256-743 Description

Short technical summary and product information.

The Wago 256-743 is a 1-pole stackable PCB terminal block from the 256 series, featuring push-button actuation and CAGE CLAMP connection technology. It is designed for tool-less wire termination and offers a commoning option for potential distribution.

 

Electrical ratings include 15 A (UL/CSA) and 24 A (IEC/EN) current, with voltage ratings of 300 V (UL/CSA) and up to 630 V (IEC/EN depending on overvoltage category). It accepts solid and fine-stranded conductors from 0.08 to 2.5 mm² (12-28 AWG) with a strip length of 5-6 mm.

 

The terminal block mounts via through-hole (THT) with a solder pin length of 5.5 mm. It features a dual pin spacing of 5/5.08 mm and a 45° conductor entry angle for space-saving PCB layouts. Dimensions are 7.8 mm width, 22.2 mm height, and 17.6 mm depth. The housing is light gray.

 

This component is suitable for industrial control, building automation, and PCB power distribution applications where reliable, vibration-resistant connections are required.
