Overview

The 691137710003 is a 3-position, horizontal-entry terminal block from Wurth Elektronik's WR-TBL Series 1377. Designed for through-hole mounting on a 5.00mm pitch, it features a screw-based leaf spring wire guard mechanism to ensure reliable electrical contact. This connector is rated for 16A at 300V, making it suitable for a wide range of power and signal distribution tasks on printed circuit boards.

Why Choose This Part

The leaf spring wire guard prevents the screw from directly damaging fine-stranded wires, ensuring better long-term reliability. Its UL94 V-0 flammability rating and 110 degrees C maximum operating temperature make it robust for demanding environments. Additionally, it supports a wide wire gauge range from 12 to 30 AWG, providing significant flexibility for different cable types.
