Motor starter PKZM01, Ir=2.5-4A PKZM01-4-EA 189887

Motor starter – reliable motor protection

This three-pole Eaton PKZM01-4-EA motor starter is a key element in protecting electrical installations powering motors. It provides comprehensive protection against overload and short circuit, guaranteeing safe and reliable operation of devices. The thermomagnetic design combines the advantages of a thermal release (overload protection) and a magnetic release (short-circuit protection), which translates into a long service life and minimal failure rate.

Functionality and application

The PKZM01 starter is designed to protect motors with a power of up to 1.5 kW at 400V and 0.75 kW at 230V. The setting range of the overload release (2.5 – 4 A) allows for precise adjustment to the load characteristics. Phase failure sensitivity further increases safety, protecting the motor from damage caused by voltage asymmetry. The starter finds application in a wide range of industrial, commercial installations and in public buildings.

Key features and benefits

• Wide range of applications: ideal for protecting motors up to 1.5 kW (400V) and 0.75 kW (230V).
• Precise protection: overload release setting range of 2.5 – 4 A allows adaptation to a specific load.
• High short-circuit breaking capacity: 50 kA at 400 V AC provides effective protection in the event of a short circuit.
• Phase failure sensitivity: additional protection of the motor against damage caused by the loss of one phase.
• Solid construction: permanently mounted device made of high-quality materials guarantees durability and reliability.
• Easy installation: screw connection of the main contacts facilitates and speeds up installation.
• Compact dimensions: width of 45 mm allows for mounting in tight switchgear spaces.
• Protection class IP20: provides basic protection against accidental contact and access to live parts.

The PKZM01 starter is characterized by a rated continuous current of 4A and a short-circuit breaking capacity of up to 50 kA at 400V AC. Its rated operating voltage is 440V, and the setting range of the overload release is 2.5 - 4 A. The device allows for the protection of motors with a power of up to 1.5 kW at 400V and up to 0.75 kW at 230V. The dimensions of the starter are: width 45 mm, depth 93 mm and height 90 mm.

The PKZM01 starter is a proven choice for installers looking for a reliable and effective solution for protecting electric motors. Its solid construction and precise parameters ensure long-term and safe operation of the installation.
