Motor starter PKZM4, Ir=55-63A PKZM4-63-EA 190024

Motor starter – reliable motor protection

This three-pole PKZM4 motor starter, with an adjustable current range of 55-63A, is a key element in protecting electrical installations powering motors. It provides effective protection against overload and short circuit, and its thermal-magnetic tripping method guarantees a quick response in emergency situations. The device's design, intended for permanent mounting, ensures stability and long-term operation.

Characteristics and application

The PKZM4-63-EA starter is designed to protect electric motors in various industrial and commercial applications. Its high rated short-circuit breaking capacity (50 kA at 400V AC) allows for safe disconnection of the circuit in the event of serious disturbances. Phase failure sensitivity further increases safety, protecting the motor from damage caused by voltage asymmetry. The device is particularly useful where protection against overloads resulting from starting motors with high starting torque is required.

Advantages and benefits

• Wide adjustment range: The adjustable overload trip setting range (55-65A) allows for precise adaptation to the load characteristics.
• High breaking capacity: 50kA at 400V AC guarantees effective circuit disconnection in the event of a short circuit, minimizing the risk of damage.
• Phase failure sensitivity: Protects the motor from damage caused by the absence of one of the supply phases.
• Durable construction: The permanently mounted device ensures stability and reliable operation for a long time.
• Easy installation: Screw connection of the main contacts facilitates and speeds up installation.
• Compliance with the new EA series: The starter belongs to the new Eaton EA series, offering a more favorable price while maintaining the same technical parameters as the previous PKZ generation. This allows for economical modernization and device replacement.
• Power for various applications: The rated operating power for AC-3 is 34 kW at 400 V and 18.5 kW at 230 V, making it a universal solution for many applications.

The PKZM4-63-EA starter is a solid and reliable solution for professionals and end users looking for effective protection of electric motors in demanding working conditions. Its modern design and high technical parameters guarantee safe and long-lasting operation.
