Motor starter switch 6.3A 2.2kW PKZM0-6.3 072738

Motor starter – reliable protection for your motors

This three-pole motor starter PKZM0-6.3 from Eaton is a key element in protecting the electrical installation powering motors. Designed for reliability and durability, it provides effective protection against overloads and short circuits, and also has a built-in phase failure detection function. The device is intended for operation in networks with a voltage of up to 690V AC and has a short-circuit breaking capacity of 150kA, which guarantees safety even in demanding conditions.

Functionality and application

The PKZM0-6.3 starter finds application in a wide range of industrial and commercial applications. The rated power for AC-3 is 2.2kW at 400V, and 1.1kW at 230V, making it an ideal solution for various motor loads. The adjustable overload release range (4-6.3A) allows for precise adjustment to the characteristics of the protected circuit. DIN rail mounting and screw connection ensure easy and safe installation.

• Overload protection: Protects the motor from damage caused by excessive load.
• Short-circuit protection: Immediately interrupts the circuit in the event of a short circuit, minimizing the risk of fire and equipment damage.
• Phase failure sensitivity: Detects the absence of one phase and disconnects the power supply, protecting the motor from operating in incorrect conditions.
• Wide voltage range: Operation in networks up to 690V AC ensures compatibility with various electrical installations.
• High short-circuit breaking capacity: 150kA capacity guarantees effective protection even with high short-circuit currents.
• Easy installation: DIN rail mounting and screw connection facilitate installation and servicing.

Construction and parameters

The starter is designed with durability and reliability in mind. The fixed construction of the device and the IP20 degree of protection ensure resistance to environmental conditions. The thermomagnetic tripping method guarantees a quick and precise reaction to electrical hazards. The use of a screw connection ensures a secure and durable connection of the wires, minimizing the risk of loosening connections during operation. Additionally, compact dimensions (76 mm depth, 45 mm width, 93 mm height) allow for easy adaptation to existing electrical infrastructure.
