The spring-clamp terminals on these blocks make wire installation faster than other types of terminals. Push wire into the spring clamp for a secure connection that withstands vibration and temperature changes. Add as many circuits as you need with these terminal blocks and accessories; blocks mount side-by-side on DIN 3 rail.

Use blocks with disconnect tab for testing.

End covers fit on the open side of a block to prevent accidental contact with a live circuit.

End stops mount at the end of a group of blocks to prevent movement.

Adjacent jumpers connect terminals on adjacent blocks of the same width. Alternate jumpers connect terminals on two blocks of the same width, skipping a block in between.

Numbered marker cards include two of each number (1-50).

Note: Prices are 15% lower when you buy 25 or more of the same size.
