How about a manual switch on a automatic modular contactor?

BCH8 Manual / Automatic modular contactor

Modular Contactor is widely used in lighting, heating, ventilation equipments etc, which applied to comunicate 50Hz/60Hz, rated working voltage up to 400V.In the power system with rated working current of up 100A, AC-1 and AC-7a (non-inductance or low inductance load, resistance furnace, household appliances and similar low inductance load) can be used as long-distance switch and control circuit, and can also be used to control the load of household motor.

But in some occasions ,we need better operating choices when it comes to stepped electricity prices.

In northern China, Manual / Automatic modular contactor are widely used in energy storage heaters that use electricity for heating. In order to protect the environment, the northern heating method was changed from coal to electricity heating. Energy storage heaters equipped with manual contactors turn on heaters during low periods and turn off heaters during peak periods to save energy.

In France, Manual / Automatic modular contactor are widely used to control the heating of hot water also. Electric water heaters pre-set heating during the trough and cut off heating during the peak. In this state of use, when the hot water is insufficient, the contactor can be manually closed to start heating.
