PCB terminal block, 740 Series, gray Our PCB terminal block (item number 740-104) is designed for seamless electrical installations. It is a universal connector that can be used practically anywhere, for example, as a pluggable PCB connector, panel feedthrough header, connector for rail-mount terminal blocks, or a floating connector for different mounting methods. Strip lengths must be between 6 and 7 mm when connecting conductors to this PCB terminal block. This product features one conductor terminal and utilizes CAGE CLAMP®. Our renowned universal connection known as CAGE CLAMP® leads the way when it comes to connection technology and electrical inter­ Page 1/5 Version 12.05.2026 Continued on next page # **Data Sheet | Item Number: 740-104 https://www.wago.com/740-104** connections. Dimensions: (20 x 23.3 x 11.1) mm (width x height x depth). Depending on the conductor type, this PCB terminal block is designed for conductor cross sections ranging from 0.08 mm² to 2.5 mm². Tin is used for coating the contact surfaces. This PCB terminal block is operated with an operating tool. THT is used to assemble the PCB terminal block. Insert the conductor into the board at a 0° angle.. |**Notes**||||||||||| |---|---|---|---|---|---|---|---|---|---|---| |Variants:||||||Other pole numbers||||| |||||||Other colors||||| |||||||Mixed-color PCB connector strips||||| |||||||Direct marking||||| |||||||Other versions (or variants) can be requested from WAGO Sales|||or configured at https://con­|| |||||||figurator.wago.com/.||||| |.||||||||||| |**Electrical data**||||||||||| |**Ratings per**|||**IEC/EN 60664-1**|||**Approvals per**|||**UL 1059**|| |Overvoltage category||III|III|II||Use group||B|C|D| |Pollution degree||3|2|2||Rated voltage||300 V|-|300 V| |Nominal voltage||300 V|320 V|630 V||Rated current
