How water 3 phases heater connect?

A three-phase water heater connects to a three-phase power supply, where each phase provides a separate current to the heating elements. The heater typically has three heating elements, one for each phase, allowing for balanced load distribution. Each element is wired to a contactor or relay that controls the power supply based on the thermostat settings. Proper installation requires adherence to electrical codes and safety standards to ensure efficient operation and prevent overload.
