between the coil and contacts. • Flame-resistant materials (UL94V-0-qualifying) used for all insulation material. • Standard models approved by UL and CSA. For the most recent information on models that have been certified for safety standards, refer to your OMRON website. Refer to Safety Precautions for All Relays. Model Number Structure ■ Model Number Legend G7J - 2. Terminal Shape P: PCB terminals B: Screw terminals T: Quick-connect terminals (#250 terminal) 3. Contact Structure Z: Bifurcated contact None: Single contact Note: For bifurcated contact type, output is 1NO (4PST-NO) or 1NC (3PST-NO/SPST-NC). Ordering Information ■ List of Models Mounting type Contact form Screw terminals Quick-connect terminals Note: These Relays need a W-bracket (sold separately) for mounting. When ordering specify the voltage. Example: G7J-4A-P 240 VAC Rated coil voltage

Specifications ■ Coil Ratings Rated voltage AC Rated current Coil resistance 75% max. of rated 15% min. of rated 110% of rated voltage voltage voltage Power consumption Must-release voltage Must-operate voltage Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%/–20% for AC rated current and ±15% for DC coil resistance. (The values given for AC rated current apply at 50 Hz or 60 Hz.) 2. Performance characteristic data are measured at a coil temperature of 23°C. 3. The maximum voltage is one that is applicable to the Relay coil at 23°C....

G7J Note: 1. The above values are all initial values. 2. The contact resistance was measured with 1 A at 5 VDC using the voltage drop method. 3. The operate and the release times were measured with the rated voltage imposed with any contact bounce ignored at an ambient temperature of 23°C. 4. The insulation resistance was measured with a 500-VDC megger applied to the same places as those used for checking the dielectric strength. 5. The electrical endurance was measured at an ambient temperature of 23°C. 6. This value was measured at a switching frequency of 60 operations per minute. ■ Approved...

Safety Precautions Refer to Safety Precautions for All Relays. Faston Tabs PCB Terminal-equipped Relays weigh approximately 140 g. Be sure that the PCB is strong enough to support them. We recommend dual-side through-hole PCBs to reduce solder cracking from heat stress. Do not impose excessive external force on the G7J in the horizontal or vertical directions when inserting the G7J to the Faston receptacle or pulling the G7J out from the Faston receptacle. Do not attempt to insert or pull out more than one G7J Unit together. Mount the G7J with its test button facing downwards. The Relay may malfunction...
