METZ CONNECT AST225 Terminal Blocks

13.5A with spring clamp to provide quick and easy termination

The METZ CONNECT portfolio of terminal blocks for mounting on a circuit board now includes the AST225 series of through-hole spring-clamp blocks, which have a 5mm centerline, and offer between two and 16 poles. Rated for current up to 13.5A, the AST225 terminal blocks are compatible with wire sizes in the range AWG 28 to AWG 16.

Featuring a patented cage clamp design, the AST225 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 AST225 terminal blocks include a creepage and clearance distance of 3.4mm, minimum insulating strip length of 8.5mm, and the use of CTI 600 class insulating material.
