Motor starter PKZM0, Ir=0.1-0.16A PKZM0-0.16-EA 189894

Motor starter switches PKZM0 – protection and reliability in every circuit

The PKZM0 motor starter switch is a compact and reliable device designed to protect electric motors from overloads and short circuits. Model PKZM0-0.16-EA, with an overload release setting range of 0.1-0.16A, is perfect for applications requiring precise protection of circuits with low current consumption. The device combines thermal and magnetic protection functions, providing comprehensive protection of the installation.

Construction and mounting

The PKZM0 switch is characterized by a solid construction for mounting on a DIN rail. Screw terminals guarantee a secure and durable connection of wires. Compact dimensions (width 45 mm, height 93 mm, depth 76 mm) allow for easy integration with existing switchboards. The device complies with IEC/EN 60947 and VDE 0660 standards, confirming its high quality and safety standards. Additionally, PKZ switches are compatible with the DILM series of contactors from Eaton, making it easier to create complete starter systems.

Application and benefits

The PKZM0-0.16-EA switch finds application in a wide range of industrial and commercial applications, including:

• Protection of electric motors in HVAC (heating, ventilation, air conditioning) equipment.
• Protection of circuits powering pumps, fans and other low-current devices.
• Transformer protection – a dedicated model for protecting transformers.
• Industrial installations requiring reliable protection against overloads and short circuits.

Key product features:

• Wide adjustment range: The adjustable overload release range (0.1 - 0.16 A) allows precise adjustment to the load characteristics.
• High breaking capacity: The rated short-circuit breaking capacity Icu at 400 V AC is as high as 150 kA, ensuring effective protection in the event of a short circuit.
• Phase failure sensitivity: The built-in phase failure sensitivity function protects the motor from damage caused by the loss of one of the supply phases.
• Thermal-magnetic tripping method: The combination of thermal and magnetic protection provides comprehensive protection against various types of failures.
• Safety and compliance with standards: Compliance with IEC/EN 60947 and VDE 0660 requirements guarantees safe use and compliance with applicable regulations.
• Durability: Robust construction ensures long-lasting and trouble-free operation of the device.
• Power loss: Low power loss of 5.39 W contributes to efficient energy use.

PKZ motor starter switches are a tradition of innovation dating back to 1932 – a proven solution for demanding users who value the reliability and safety of electrical installations.
