Low Voltage Contactor

Within low-voltage automated control systems, the Low Voltage Contactor acts as a key component enabling weak current to control strong current, mainly applied to low-voltage power distribution and control circuits with rated voltages below 1000V, especially automation scenarios with low-voltage coil power supply such as 24V and 48V. Our manufactured Low Voltage Contactor covers mainstream current ratings from 6A to 100A, with coils supporting multiple low-voltage specifications including DC 24V and AC 24V. It can directly connect with industrial control systems such as PLC and DCS without additional booster devices, greatly simplifying cabinet design and wiring. In intelligent manufacturing production lines, building automation systems and small automated equipment, this Low Voltage Contactor has become the preferred solution for low-voltage control circuits due to stable low-voltage pull-in performance and ultra-low operating power consumption.

This Low Voltage Contactor adopts an energy-saving magnetic circuit system; its low-voltage coil pull-in power consumption is only half that of traditional products, eliminating coil overheating even under long-term continuous operation, making it particularly suitable for automation systems requiring uninterrupted 24-hour operation. Main contacts adopt a double-break bridge structure with fast breaking speed and strong arc extinguishing capacity, reliably cutting load current under low-voltage high-current working conditions. The overall compact design reduces volume to only 70% of ordinary contactors with equivalent current ratings, effectively saving internal installation space within control cabinets. Meanwhile, various functional accessories can be rapidly installed without tools, including auxiliary contacts, mechanical interlocks and surge suppression modules, greatly improving on-site commissioning and maintenance efficiency.

Application Fields

 

Low Voltage Contactors are widely deployed across various low-voltage automatic control scenarios. In intelligent manufacturing, they serve as core switching elements for low-voltage control circuits of industrial robots, automated production lines and intelligent warehousing equipment, driven directly by PLC output signals to realize precise equipment start-stop control. For building automation systems, they are extensively used in low-voltage control of central air conditioning terminals, lighting circuits, elevator door machines and other equipment, cooperating with building management systems to implement intelligent energy consumption management. In the new energy sector, they are indispensable for low-voltage branch switching of photovoltaic combiner boxes and energy storage systems. Furthermore, they are commonly selected as basic control components for medical equipment, packaging machinery, food processing equipment and other scenarios with high requirements for control precision and safety.

 

Customization Capability

 

 

We support full-dimensional customized services for Low Voltage Contactors to satisfy differentiated demands of customers across various industries. Customers may provide technical drawings or functional requirements, and our R&D team will rapidly conduct assessments to output customized solutions covering special coil voltages, non-standard contact configurations, customized housing logos, dedicated accessory integration and more. The development cycle for customized products typically ranges from 15 to 90 working days, adjusted flexibly according to product complexity. Custom samples can be provided for customer testing and verification prior to mass production, with sample fees fully refunded upon subsequent formal order placement. The minimum order quantity for customized orders is 10 pieces, and models with different configurations can be mixed within a single order to fully meet diversified procurement demands.

We have established a full-process quality control system to ensure every Low Voltage Contactor delivers stable and reliable quality. Starting with raw material incoming inspection, rigorous sampling tests are performed on core materials including copper, plastic and contact alloys; materials failing standards are never put into production. Exclusive inspection stations are arranged for key processes such as stamping, coil winding and assembly to conduct batch-by-batch checks on part dimensions, coil resistance and assembly precision. All finished products undergo 100% full inspection before warehousing, covering switching performance tests, insulation withstand voltage tests, low-voltage pull-in reliability tests, temperature rise tests and multiple other inspection items; non-conforming products are directly reworked or scrapped. We allow customers to commission third-party institutions to conduct pre-shipment factory inspections and fully cooperate with inspection procedures to guarantee delivered products fully comply with customer quality requirements.

We offer flexible payment schemes to facilitate smooth cooperation. For standard Low Voltage Contactor orders, the conventional payment process applies: 30% advance deposit, with the remaining 70% balance settled before shipment. For customized product orders, settlement terms are 50% advance deposit and 50% balance paid prior to delivery. We support settlement in multiple international currencies including US Dollars and Euros, and can provide corresponding documents matching customers' financial procedures. Tiered price discounts are available for bulk long-term purchasers, with greater discount intensity corresponding to larger order volumes; specific discounts can be negotiated bilaterally based on actual order quantities to fully safeguard profit margins for partners.
