Eti-Polam CEM65CN.10 Capacitor Contactor 50kvar 230V AC 1NO

The Eti-Polam CEM65CN.10 is a specialized capacitor contactor engineered for the reliable switching of power factor correction capacitors. Designed to manage the high inrush currents inherent in capacitor bank operations, this device ensures stable performance and extended service life in demanding industrial electrical environments. It operates with a control voltage of 230V AC and includes one normally open auxiliary contact for integration into control circuits.

Advantages

This contactor provides superior durability by effectively mitigating the stress caused by transient current peaks during capacitor energization. Its robust construction is specifically optimized for power factor correction systems, reducing the risk of contact welding and ensuring consistent electrical connectivity. The inclusion of an auxiliary contact allows for seamless monitoring and integration within complex automation or power management setups.

Suitable for

• Power factor correction capacitor banks
• Industrial electrical distribution systems
• Reactive power compensation panels
• Automated electrical control circuits

This device is not intended for general motor control or standard resistive load switching, as its internal design is specifically calibrated for the unique electrical characteristics of capacitive loads. It should not be used in applications where the required reactive power exceeds the rated capacity of 50kvar.

Key specifications

• Rated power: 50kvar
• Control voltage: 230V AC
• Auxiliary contact configuration: 1NO (Normally Open)
• Application: Capacitor switching

Installation should be performed by a qualified electrician in accordance with local electrical codes. The contactor is mounted on a standard DIN rail or via screw mounting within an electrical enclosure. Ensure that the control circuit voltage matches the 230V AC specification before connecting the coil terminals. Verify that all power cables are securely fastened to the main terminals to prevent overheating during operation.

What to consider before purchase

• Verify the total reactive power of your capacitor bank does not exceed 50kvar
• Ensure the control system provides a 230V AC signal
• Check available space within the electrical cabinet for mounting
• Confirm compatibility with existing power factor correction controllers

For optimal performance and longevity, ensure the contactor is installed in a well-ventilated enclosure to prevent excessive heat buildup. Regularly inspect the main terminals for tightness and check the auxiliary contact functionality during routine maintenance intervals.
