Product details

The G7J-4A-B AC200/240 is a 4PST-NO power relay from Omron's G7J Series, rated to switch 25 A at 240 V AC — enough for motor loads up to 3 hp at 240 V AC or 1-1/2 hp at 120 V AC. The 200/240 V AC coil draws 9 mA at 200 V and 10.8 mA at 240 V, so it lands in standard 200–240 V line-voltage control circuits without a separate transformer.

Bracket-mounted with 10 screw terminals — no DIN-rail clip, so plan for panel drilling or a separate mounting plate. The push-to-test button on the relay body simplifies commissioning checks without needing to energize the coil. Dielectric strength is 4000 V AC between coil and contacts, which gives solid isolation for line-voltage switching in control panels.

Frequently asked questions

What are the key contact ratings for this relay?

The main contact rating is 25 A at 240 V AC. For DC loads, it is rated 25 A at 30 V and 100 mA at 24 V. Motor ratings are 3 hp at 240 V AC and 1-1/2 hp at 120 V AC.

What coil voltage does this relay use?

The coil is rated for 200/240 V AC, drawing 9 mA at 200 V and 10.8 mA at 240 V. Nominal at 60 Hz is 240 V AC.
