General Purpose Relay
G7L
• Ideally suited for high-inrush fluid pump controls: pool/spa, water
processing, emergency, chemical industry, etc.
• High-capacity, high-withstand voltage relay with no contact chatter-
ing for momentary voltage drops up to 50% of rated voltage.
• UL Class B construction standard.
• Wide-range AC-activated coil that handles 100 to 120 VAC at either
50 or 60 Hz.
• Miniature hinge for maximum switching capacity, particularly for in-
ductive loads.
• Flame resistant materials (UL94V-0-qualifying) used for
all insulation material.
• Quick-connect, screw, and PCB terminals available.
• Standard models are UL, CSA, and TUV approved;
VDE/IEC 950 versions are now available. Meet pollution degree 3,
Material Group II & III.
Ordering Information
To Order: Select the part number and add the desired coil voltage rating (e.g., G7L-1A-T-CB-AC100/120).
