The CJ19(16) Series capacitor contactors are designed for seamless switching of low voltage shunt capacitors in 380V 50Hz reactive power compensation systems. They feature an integrated inrush current suppression mechanism to minimize capacitor stress during activation, offering compact size, strong switching capability and simplified installation. Configurations from 25A to 95A are available.

CJ19(16) capacitor contactors are key components in modern power infrastructure, specifically designed to manage low voltage shunt capacitors in reactive power compensation installations. The primary role is to optimize energy efficiency by dynamically adjusting power factor correction in industrial, commercial and utility-scale systems. Compatible with 380V 50Hz networks, they ensure stable performance in a variety of environments, from manufacturing plants to renewable energy grids, where accurate capacitor switching directly affects operational reliability and energy cost savings.

The CJ19(16) capacitor contactor has a built-in surge current suppression mechanism. Conventional capacitor switching often generates harmful surge currents during activation, shortening the life of the capacitor and destabilizing the power system. The CJ19(16) series capacitor contactor reduces this risk by integrating a specialized damping circuit that gradually increases the current, reducing the peak surge by more than 70%. This innovation not only extends the durability of the capacitor, but also minimizes electromagnetic interference, ensuring compliance with strict industrial safety standards.

The CJ19(16) capacitor contactor delivers high performance in a compact, lightweight package. Designed for space-constrained installations, its streamlined form factor easily integrates into existing control panels or modular compensation cabinets. Silver alloy contacts and arc extinguishing chambers provide excellent switching durability, supporting over 1 million mechanical operations under frequent switching conditions. Durability combined with tool-free terminal connections speeds up maintenance workflows and reduces downtime in high-demand environments.

To meet different operating needs, the CJ19(16) Series capacitor contactors are available in six current ratings: 25A, 32A, 43A, 63A, 85A and 95A. Scalability allows for seamless integration with capacitor banks of varying sizes, from small commercial settings to heavy industrial applications. Each model is rigorously tested to ensure stable performance under temperature fluctuations (-25°C to 60°C) and humidity levels up to 95%. The standardized mounting design further enhances compatibility with third-party compensation controllers, providing system integrators with plug-and-play convenience.

The CJ19(16) capacitor contactor’s low-power coil design reduces energy consumption in standby mode, and the lead-free material complies with global RoHS directives. By enabling efficient reactive power compensation, it can indirectly reduce carbon footprint by reducing grid transmission losses. Designed as a forward-thinking solution for industries balancing operational efficiency and sustainability goals, the CJ19(16) series capacitor contactors solidify their position as a future-proof investment in the smart grid ecosystem.
