Working Principle of CJ19 - 95 Contactor
1. Electromagnetic activation system
The contactor uses an electromagnetic coil powered by a 380V AC power supply to generate a magnetic field to drive the armature movement. When the coil is energized, the armature closes the silver alloy contacts, allowing current to flow through the three-phase circuit. This mechanism ensures fast and accurate switching of capacitive loads (such as power capacitors) in applications such as reactive power compensation and harmonic suppression.
2. Arc extinguishing and contact protection
The contactor is equipped with a ceramic arc chute and high-quality silver contacts to minimize arcing during circuit breaking. The arc chute effectively dissipates heat and extinguishes the arc, thereby reducing erosion and extending the electrical life of the contacts. This design complies with advanced intelligent circuit protection principles to ensure safe switching of high-current capacitive loads such as capacitor banks. 14
3. Capacitor switching and power factor optimization
The contactor is designed for capacitor switching applications to manage the connection and disconnection of power capacitors in three-phase AC systems. By controlling the capacitor bank, it dynamically compensates for reactive power, improves power factor (>0.99) and reduces harmonic distortion (<5%) in accordance with IEC 61000-3-2 standard 25. This process improves energy efficiency and stabilizes grid performance.
4. Three-phase load balancing
Three-phase contactors ensure balanced current distribution across all phases, solving the three-phase imbalance problem common in industrial power grids. Their low-resistance contacts and optimized magnetic circuit design minimize voltage drop and heat loss, supporting stable operation of systems that require uninterruptible power switching14.
5. Integrated intelligent control
Advanced models are equipped with real-time monitoring sensors and microprocessor-based control modules. These components detect parameters such as coil voltage, contact temperature and load current, enabling automatic fault diagnosis and overload protection. The contactors can be connected to smart grid systems via Modbus/RS485 communications for remote control and predictive maintenance15.
6. Environmental adaptability
Designed for harsh industrial environments, the contactor's IP65-rated housing is dust, moisture and chemical resistant. Its H-class insulation (up to 180°C) and corrosion-resistant components ensure reliable performance in applications such as substations, data centers and renewable energy systems.

It is the details that demonstrate the quality
Silver alloy contacts: excellent conductivity and arc resistance
BY CJ19-95 series AC contactors feature silver alloy contacts, ensuring superior conductivity and long-term durability in demanding applications. Silver alloys, such as silver tungsten (AgW), are known for their low contact resistance and resistance to arc erosion, which is critical in capacitor switching scenarios where surge currents frequently occur. These contacts minimize energy losses during operation and maintain stable performance even under repetitive switching cycles, such as in reactive power compensation systems or harmonic mitigation solutions.In capacitor switching applications, silver alloy contacts effectively suppress arcing during circuit interruption, a common challenge when disconnecting large capacitors (e.g. 22kvar systems). This reduces contact wear and extends the electrical life of the contactor by up to 30% compared to traditional copper-cadmium alloys, as verified by the IEC 60947-4-1 standard. In addition, the alloy’s high thermal conductivity ensures rapid heat dissipation, preventing overheating in environments with ambient temperatures up to 40°C, such as industrial switchboards or solar farm control cabinets.
Slider design: simplified installation, modular flexibility
The BY CJ19-95 series’ slide-on design allows for seamless 35mm DIN rail mounting, which is essential for modern modular electrical systems. This design eliminates the need for complex screw-on processes, allowing technicians to install the contactor into a control panel in seconds. The slide-on mechanism is compatible with both vertical and horizontal mounting orientations, making it suitable for space-constrained environments such as commercial building distribution boxes or renewable energy inverters.For industrial applications that require frequent maintenance, the slider’s tool-free removal feature simplifies component replacement. The design also incorporates anti-vibration reinforcement to ensure stable operation in high-vibration environments such as manufacturing plants or wind turbine control systems. In addition, the slider’s insulated terminal covers prevent accidental contact with live parts, improving safety and meeting UL and CE safety certifications for commercial and industrial installations.
High-performance copper coils: energy efficiency and reliability
The BY CJ19-95 series uses copper coils designed for optimal electromagnetic performance and energy efficiency. The low resistivity of copper ensures minimal power loss during coil excitation, reducing operating costs in systems that require continuous capacitor switching, such as three-phase power correction or voltage stabilization networks. The coils are rated for a voltage range of 0.85–1.1Un and maintain reliable operation even in the presence of grid fluctuations, preventing burnout in low voltage situations .In renewable energy applications, the copper coil’s moisture resistance (up to 90% RH) and wide temperature range (-5°C to 40°C) ensures consistent performance in harsh outdoor environments such as solar farms or offshore wind installations. The coil’s design also incorporates noise suppression technology, which reduces audible hum by 50% compared to aluminum coils, which is critical for commercial buildings where noise control is important.
