256-401 Description

Short technical summary and product information.

The Wago 256-401 is a 1-pole stackable PCB terminal block from the 256 Series. It features a push-button actuated CAGE CLAMP connection, providing a maintenance-free and tool-less wire termination method for solid and fine-stranded conductors from 0.08 to 2.5 mm² (12-28 AWG).

 

Electrical ratings include 24 A rated current and 250 V rated voltage per IEC/EN 60664-1 (Overvoltage category III, Pollution degree 3), with alternative ratings up to 630 V depending on environmental conditions. UL 1059 ratings are 15 A (Group B) and 10 A (Group D) at 300 V. The impulse withstand voltage is 4 kV.

 

Mechanical specifications include through-hole (THT) mounting with solder pins, a 45° conductor entry to board orientation, and a compact outline of 7.8 mm width, 22.2 mm height, and 17.6 mm depth. The pin spacing is 5/5.08 mm, and the strip length should be 5 to 6 mm. The gray housing has tin-plated contacts, and the block is designed for wire-to-board applications with a commoning option for potential distribution.
