Key Features
- 4-position barrier strip terminal block with screw-clamp wire termination for secure, vibration-resistant connections in industrial environments
- Standard pitch layout enabling easy PCB integration and tooling compatibility with common connector footprints in power distribution boards
- Würth Elektronik WR-TBL series construction offering high current and voltage ratings suitable for 300 V AC power wiring applications
Applications
The 691414720004B is used in industrial control panels, power distribution boards, and machine safety relay circuits where reliable multi-wire field termination is required. Its 4-position barrier strip layout allows up to 4 independent conductors to be terminated on a single PCB-mounted block, simplifying field wiring in enclosures. HVAC controllers, motor drive interface boards, and PLC expansion modules rely on this terminal block type for robust screw-down connections rated for repetitive maintenance and rewiring cycles.

Frequently Asked Questions
How many wire positions does the 691414720004B provide, and what wire gauge range does it accept?
The 691414720004B has 4 wire positions, each accepting conductor sizes typically in the range of 28 AWG to 12 AWG (0.08 mm² to 4 mm²) depending on the specific WR-TBL series pitch. This covers both thin signal wires and thicker power conductors up to 4 mm², making the block versatile for mixed signal-and-power wiring in industrial panels.
What voltage and current ratings make the 691414720004B suitable for industrial power distribution wiring?
Würth Elektronik WR-TBL barrier strip terminal blocks in this series are typically rated for 300 V AC and up to 15 A per position, sufficient for low-voltage power distribution circuits and 24 V DC control bus wiring. These ratings comply with relevant IEC 60947-7-1 and UL 508 industrial terminal block standards for panel-mount applications.
How does a barrier strip terminal block like the 691414720004B differ from a pluggable connector for field wiring?
A barrier strip uses permanent screw-clamp termination directly on the PCB, offering lower contact resistance and higher vibration resistance compared to pluggable push-in or spring-cage alternatives. Pluggable connectors allow the field wiring harness to be disconnected without tools in under 5 seconds, while a barrier strip requires a flathead screwdriver but provides a more mechanically stable connection for fixed installations subject to thermal cycling between -40 °C and +105 °C.
For a 4-channel motor relay board, why would an engineer choose a 4-position terminal block over individual ring-lug terminals?
A 4-position barrier strip consolidates all 4 output connections into a single PCB-mounted component, reducing assembly time from 4 separate lug-bolting operations to one screw-tightening sequence per conductor. The block also provides a minimum 5 mm creepage distance between adjacent positions, meeting IEC 60664-1 clearance requirements for 300 V AC circuits without adding insulating barriers between individual ring-lug studs.
