WAGO 773-494 PUSH WIRE Splicing Connector 4-Conductor 2.5mm² Pack of 100

The WAGO 773-494 is a 4-conductor PUSH WIRE splicing connector from the 773 Series, designed for connecting solid and stranded copper conductors in surface-mounted and flush-mounted junction boxes for building installations and Ex (hazardous area) applications. The connector accepts conductor cross-sections from 0.75 mm² to 2.5 mm² and carries a rated current of 24 A at 550 V under EN 60079 Ex e II conditions. Side-entry PUSH WIRE push-in actuation requires no actuation tool; a strip length of 12 mm is required for all conductor types.

Sold as a pack of 100 pieces.
