Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is essential for the following industrial systems and equipment:
| pressure: | Atmospheric (sealed enclosure dependent) |
| other spec: | Humidity: 5-95% non-condensing, Vibration: 5-2000 Hz per IEC 60068-2-6, EMC: IEC 61000-4 series compliance |
| temperature: | -40°C to +85°C (operating), -55°C to +125°C (storage) |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.

CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The Control PCB processes signals from current and voltage sensors, runs protection algorithms, and triggers the trip mechanism when a fault is detected, thereby interrupting the circuit.
The rated voltage range is 24–240 V AC/DC and rated current is 0.5–5 A, per IEC 60947-1. These are reference values; confirm for your specific model.
It operates from -40 to 85 °C, stores from -40 to 105 °C, and tolerates 5–95% relative humidity (non-condensing). Ingress protection depends on the enclosure, typically IP54–IP65.
Always check the datasheet or contact the legal manufacturer or supplier to confirm that the Control PCB meets your required voltage, current, temperature, and other parameters.
