257-448 Description

Short technical summary and product information.

The Wago 257-448 is a 48-position PCB terminal block from the 257 Series, featuring the CAGE CLAMP® connection technology. It is designed for quick and easy conductor termination without the need for ferrules or special tools, using a push-button actuation mechanism. This terminal block accepts solid and fine-stranded conductors from 0.08 to 2.5 mm² (12-28 AWG) with a strip length of 5 to 6 mm.

 

Electrical ratings include a rated current of 24 A per IEC/EN 60664-1 and 15 A per UL 1059 and CSA. Voltage ratings vary by standard and pollution degree, with up to 630 V for IEC category II/pollution degree 2 and 300 V for UL/CSA. The rated impulse withstand voltage is 4 kV.

 

The terminal block has a pin spacing of 5/5.08 mm, is through-hole mounted, and mates horizontally with the board. It offers a commoning option for linking multiple potentials. Dimensions are 242.9 mm length, 24.4 mm width, and 14.2 mm height. The housing is gray, and contacts are tin-plated.

 

This component is suitable for a wide range of industrial and commercial PCB interconnection applications, including as a pluggable connector, panel feedthrough header, or connector for rail-mount terminal blocks.
