Systemair single phase auto transformer rated from 3.0 amps max, c/w thermal cut out connection.
Single phase transformer which controls the fan speed by altering the supply voltage in five fixed steps. An integral motor protection device is included which cuts the supply voltage to the fan if the thermal contact in the fan motor is activated.
The RTRE has input terminals for room thermostat RT, which stops the supply voltage to the fan when the circuit is broken. The transformer has 230V terminals for operating dampers, electric water-heater batteries or other external equipment.
These terminals have no current when the transformer knob is in position 0, or when the TK or RT input is open. The indicator lamp on the front shows when the transformer is in operation. The fuse may be reset from outside.
• Supply voltage: 230V 50/60Hz.
• Self-extinguishing thermoplastic casing.
Commercial Thermostat, try the TH-16
For the non thermal cut-out version, try the RE
