Details: The JCH2-125 has a rated making as well as breaking capacity of 3le, 1.05Ue, COSØ=0.65. This ensures reliable operation when switching circuits on and off, even under load.

6. Insulation Voltage (Ui)

What It Is: Insulation voltage is the maximum voltage that can be applied between live parts and the ground or between different live parts without causing insulation failure.

Details: The JCH2-125 has an insulation voltage rating of 690V, indicating ability to provide effective insulation in electrical circuits up to this voltage.

7. IP Rating

What It Is: The Ingress Protection (IP) rating measures the degree of protection the device offers against dust, water, and other environmental factors.

Details: The JCH2-125 has an IP20 rating, meaning it is protected against solid objects greater than 12.5mm in diameter and is not protected against water. It is good for environments where dust protection is necessary but water ingress is not a concern.

8. Current Limiting Class

What It Is: The current limiting class indicates the device’s ability to limit the amount of current that flows through it during fault conditions, thereby reducing potential damage.

Details: The JCH2-125 falls into Current Limiting Class 3, which signifies its effectiveness in limiting the current and protecting the circuit.
