Motor starter PKZM01, Ir=4-6.3A PKZM01-6.3-EA 189888

Motor starter – reliable motor protection

This three-pole Eaton PKZM01-6.3-EA motor starter 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 elements of the circuit. Its compact dimensions (93 mm depth, 45 mm width, 90 mm height) allow for easy installation even in limited space.

This starter is designed to operate in circuits with a rated voltage of 440 V AC and a continuous current of up to 6.3 A. The rated short-circuit breaking capacity at 400 V AC is as high as 50 kA, which guarantees a quick and safe response in the event of a failure. Characteristic C allows it to react more slowly to short current surges, so it tolerates starting devices with a motor well.

Design and functionality

The PKZM01-6.3-EA starter is distinguished by a solid construction of a permanently mounted device. It has a screw connection of the main contacts, which ensures a secure and durable connection of the wires. It is also equipped with phase failure sensitivity – an important function that increases the safety of motor operation. Thermal protection is not integrated, but the device effectively protects against the effects of overloads.

Application and benefits

The PKZM01-6.3-EA motor starter finds application in a wide range of industrial and commercial applications:

• Motor protection: Protects electric motors from damage caused by overload or short circuit.
• Motor starters: It is compatible with the DILM series of contactors from Eaton, enabling the construction of efficient motor starters.
• Industrial installations: Ideal for use in production plants, workshops and other industrial facilities.
• Commercial buildings: Can be used in HVAC systems, pumps and other equipment requiring motor protection.

Thanks to compliance with IEC/EN60947 standards and IP20 degree of protection, the starter ensures reliable operation even in difficult environmental conditions (operating temperature: -25°C to +55°C). The rated power for AC-3 is 2.2 kW at 400 V and 1.1 kW at 230 V – making it a suitable choice for many typical motor applications. Power loss is 5.68 W.
