FAQ
Q1. How do I choose between NXC-09, 12, 16, 18, and 22?
Select the model based on the motor's full-load current and application duty. For most AC-3 motor loads, choose the contactor with a rated current equal to or higher than the motor FLA.
Q2. What coil voltages are available?
The NXC series is available with AC coils such as 24V, 48V, 110V, 220V, 380V, and 415V. You should match the coil voltage to the control supply used in your panel.
Q3. Are both 3-pole and 4-pole versions available?
Yes, the series includes 3P and 4P options. 3-pole is common for 3-phase motors; 4-pole is useful for neutral switching or special control circuits.
Q4. What auxiliary contacts are provided?
Most models are available with 1NO + 1NC or 2NO + 2NC auxiliaries. These are used for signaling, interlocking, or logic control.
Q5. Can these contactors be mounted on a DIN rail?
Yes, NXC contactors are designed for DIN rail and screw mounting, making them suitable for standard control panels.
Q6. Are they suitable for harsh ambient conditions?
They operate in a normal range of -5°C to +40°C and can withstand extended limits from -35°C to +70°C when installed as per manufacturer instructions.
