Telemecanique Schneider CA2SK20 Control Relay

The Telemecanique Schneider CA2SK20 is a compact SK mini-control relay designed for reliable control of electrical circuits in industrial and commercial applications. This relay allows electrical current to flow through a conducting coil to open or close a switch, making it ideal for controlling electromagnetic loads. With two normally open (2NO) contacts and a rating of 10A at 690V, it offers high versatility in controlling general-purpose and heavy-duty applications. The CA2SK20 is certified to multiple standards, including IEC, UL, CSA, CCC, and EAC, and is a Green Premium product.
