Heater Failure System

Electronic switches offers heater failure detection controller which detects failures for heater and generate outputs alarm signal. This allows user to take necessary action for replacement of heater well within time. Detection of heater failure is required for varioud applications. In normal case, user understand failure of heater when desired temperature is not reached.

It supports the safe design of heater control systems, and contributes to maintenance improvements for the user. Electronic Switches offers heater failure controller available in Single phase and Three phase type.
