1.Applicable range
1.1 SF series Din-rail mounting type mini change-over switches mainly are suitable for AC 50/60 Hz, rated voltage 230~415V, rated
current 16A to 125A resistance and inductance mixed circuit, a switch for two-way power supply or load conversion electrical appliances,
can realize the conversion function of the circuit and the function of the isolator. Use places such as the switching of the power supply
of electrical equipment, the switching of the solar power and mains supply,the forward and reverse switching of the motor, and the
exchange of voltage and current in the measurement circuit etc. The change-over switches comply with IEC60947-3, EN60947-3
standards.
1.2 Application environment and working conditions.
Ambient air temperature:-25ºC~+40ºC and the average temperature in 24 h shall not exceed +50ºC. Altitude: not over
2000m. Relative humidity of atmosphere: not more than 50% at +50ºC, and not more than 90% in the month with highest
humidity.
Pollution grade: II. Use category: AC-22A.
On symmetrical DIN rail 35mm, Panel mounting
2.Product features
The Din rail mounting type mini transfer switch is directly operated by a handle to achieve the O, I, and II gear conversion function.
The internal handle rotating groove and the sliding part of the shaft are coated with advanced lubricating grease to reduce mechanical
wear. The dynamic and static contacts adopt a reasonable contact form, with good conductivity and stability. Modular and standardized
Din-rail mounting structure, especially suitable for use as a supporting circuit for terminal combination appliances.
