The reference temperature for the circuit breaker is +30°C. When the ambient temperature changes, its rated current value needs to be corrected.

• The altitude of the installation site shall not exceed 2000m.

• The relative humidity of the atmosphere at the installation site shall not exceed 50% at the maximum surrounding temperature of +40°C. Higher relative humidity is permissible at lower temperatures. The monthly average maximum relative humidity of the wettest month shall not exceed 90%, and the monthly average temperature of that month shall not exceed +25°C. Measures must be taken against condensation that may occasionally occur on the product due to temperature changes.

• Pollution degree 2.

• Installation category II.

• The circuit breaker is mounted using the TH35-7.5 standard mounting rail.

• The circuit breaker should generally be mounted vertically, with the handle in the upward position indicating the power-on state.

• The installation location of the circuit breaker shall be free from significant impact and vibration.

• For products with an N-pole, when wiring, the neutral line must be connected to the pole marked with the N-pole identifier.

• The circuit breaker must not be dropped or exposed to rain during use, storage, or transportation.
