Motor Starter Protectors/Circuit Breakers Block 3RV11 With (2NO+2NC)

uses :-
The 3RV1 motor starter protectors can be used:
1. For short-circuit protection
2. For motor protection (also with overload relay function)
3. For system protection
4. For short-circuit protection for starter combinations
5. For transformer protection
6. As main control and EMERGENCY-STOP switches
7. For fuse monitoring
8. For use in IT systems (IT networks)
9. For switching of DC currents
10. As voltage transformer circuit breakers
11. In areas subject to explosion hazard (ATEX)

This Motor Starter Protectors/Circuit Breakers Block is easily insert in your schematic diagram and connect as you like way.

3RV1 motor starter protectors are suitable for use in any climate. They are intended for use in enclosed rooms in which no severe operating conditions (such as dust, caustic vapors, hazardous gases) prevail. When installed in dusty and damp areas, suitable enclosures must be provided. 3RV1 motor starter protectors can optionally be fed from the top
or from below. The permissible ambient temperatures, the maximum switching capacities, the tripping currents and other boundary conditions can be found in the technical specifications and tripping characteristics. 3RV1 motor starter protectors are suitable for operation in IT systems (IT networks). In this case, the different short-circuit breaking
capacity in the IT system must be taken into account. Since operational currents, starting currents and current peaks
are different even for motors with identical power ratings due to the inrush current, the motor ratings in the selection tables are only guide values. The specific rated and start-up data of the motor to be protected is always paramount to the choice of the most suitable motor starter protector. This also applies to motor starter protectors for transformer protection.
Three-phase busbar systems provide an easy, time-saving and clearly arranged means of feeding 3RV1 motor starter protectors with screw terminals. Different versions are available for sizes S00, S0 and S2 and can be used for the various different types of motor starter protectors. The 3RV19 15 three-phase busbar systems are not suitable for 3RV11 motor starter protectors with overload relay function.
Motor starter protectors with a rotary operating mechanism can be mounted in a control cabinet and operated externally by means of a door-coupling rotary operating mechanism. When the cabinet door with motor starter protector is closed, the operating mechanism is coupled. When the motor starter protector closes, the coupling is locked which prevents the door from being opened unintentionally. This interlock can be defeated by the maintenance personnel. In the open position, the rotary operating mechanism can be secured against reclosing with up to 3 padlocks. Inadvertent opening of the door is not possible in this case either.
