The ambient temperature ranges for the EATON GHG 624 Explosion-Protected Residual Current Operated Circuit Breaker are critical for its safe and effective operation. These ranges, as specified in the instruction manual, vary depending on the size and application category of the circuit breaker. For example, for IIC size 1 to size 4, the operating temperature is between -20°C to +55°C for Serie A and Serie E. For IIB size 1 to size 2, the range is -45°C to +55°C for Serie A and Serie E. Finally, for IIB size 3 to size 4, the operating temperature is between -20°C to +55°C for Serie A and Serie E. These ranges are essential because they ensure the explosion protection parameters are met, defining the maximum permissible temperatures for the enclosure materials. Operating outside of these temperature limits could potentially compromise the functionality and safety of the EATON GHG 624. If your application requires temperatures outside these ranges, it's essential to consult with the manufacturer, Cooper Crouse Hinds, to ensure safe and reliable operation.
