Frequently Asked Questions

QWhat is the rated insulation voltage of CJX1 / 3TF series AC contactors?

The rated insulation voltage varies by model. For smaller models (CJX1-9F to CJX1-38, 3TF30–3TF45), the rated insulation voltage is 690V. For larger models (CJX1-45 and above, 3TF46–3TF56), the rated insulation voltage is 1000V, making them suitable for a wider range of industrial power systems.

QWhat is the difference between AC-3 and AC-4 rated operational current?

AC-3 refers to the rated current for normal motor starting and switching off during running (squirrel-cage motors), while AC-4 applies to plugging, inching, and reversing duties which involve higher breaking currents. For example, the CJX1-9F (3TF30) has an AC-3 current of 9A but 3.3A under AC-4 conditions at 380V.

QCan auxiliary contact blocks be attached to the CJX1-F series AC contactors?

Yes. Auxiliary contact blocks may be attached to CJX1-F (3TF30–50) series AC contactors. The conventional thermal current for auxiliary contacts is 10A across all models, and the rated operational current for auxiliary contacts (AC-15, 380/220V) is 4–6A or 6–10A depending on the specific model variant.

QWhat coil voltage tolerance is acceptable for CJX1 / 3TF series contactors?

The coil voltage tolerance for all models in the CJX1 / 3TF series is (0.8～1.1)Us, meaning the coil will operate reliably within 80% to 110% of the rated supply voltage. This ensures stable performance even with minor voltage fluctuations in the power supply.

QWhat is the expected mechanical and electrical endurance life?

The mechanical endurance is 15×10⁶ operations for smaller models (CJX1-9F to CJX1-22F, 3TF30–3TF43), and 10×10⁶ operations for larger models (CJX1-32 and above). The electrical endurance under AC-3 duty is 1.2×10⁶ operations, and 0.2×10⁶ operations under AC-4 duty for all models.

QWhat structural advantages improve reliability in compact cabinets?

The CJX1 / 3TF series features an enclosed arc chute made of unsaturated resin for excellent arc resistance, a compact design with small arc-over distance suitable for compact electric cabinets, a unique main contacts system for minimal abrasion and long electrical endurance, and SIGUT (Siemens patent) terminals for easy, reliable, and shock-resistant wiring connections.
