Tips: Working conditions of miniature circuit breakers
- The upper limit of ambient temperature should not exceed +40℃, the lower limit should not be lower than -5℃, and the average temperature of 24h should not exceed +35℃.
- The altitude of the installation site does not exceed 2000m.
- The relative humidity of the atmosphere does not exceed 50% when the ambient air temperature is +40℃. Higher relative humidity can be allowed at a lower temperature, for example, up to 90% at +20℃. Appropriate measures should be taken for condensation.
- The external magnetic field of the installation site should not exceed 5 times the geomagnetic field in any direction.
- The miniature circuit breaker is generally installed vertically, with a tolerance of 2° in any direction.
- There should be no significant impact and vibration at the installation site.
Cost-effective 2 pole miniature circuit breaker with 6 amp rated current, C curve trip characteristic, DIN rail mounting, meets IEC standard and can be safely used in AC 50Hz, 230/400V with a 6 kA short circuit withstand rating.
