10A Terminal Blocks with Spring Clamp Provide Quick and Easy Termination

The METZ CONNECT portfolio of terminal blocks for mounting on a circuit board now includes the ASP045 series of spring-clamp blocks, which have a 5mm centerline, and offer between two and 24 poles.

Rated for current up to 10A, the ASP045 terminal blocks are compatible with wire sizes in the range AWG 28 to AWG 16.

Featuring a patented cage clamp design, the ASP045 blocks are particularly easy to terminate, helping to improve efficiency and throughput in production environments. No screwdriver or other tool is needed to make a termination: the ASP045 is supplied with an open ‘wire-ready’ terminal chamber.

The spring clamp provides a consistent connection - the spring automatically adjusts to different size wires.

Safety attributes of the ASP045 terminal blocks include a creepage and clearance distance of 4mm, minimum insulating strip length of 4mm, and the use of CTI 400 class insulating material.
