FAQ
Q1. What is the rated current of the Chint NC2-150 4P contactor?
A1. The NC2-150 is rated at 150A in AC-3 duty at 400V and up to 200A in AC-1 duty for non-inductive or slightly inductive loads.
Q2. Which coil voltage is supplied in this model on RadicalTechMart?
A2. This specific listing is for the 48V DC coil variant. Other coil voltages like 110–127V AC, 220–240V AC, and 380–415V AC or 110V/220V DC are available on request as separate models.
Q3. Can this contactor be used for 3-phase motor starting?
A3. Yes. With a 150A AC-3 rating and 4-pole configuration, it is suitable for heavy-duty three-phase motor starting and stopping, subject to proper selection and coordination with protection devices.
Q4. What standards does the NC2-150 comply with?
A4. The contactor conforms to IEC/EN 60947-4-1 standards for low-voltage switchgear and controlgear.
Q5. How is the contactor mounted in the panel?
A5. The NC2-150 can be mounted vertically or horizontally on a DIN rail or directly on the panel plate, depending on your panel layout and accessories.
Q6. What is the expected service life of this contactor?
A6. The mechanical life is typically in the range of 2–3 million operations, while the electrical life under AC-3 duty is around 0.8–1.2 million operations, depending on load and operating conditions.
