Key Ratings and What They Mean for Selection
The 3RT1034-3AP06-ZX95: The AC-2 rating of 15 kW at 400 V defines its capability for switching slip-ring motor loads, where moderate inrush and frequent operation are expected. The AC-4 rating of 29 A at 400 V covers plugging and inching duty, the most severe switching condition for a contactor — this figure governs the maximum current the contacts can interrupt during reverse or jogging cycles. For standard squirrel-cage motor starting (AC-3), the contactor is rated at 18.5 kW at 500 V and 10 kW at 690 V, giving flexibility across common industrial voltage levels.
Mounting and Integration
Mounts via screw fixing or snap-on onto a 35 mm DIN rail per EN 50022. Side-by-side mounting is permitted, which simplifies dense panel layouts without derating for heat buildup when within the rated operating temperature range of -25 to +60 °C. Main circuit terminals are screw-type, accepting solid conductors from 0.25 to 2.5 mm² (2x) and stranded conductors up to 25 mm² (2x). The minimum permissible conductor cross-section at 40 °C is 16 mm², which is relevant for sizing the main power wiring.
Environmental and Compliance
Rated for degree of pollution 3 (conductive pollution typical in industrial enclosures), with IP20 protection on the front and IP00 at the terminals. Storage temperature range spans -55 to +80 °C. The substance prohibitance date of 05/01/2012 aligns with RoHS compliance requirements.
