Detailed introduction：

Product description

SMGQ1-63M dual power automatic switch to open the United States for the exchange of 50Hz, rated voltage 400V, rated current 63A the following dual power supply system: According to the need for two-way power supply between the selective conversion: the product has overload, short circuit , But also has the output closing signal function: especially for office buildings, shopping malls, banks, high-rise buildings and other lighting lines used.

Products comply with IEC60947-6-1RGB / T14048.11 standards

Model and meaning

Main feature

○ anti-interference ability, high precision.

○ Protection function is complete, with overload, short circuit protection.

○ small size, high breaking, arc short, compact structure, beautiful appearance.

○ noise-free operation, energy saving, easy to install simple operation, stable performance.

Normal operating conditions

Ambient air temperature upper limit does not exceed +40 ℃, the lower limit does not exceed - 5 ℃. 24h the average does not exceed +35 ℃. The altitude of the installation site shall not exceed 2000m. The relative humidity of the atmosphere in the ambient air temperature +40 ℃ not more than 50%, at low temperatures, you can have a high humidity; the wettest month average minimum temperature of +25-C, the average maximum, the relative The degree of humidity was 90%. And taking into account the humidity change occurs in the product surface of the cream, should take special measures. Pollution level for the III level. No strong vibration and shock, no corrosive and destructive insulation gases, no serious dust, no conductive particles and explosive hazardous substances, no strong electromagnetic interference.

Operation and wiring

According to the actual needs of the design circuit connected to the common power supply and standby power supply of the progress of the line, the zero line and ground. The terminals of the two circuit breakers are connected in parallel, but the phase sequence must be the same (see wiring diagram).

When the circuit breaker is 3 poles, the zero wire must be connected to the zero wire terminal of the change-over switch (common zero wire and spare zero wire are respectively connected to the 2 # and 4 # terminals).

Connecting and breaking capacity

Note: The AC-33B does not frequently operate the motor under the charge or contains the motor, the resistance load is less than 30% of the incandescent lamp is responsible for the mixed load.
