Motor switching capacity and coil voltage
The 3RT2317-2BB40-ZX95: That AC-3 rating governs the real-world motor load it can handle — contactors in this class are typically applied on conveyors, pumps, and fans where the switching frequency stays within the mechanical endurance of 30 million operations. The DC coil draws no holding current once sealed, which simplifies the control transformer sizing in a panel with multiple contactors.
Termination and panel fit
Both the main current circuit and the magnet coil use spring-loaded terminals — no screw torque to verify, no loose strands. The auxiliary switch terminals take the same wire ranges, which keeps the wire inventory consistent across the panel. Side-by-side mounting is allowed — no derating gap needed between units in a row.
Environmental limits and compliance
Minimum relative humidity is 10 %. The contactor is RoHS-compliant with a substance prohibition date of October 1, 2009 — it meets the current EU RoHS directive for new installations. Lifecycle status is current production. This is not a legacy or phase-out part — it is a standard catalog item in the SIRIUS family, quoted to order against your BOM quantity. No direct successor or replacement is needed.
