    PKZM4 Motor Protective Circuit Breaker Basic Unit


    Eaton's reliable and robust motor protection circuit breakers are the perfect solution for your motor protection needs, providing protection from electrical faults such as an overload of high voltages, short circuits or relay shutdowns. Two motor protection circuit breakers cover the entire PKZ series ranging from 0.1 A to 63 A, storage and space are reduced for simplified engineering with 18 different types.

    Eaton's PKZM4 motor protection range of circuit breakers has been created and designed to act as an intermediary between your devices, protecting vital equipment in the event of unforeseen incidents. This reduces the amount of downtime of machinery to enable operations to continue running smoothly.

    The PKZM4 series are manually actuated circuit breakers featuring a breaking capacity of up to 50kA that make current limiters become almost unnecessary. This motor protection range of circuit breakers has a short circuit breaking capacity rated to 150 kA up to 12 A and 50kA up to 32 A. Accessories including auxiliary contacts, trip indicating auxiliary contacts, voltage release and shunt trips can be installed without tools and greatly reduce installation time.

    The PKZM4 motor protection circuit breakers have been specifically designed for electrical and mechanical compatibility to the DIL contactor series, making them ideal for the configuration of motor starter combinations.

    Features and Benefits


    Larger frame size than the PKZM0, but shares the same accessories e.g. auxiliary contacts Higher switching current: 50kA @ either 230Vac or 400Vac without the need for an upstream current limiter
    Type 1 and 2 co-ordination 55mm width
    The short-circuit release is permanently set to 14 x In; the bi-metal release is set to the relevant full load motor current

    What is a motor protection circuit breaker?


    Electric motors need protection from phase unbalances, current overload and losses, circuit breakers or MPCBs offer motor protection and prevent short circuits by disconnecting the current. Thermal protection guards against overload, magnetic protection protects against short circuits and faults and phase protection guards against phase loss or imbalance. MCPs or motor circuit protectors only protect against short circuits and generally need an overload relay installing, whereas an MPCB doesn't usually need an overload relay offering magnetic protection and preventing thermal overload. MCPBs can also be integrated into a unit with other devices.

    Eaton PKZM4-25 Motor Protective Circuit Breaker


    • Performs the basic function of a protecting your motor
    • Forms part of the PKZM4 motor protection circuit breaker series of up to 65 A
    • Suitable for motors with efficiency class IE3 (IE3-ready devices are identified by the logo on their packaging)
    • The connection technique is through screw terminals
    • The ambient operating temperature when open is 25 - +55 °C
    • The device features an IP20 level of protection, this means that the device is protected against solid objects up to 12 mm, for example, a person's finger. This ingress protection also means that the MPCB has no protection against liquids

    Note

    Eaton formerly known as Moeller


    PKZ Series


    A member of the PKZ family of motor protection circuit breakers. Has a rotary knob for switching on or off, which gives a clear indication of the breaker status.
