Description

TeSys K control relay, 4 contacts (3NO + 1NC), 10A/690V, for control of electromagnetic loads AC-15/DC-13. It provides a 24V DC control circuit with no inrush consumption, connection by screw clamp terminals. For high operating rates until 180 cycles/min and ambient temperature -25/+50°C, it procures high reliability and durability. Compact (45mm width), for clipping on 35mm DIN rail or fixing by screw. Multi standards certified (IEC, UL, CSA, CCC, EAC).

Features

Featuring three Normally Open (NO) and one Normally Closed (NC) instantaneous contacts rated at 10 Amps, this control relay allows industrial panel builders to seamlessly manage simultaneous power-pole signaling and safety interlocking. This specific 4-pole contact split optimizes control circuit topology, eliminating the need for bulky auxiliary contact add-ons in complex motor starter configurations.
Built with a highly efficient 24V DC control coil that consumes only 3 Watts during operation, this relay can be driven directly by standard PLC solid-state outputs without the risk of overcurrent damage to your controller. The integrated bi-directional peak-limiting diode suppressor protects sensitive upstream automation electronics from dangerous transient voltage spikes during coil de-energization.
Measuring just 45mm in width, this miniature control relay delivers full-scale industrial reliability within an ultra-compact housing. It mounts effortlessly onto standard 35mm DIN rails or can be panel-screwed directly to a backplate, allowing automation engineers to maximize rail space and shrink overall enclosure dimensions without sacrificing electrical clearance.
Engineered to withstand up to 10,000 operating cycles per hour under maximum mechanical loads, the CA3KN31BD is purpose-built for high-duty-cycle industrial environments like packaging, sorting, and conveyor systems. This high mechanical longevity translates directly into reduced machine downtime and fewer preventative maintenance interventions over the lifespan of your control panel.
