Power Relays
G7L General Purpose Relay
A High-capacity, High-dielectricstrength Relay Compatible with Momentary Voltage Drops
- No contact chattering for momentary vol]tage drops up to 50% of rated voltage.
- Wide-range AC-activated coil that handles 100 to 120 or 200 to 240 VAC at either 50 or 60 Hz.
- Miniature hinge for maximum switching power, particularly for inductive loads.
- Flame-resistance materials (UL94V-0- qualifying) used for all insulation material.
- Quick-connect, screw, and PCB terminals, and DIN track mounting available.
