Motor starter PKZM0, Ir=1-1.6A PKZM0-1.6-EA 189899

Motor starter switch – reliable motor protection

This 3-pole motor starter switch PKZM0-1.6-EA from Eaton (Moeller) is a key element in protecting electrical installations powering motors. It provides effective protection against overloads, short circuits and phase failure, which translates to a longer lifespan and trouble-free operation of devices. The device is particularly recommended for use in industrial applications where reliability and safety are a priority.

Design and application

The PKZM0-1.6-EA switch is characterized by a compact design and easy mounting on a DIN rail. Screw terminals ensure a secure and durable connection of wires. The device is perfect for protecting motors with a power of up to 0.55 kW at 400V AC and 0.25 kW at 230V AC. Its versatility allows it to be used in a wide range of applications – from simple machines and devices to more complex industrial systems. It is compatible with the DIL series of contactors from Eaton, which makes it easier to create complete motor starters.

Key features and benefits

• High short-circuit breaking capacity: Short-circuit breaking capacity at 150 kA at 400V AC guarantees effective protection of the installation even in the event of serious disturbances.
• Phase failure sensitivity: The built-in phase failure sensitivity function protects the motor from damage caused by the lack of one of the supply phases – this is important to ensure the long-term operation of the device.
• Thermal-magnetic tripping method: The combination of thermal and magnetic protection provides comprehensive protection against various types of failures. Characteristic C allows for short-term overloads, e.g. during motor start-up, without unnecessary tripping of the device.
• Wide current adjustment range: Adjustable overload release setting range (1…1.6 A) allows precise adjustment to the load characteristics and optimization of motor protection.
• Solid construction: Made of high-quality materials ensures durability and reliability of the device even in harsh working conditions (operating temperature: -25°C to +55°C).
• Compliance with standards: Compliance with IEC/EN 60947 standards guarantees safety and compliance with applicable regulations.
• Compact dimensions: Dimensions 93 x 45 x 76 mm allow for easy mounting in a limited space of a switchboard or control cabinet.
