    DZ518(GV2-LS/LE) Electric Motor Protection Circuit Breaker Change-Over Switch Controls

    DZ518(GV2-LS/LE) Electric Motor Protection Circuit Breaker Change-Over Switch Controls


    Product Description:
    DZ518(GV1,GV2,GV3) the series electric motor protection circuit breaker, uses the modular design, the contour is artistic, the volume is small, breaks protects, inside sets Hot Relay, the function is strong, the versatility is good. The DZ518 series conforms to IEC60947.2 and IEC60947-4.1 as well as the EN60947-1 standard. The switch and the contact device may compose the electric motor is direct Starts. The DZ518 series outer covering protection rankmay achieve IP65. This series pooled three types model product: DZ518(GV2-M, ME) is the electric motor belt thermomagnetism protection circuit breaker which the button controls; DZ518(GV2-RS) is the electric motor belt thermomagentism protection circuit breaker which the change-over switch controls; DZ518(GV2-LS,LE) is the electric motor belt magnetism protection circuit breaker which the change-over switch controls (does not bring hot protection).


    Product Advantage:
    ◆ Adjustable current setting value: when used, it can be adjusted to the appropriate current setting value indication position according to the actual working current.
    ◆ Can simulate the tripping design of the mechanism: the mechanism can be tripped by TEST, which is convenient for the simulation test.
    ◆ Front laser marking: the marking content is clear and durable.
    ◆ Double breakpoint structure: double breakpoints of contacts, suppress and disperse arc energy, improve arc extinguishing effect, improve connection breaking capacity, reduce contact electrical losses, effectively improve product electrical life.
    ◆ Thermal magnetic comprehensive protection structure: the product has multiple protection functions of overload, short circuit, three-phase unbalance.

    Working of Circuit Breaker:

    Circuit breakers are made up of pairs of stationary and moving metal contacts, in addition to an operating coil. Under normal cases, when the circuit is closed, these contacts touch each other, allowing an electric current to flow.

    For example, these moving contacts are held together due to mechanical pressure exerted by some other mechanism such as a spring or compressed air. Beneath a closed circuit breaker, current-carrying contacts known as electrodes engage each other due to the pressure of a spring.
    Switching and maintenance of the system are done either by opening or closing the circuit breaker arms. These devices are opened by applying pressure to the trigger. When there is a fault in the current flowing through any part of the system, the breaker’s trip coil is energized, pulling one away from the other, thereby opening the circuit.
