R Series: main features
The features and the use of the best standard of materials assure the quality, reliability and safety of breter cam-switches, as confirmed by the approvals granted by the most important international test houes.
Two-position switches used to connect and disconnect any electrical supply. They are used in a variety of power switchig applications like manual control of direct on-line motors and isolation of motor branch circuits.
Three-position switches used in power applications to change between alternate electrical supplies. Changeover switches are typically used to switch the power supply from the primary source to a stand-by generator or emergency supply in the event of a power outage.
Multi-position switches used to connect a variety of loads to an electrical supply in a predeterminated logical sequence. A typical application would be temperature control of a heating oven or furnace.
Three-position (Forward, Off, Reverse) switches used to manually control the direction of rotation of a motor. Operating the switch changes the wiring configutation to the motor to operate in the forward or reverse direction.
Three-position (1st speed, off, 2nd speed) switches
used to select 2 different speeds of rotation of a motor. Operating the switch
changes the wiring configutation and the number of poles of the motor (i.e.
4/2, 8/4, etc.)
The second speed is always two times the first one.
Star Delta switch (Wye-Delta)
Three-position (Off, Wye, Delta) switches used to manually control the reduced voltage starting of a motor. Operating the switch changes the wiring configutation to the motor from a star configuration to a delta configuration once the person operating the controller determines the motor is up to speed.
Multi-position switches used to connect one or more phases of the electrical supply to an ammeter, so that the current in each phase can be displayed on the ammeter.
Multi-position switches used to connect two lines of the electrical supply system to a voltmeter, so that the voltage between lines (phase-to-phase or phase-to-neutral) can be displayed on the voltmeter.
