745-821 Description

Short technical summary and product information.

The Wago 745-821 is a 1-pole stackable PCB terminal block designed for wire-to-board connections. It is rated for 20A and 300V, accommodating wire gauges from 12 to 28 AWG with a maximum wire cross section of 4 mm².

 

This terminal block uses a screwless spring cage (CAGE CLAMP®) tension clamp termination for fast and reliable wire connection. It mounts via through hole with a pin spacing of 10 mm and mates at a 45° (135°) angle to the board. The housing is gray.

 

The 1-pole design allows stacking multiple units to create multi-pole configurations as needed. It is suitable for industrial control, building automation, and general electrical interconnection applications.
