Thermal dissipation is 5.7 W per pole, which sums to 17.1 W for three poles — this heat load must be factored into the enclosure ventilation calculation to keep the ambient below the 70 °C operating limit. ## Termination, tooling, and environmental limits Main circuit terminals are screw-type (hexagonal socket, 4 mm hexagon tip), accepting solid conductors 2x (2.5... 16 mm²) and stranded conductors 2x (6... 16 mm²), 2x (10... 50 mm²), or 1x (10... 70 mm²) — the M8 screw size handles the larger cable lugs typical of the S3 frame. Mounting position is any orientation, giving flexibility in crowded panels. ## Lifecycle and sourcing — active production, quoted to order RoHS compliance date is 03/01/2017, meeting the EU substance restriction deadline.","metaTitle":"Siemens 3RU2146-4JD0 SIRIUS Overload Relay, CLASS 10, S3","metaDescription":"Siemens 3RU2146-4JD0 SIRIUS thermal overload relay, CLASS 10 trip, S3 size, 690 V rated, screw terminals.
