Motor starter PKZM4, Ir=24-32A PKZM4-32-EA 190020

Motor protection switches of the PKZ series – reliable drive protection

The PKZM4-32-EA motor protection switch is a key element in protecting electric motors, providing effective protection against overload and short circuit. The device is designed for stationary mounting and finds application in a wide range of electrical installations – from industrial to commercial. This model, with a rated continuous current of 32A, is perfect for circuits powering motors up to 15 kW (AC-3, 400V).

Design and functionality

The PKZM4-32-EA switch is characterized by a solid construction and precise finishing. The use of screw connections ensures secure and durable electrical connections. The device has three poles, allowing its use in three-phase circuits. The built-in thermal-magnetic release reacts to both overloads and short circuits, providing comprehensive motor protection. Additionally, the phase failure sensitivity increases the safety of the installation, protecting the motor from damage caused by voltage asymmetry.

Applications and benefits

This motor protection switch is an ideal solution for installers and users looking for reliable motor protection. Its versatility allows it to be used in various applications:

• Electric motor protection: Protects against overload, short circuit and phase failure.
• Industry: Ideal for use in production plants, workshops and other industrial facilities.
• Commercial construction: Works well in HVAC systems, pumps, fans and other electrical equipment.
• Easy installation: Thanks to screw connections, installation is simple and quick.
• High reliability: Compliance with IEC/EN60947 standards guarantees long-lasting and trouble-free operation.
• Compact dimensions: Dimensions 55 x 140 x 160 mm allow for mounting in limited space.
• Rated short-circuit breaking capacity: 50 kA at 400 V AC ensures effective disconnection of the circuit in the event of a short circuit.
• Setting range of overload release: Adjustment in the range of 25-32A allows adaptation to specific application needs.
