Motor starter PKZM0 Screw/Push-in 4..6.3A PKZM0-6.3-SPI32 199197

Motor starter – reliable protection for your motor

This three-phase motor starter PKZM0-6.3 from Eaton is a key element in protecting electric motors. It provides effective protection against overloads and short circuits, guaranteeing long-term and trouble-free operation of devices. The device combines thermal-magnetic functions, which means it reacts to both slow temperature increases (overload) and sudden current surges (short circuit). This protects the motor from damage in various situations.

Quick installation and universal connections

The PKZM0-6.3 starter is distinguished by two types of wire connection: screw and innovative Push-in. Push-in technology allows for quick and safe connection of wires without tools – just one click! This solution reduces cabling time by up to 50% and provides resistance to vibrations and shocks. In addition, the device is compatible with existing accessories with screw terminals, which facilitates the modernization of installations. The ability to connect wires both with screws and springs (Push-in) provides great flexibility during installation.

Key features and parameters

The rated continuous current is 6.3 A, which means the maximum current that the starter can conduct continuously without risk of damage. The setting range of the overload release is 4…6.3 A, allowing precise adjustment of sensitivity to the load characteristics. Characteristic C allows it to react more slowly to short current surges, therefore it tolerates starting devices with a motor well. The rated short-circuit breaking capacity (Icu) is 150 kA at 400 V AC, guaranteeing effective disconnection of the circuit in the event of a short circuit with high energy. The device operates in a wide range of voltages – from 690 to 690 V – ensuring compatibility with various electrical installations. It has phase failure sensitivity, protecting the motor from damage caused by the absence of one of the supply phases. The rated operating power for AC-3 is 2.2 kW at 400 V and 1.1 kW at 230 V, determining the maximum power of the motor that can be protected by this starter. Protection class IP20 provides protection against finger contact and access to dangerous components. The device is designed for mounting on a DIN rail in an electrical switchboard as a permanently mounted element.

The PKZM0-6.3 starter is a proven choice for both professional installers and end users looking for reliable protection for electric motors. Its compact dimensions (45 mm wide, 75 mm deep and 102 mm high) allow for easy integration with existing installations. The device meets the IEC/EN 60947 standards, which confirms its high standard of quality and safety.
