The CA2KN31P7 is an auxiliary relay with a compact DIN rail-mounted design, measuring approximately 45x57x58 mm. It features a control coil operating at 230 V AC (50/60 Hz) and provides four contacts: three normally open (NO) and one normally closed (NC). The relay is suitable for controlling electromagnetic loads up to 690 V AC-15/DC-13 and can be expanded with auxiliary switch blocks for flexible system integration. It offers a cost-effective solution for simple control applications and shares a similar design to other Schneider Electric contactors such as the TeSys D, K, and SK series.
