Product Overview:
A heating circuit is a power switching circuit supplying one or more resistive heating elements switched by a contactor. The same general rules apply as for motor circuits, except that heating circuits are not normally subjected to overload currents. It is therefore only necessary to provide short-circuit protection. The variation in resistance values between hot and cold states causes a current peak at switch-on which never exceeds 2 to 3 times the rated operational current (In). This initial peak does not recur during normal operation where subsequent switching is thermostatically controlled. The rated power and current of a heater are given for the normal operating temperature.

Protection:
The steady state current drawn by a heating circuit is constant when the voltage is stable. In fact:
• It is unlikely that the number of loads in an existing circuit will be modified
• This type of circuit cannot create overloads. It is therefore only necessary to provide short-circuit protection.
This can be provided by:
• GG type fuses, or
• Modular circuit breakers.
Nevertheless, it is always possible and sometimes more economical (smaller cable size) to protect the circuit by a thermal overload relay and associated aM type fuses.
Switching, control, protection:
A heating element or group of heating elements of a given power may be either single-phase or 3-phase and may be supplied from a 220/127 V or a 400/230 V distribution system. Excluding a single-phase 127 V system (which is no longer commonly used), the following 3 types of circuit arrangement are possible:
• Single-phase, 2-pole switching
• Single-phase, 4-pole switching
• 3-phase switching
