The cage clamp termination is a spring-loaded connection that accepts solid or ferruled stranded conductors without retightening — useful in high-vibration panels or where maintenance access is limited. Rated for top-hat rail (DIN rail) fixing, Size S00 footprint. This is the smallest SIRIUS contactor relay frame, so it fits tightly packed control cabinets where every millimeter of DIN rail counts. The 60 V DC coil is a less common voltage — verify your control supply matches before specifying. Most standard panels run 24 V DC; this part is for legacy or specialized 60 V DC control circuits.","metaTitle":"3RH1140-2BE40-0AA6 Contactor Relay, 4NO, 60 V DC, Cage Clamp","metaDescription":"Siemens 3RH1140-2BE40-0AA6 contactor relay, 4NO, 60 V DC coil, cage clamp connection, Size S00, DIN rail.
