The TB-SP04-10 includes ten 4-position spring clamp terminal blocks with 3.5mm centerline spacing. The removable terminal blocks are keyed to prevent being inserted upside down.

The lever-style clamping mechanism requires no tools making field installation easy. The clamping mechanism also provides superior wire holding properties and automatically adjusts the spring tension on wire diameters from 16-28 AWG. The terminal block’s very tight friction design prevents accidental separation due to vibration.

Spring clamp and screw terminal blocks with 5-position or 6-position terminals are also available in packs of ten.
