A built-in disconnect switch allows heaters to disconnect individually in order to perform maintenance tasks. It is a positive and inexpensive way to meet the safety rules. It also reduces the electrical installation costs because the disconnect switch is factory installed. Thermolec strongly recommends that a built-in disconnect switch be specified at all times.
A built-in control transformer is required on most heaters to supply 24 volts to the control circuits. A Class II transformer has built-in safety protection and does not require primary fusing. Primary and secondary fuses can be supplied upon request.
