Motor starter PKZM01, Ir=1-1.6A PKZM01-1.6-EA 189885

Motor starter switch – reliable motor protection

This three-pole motor starter switch PKZM01, with an overload release setting range of 1-1.6A, is a key element in protecting electrical installations powering motors. It provides effective protection against overload and short circuit, protecting both the motor and the other components of the circuit. This is particularly important in industrial and commercial applications where failures can lead to costly downtime.

The PKZM01-1.6-EA switch belongs to the new -EA series from Eaton, which replaces the previous generation in a wide range of applications. This means users can count on modern solutions and full compatibility with existing systems. It is worth noting that the -EA series offers a more favorable price compared to older versions, while maintaining identical technical parameters and dimensions.

Characteristics and application

The switch is designed for fixed mounting and is characterized by a compact design (93 mm depth, 90 mm height and 45 mm width). The thermomagnetic release method guarantees a quick response to sudden current changes, and the phase failure sensitivity further increases work safety. The rated short-circuit breaking capacity of 50 kA at 400 V AC demonstrates the high reliability of the device in the event of a short circuit.

The PKZM01 switch finds application in:

• Protection of electric motors with a power of up to 0.55 kW (AC-3, 400 V) and 0.25 kW (AC-3, 230 V).
• Industrial installations – protection of machines and equipment.
• Commercial buildings – protection of HVAC systems, pumps and fans.
• Applications requiring high reliability and safety of operation.
• Circuits with characteristic C – copes well with starting devices with a motor thanks to the delayed reaction to short-term current surges.

Key features and benefits

• Three-pole design: provides full protection for three-phase motors.
• Overload release setting range: allows precise adjustment to the load characteristics (1…1.6 A).
• Rated continuous current: 1.6 A – ideal for applications with a stable load.
• High breaking capacity: 50 kA at 400 V AC – guarantees safety in the event of a failure.
• Phase failure sensitivity: additional protection against motor damage caused by voltage asymmetry.
• Screw connection: ensures a secure and durable connection of wires.
• -EA series: more favorable price while maintaining the same technical parameters as the previous generation of PKZM01 switches.
• Power loss: Low power losses of 5.36 W translate into energy savings during device operation.
