Power Relay G7L
- The delivery date is unstable due to the difficulty in obtaining materials, components, etc. There is no prospect of the next arrival of products for which orders have been suspended.
A power relay with a high capacity and high dielectric strength that can handle momentary voltage drops.
[Features]
· No contact chattering for momentary voltage drops up to 50% of the rated voltage.
· A wide range coil that covers 100 V AC type from 100 to 120 V AC 50/60 Hz or 200 V AC type from 200 to 240 V AC 50/60 Hz with a single coil.
· High capacity that is particularly able to manage inductive loads with powerful force.
· All insulating materials are flame retardant and comply with UL94 V-0 standards.
· Comes in a wide variety of types including tab terminals, screw terminals, PCB terminals, etc. Surface connection sockets are also available.
· Standard products compliant with UL, CSA, and TÜV and meet the IEC950 standards.
· Safe design with 3 mm contact gap.
[Applications]
· Widely applicable to factory automation as well as non-factory automation equipment.

Note 1. Industrial Relays, 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 AC rated current is the same value for both 50 and60 Hz.)
Note 2. The coil inductance shown is a reference value.
*The figures for the operating characteristics are for a coil temperature of +23°C.
Note 4. The maximum allowable coil voltage refers to the maximum value in a varying range of operating power voltage, measured at ambient temperature 23°C.
Note 5. The "to" (for example "100 to 120") represents the range of rated voltages.
