AF technology delivers a wide control voltage range of 250 to 500 V across AC and DC, with built-in surge protection. This means fewer voltage problems in unstable networks, reducing nuisance trips and energy waste in lighting and drive applications. The 8-pole NO configuration consolidates control circuits, minimizing panel size and simplifying wiring while delivering up to 45 A AC-1 operation at 690 V. The DIN-rail mounting compatibility (TH35-15 or TH35-7.5) and screw-terminal connections streamline installation, improve reliability, and ease field servicing in maintenance cycles. With low coil power loss—1.6 W per pole for AC-1 and 0.42 W per pole for AC-3—the solution lowers heat generation and operating costs in continuous duty scenarios. The block contactor design supports add-on auxiliary contact blocks for scalable control and fault-tolerant configurations, while IP20 protection and rated insulation enable safe integration in standard industrial enclosures. Compliance and certifications, including IEC/EN 60947-1, IEC/EN 60947-4-1, UL 60335-2-40 LZGH2 A2L, CE and UKCA, deliver regulatory confidence for global projects. Field compatibility with a wide range of conductor sizes and mounting accessories ensures robust connections in diverse installations.

Install on TH35-15 or TH35-7.5 DIN rails and secure using the two M4 screws supplied with the panel hardware. Terminate the main circuit with 1/2x 16 mm² to 4 mm² conductors and the control circuit with 0.75 to 2.5 mm² conductors as per the connecting capacities. Ensure coil voltage is within 250–500 V, and tighten terminals to the recommended torque values for reliable operation.
Main circuit rated voltage is 690 V with rated operating currents up to 45 A at 40–70 °C for AC-1, and 10.5–23.2 A for AC-3 depending on voltage. Control circuit voltage is 250–500 V for 50/60 Hz operation, with coil power losses of 1.6 W per pole (AC-1) and 0.42 W per pole (AC-3). Impulse withstand is 6 kV, and insulation voltage is 690 V.
Yes, it is designed for UL lighting scenarios. It carries UL/CSA approvals including UL 60335-2-40 LZGH2, and CE/UKCA declarations for international use. The device also conforms to IEC/EN 60947-1 and 60947-4-1 standards, ensuring compliance in standard industrial electrical panels and lighting control circuits.
AF technology provides a wide control voltage range (250–500 V) and built-in surge protection, enabling stable operation despite voltage fluctuations. This reduces misoperation and panel trips, improves energy efficiency by minimizing wasted power due to voltage spikes, and supports consistent motor starting and lighting control in networks with unstable supply conditions.
The 8-pole design reduces component count and wiring complexity, lowering installation and maintenance time. Low coil power loss reduces heat and ongoing energy costs, while modular add-on blocks simplify upgrades and fault isolation. With robust IP20 protection and DIN-rail mounting, uptime improves and total cost of ownership drops in continuous-duty lighting and motor-control applications.
