Load separation or Main switches completely separate electrical loads or system components from the electrical supply. They also switch under load or overload. They are used to shut down maintenance work and plant protection. The units in the RH series are modular main circuit breakers with an isolating function and are characterized by their high wear resistance of the contacts. The design enables the use of a switch lock and conforms to the international construction regulations. Features: Modular design; high short-circuit resistance and high switching capacity; double-sided double-level terminals for large conductor cross-section and bus bars; switch position display; jump switching function when switched on; mounting type: Rapid mounting on rail; mounting position random; applications: The RH series devices can be used universally, for example in industrial and building technology or in house installation. Notes: The description of the RH series devices includes both the rated current (first pair of numbers) and the contact design (last pair of numbers), which is listed in the order of NO, NC and CO contact. Thus, a "RH 063-300" has a rated current of 63 A, three NO contact. But no NC or change-over contacts.
