Description

The RCB 200340 will be required to be used together with FCU controller – ECF4326565 when directly control chilled water Fan Coil Unit with single phase 240VAC fan motor capacity greater than 0.4kw. The RCB 200340 has on-board high current rating relay contacts for fan high speed mode, fan medium speed mode and fan low speed mode. Each relay contact capable of switching up to 30 amps (maximum) at 240VAC. Together with RCB 200340, the FCU controller – ECF4326565 can be used to directly control chilled water Fan Coil Unit with single phase 240VAC fan motor capacity not greater than 2kw.

With on board temperature sensor and current sensor built on to the RCB 200340 which will be physically connected to the FCU controller – ECF4326565, additional safety features such as high temperature or high current output total shutdown can be implemented to provide more secure and risk free operation.

The on board 20 amps fuse on the RCB 200340 will design as ultimate protection against direct shorting or fan motor jammed situation.

  • 3 x High Contacts Output Capable To Switch Up To 30A @ 240 VAC
  • On-Board Temperature Sensing (-10°C – 60°C) & Current Sensing (0A – 20A)
  • Input Short Circuit Current Protection Via 20A Fuse
  • Power Supply – 240 VAC
  • Surface Mount Device (SMD)
  • High Current Output Switching To Support Up To 2kW Single Phase 240VAC Three Speed Fan Motor
  • On-Board Temperature Sensing High / Low Alarm Monitoring Including Programmable Output Shutdown
  • On-board Input High Current Alarm Monitoring Including Programmable Over Current Output Shutdown

The RCB 200340 can be used for other applications such as:

  • Opening / Closing directly motorized garage door roller shutter.
  • On / off directly high current lighting circuit.
  • On / off directly any single phase 240VAC motor
