Thermostats and controls
Other equipment which doesn’t necessarily need to be connected directly to heating is also used for regulation. This includes, for example, regulators for attenuation temperature and programmable timer switches which work together with other regulation elements or devices which disconnect certain appliances (circuits) in the case of a “consumption peak” and thus lower the size requirement for the main circuit breaker of a building.
The HJ 306RX type series measures the current in all three phases; however, it has three independent regulation channels available (one for each phase), with the option of controlling two groups of appliances per channel.
BMR HJ is a device which monitors the alternating current which passes through it and indicates its exceedance by the disconnection of the relevant relay contact.
