Motor starter PKZM4, Ir=40-50A PKZM4-50-EA 190022

Motor starter – reliable protection for motors and installations

The PKZM4-50-EA motor starter is a key element in protecting electric motors, providing effective protection against overload and short circuit. The device is designed for permanent installation and is characterized by high reliability and durability. The construction based on proven Eaton solutions guarantees a long service life and minimizes the risk of failure, which translates to the continuity of installation operation.

Functionality and application

The PKZM4-50-EA starter is widely used in various industries, including motor control systems, pumps, fans and other electrical equipment. It ensures safe operation of devices, protecting them from damage caused by malfunction. Thanks to the adjustable overload release range of 40-50A, the starter is ideal for applications requiring precise adjustment of protection parameters to the specifics of the load. Additionally, the phase failure sensitivity increases the safety of installation operation, preventing damage caused by voltage asymmetry.

Key features and benefits

• Wide range of applications: Rated operating power for AC-3 is 25 kW at 400V and 14 kW at 230V, allowing the starter to be used in various industrial applications.
• High short-circuit breaking capacity: Rated short-circuit breaking capacity Icu at 400 V, AC is as high as 50 kA, which ensures effective protection of the installation in the event of a short circuit.
• Thermal-magnetic tripping method: Provides a quick response to overloads and short circuits, minimizing the risk of damage to connected devices.
• Solid construction: The device made of high-quality materials guarantees durability and resistance to environmental conditions.
• Easy installation: Screw connection of the main contacts facilitates and speeds up the installation process.
• Compact dimensions: Height 140 mm, width 55 mm and depth 160 mm allow the starter to be mounted even in limited space.
• Compliance with standards: Meets the requirements of IEC/EN60947 standards ensuring safety and reliability of operation.
• Versatility: Three-pole design (3P) allows use in three-phase circuits.

Additional information: The starter does not have an integrated undervoltage release or auxiliary contact. Protection class IP20 provides protection against finger contact and against the ingress of solid objects larger than 12.5 mm.
