FAQ
Q1. What is the current rating of the Chint NC2-225/4 contactor?
A1. The NC2-225/4 is rated at 225A in AC-3 duty at 400V and up to 250A in AC-1 duty for non-inductive or slightly inductive loads.
Q2. Which coil voltages are available for this model?
A2. The contactor is available with AC coils in 110–127V, 220–240V, and 380–415V ranges. You should specify the required coil voltage when placing the order.
Q3. Can this contactor be used for 3-phase motor control?
A3. Yes. With a 225A AC-3 rating and 4-pole design, it is suitable for heavy-duty three-phase motor starting and stopping, provided it is correctly selected and coordinated with protection devices.
Q4. What standards does the NC2-225/4 comply with?
A4. It meets IEC/EN 60947-4-1 standards for low-voltage switchgear and controlgear.
Q5. How can this contactor be mounted in the panel?
A5. The NC2-225/4 can be mounted vertically or horizontally on a DIN rail or directly on the panel plate, with an inclination tolerance of ±5°, allowing flexible panel layouts.
Q6. What is the expected service life?
A6. Mechanical life is typically 2–3 million operations, with electrical life under AC-3 duty around 0.8–1.2 million operations, depending on load and operating conditions.
