Feature → Business Impact → Application: AF52B-30-11-14 uses AF technology to tolerate wide control voltage variations (250–500 V) with DC support, reducing panel energy consumption and preventing misoperation in fluctuating networks. This translates to fewer trips and improved uptime in motor control applications up to 30 kW at higher voltages, making it ideal for conveyors, pumps, and fans. Feature → Business Impact → Application: Built-in surge protection and a compact block design minimize external protection components and panel footprint, lowering installation time and wiring complexity in compact control cabinets. Feature → Business Impact → Application: The 3P main contacts with 1 NO and 1 NC auxiliary pair enable direct signaling and circuit monitoring, while add-on auxiliary blocks allow scalable control without reworking cabinets. Feature → Business Impact → Application: DIN rail mounting TH35-15/TH35-7.5 and screw-fit options simplify retrofits and new builds, ensuring quick, secure installation in standard panels. Feature → Business Impact → Application: Wide certification coverage (IEC/EN 60947-1, IEC/EN 60947-4-1, UL/CSA references) reduces compliance risk in global deployments, supporting CE/UKCA declarations and cross-border sourcing. Feature → Business Impact → Application: Coils with low consumption (4 V·A holding at 50/60 Hz; 2 W DC) reduce heat and power draw in control circuits, improving overall energy efficiency and reliability in energy-conscious facilities.

FAQs
The AF52B-30-11-14 supports DIN rail mounting on TH35-15 or TH35-7.5 rails and can be mounted with two M4 or M6 screws diagonally if preferred. Main circuit terminals are screw-type with 50/60 Hz control and 690 V main ratings, while auxiliary terminals use IP20 protection. Flexible ferrule or rigid conductor connections are supported for 4–35 mm² main conductors and 0.75–2.5 mm² auxiliary conductors.
The device features 3 main NO contacts and 1 auxiliary NO plus 1 auxiliary NC contact. Rated operational current for AC-3 is up to 53 A at 415–690 V, with AC-1 up to 100 A at 690 V. Coil voltage tolerance is 250–500 V for AC and DC operation, and the unit includes built-in surge protection for robust switching of motor loads.
Yes. It is designed for AC-3 and AC-1 operations up to 690 V, with ratings such as 30 kW at various voltages, and a wide control voltage tolerance that helps manage network fluctuations. It is suitable for pumps, fans, conveyors, and other motor-driven equipment in harsh or unstable electrical environments.
The AF52B-30-11-14 complies with IEC/EN 60947-1 and 60947-4-1, UL 60335-2-40 family, and CSA equivalents, with CE and UKCA declarations available. These certifications support global deployments and supplier qualification, reducing regulatory risk in multinational projects.
AF technology provides a wide control voltage range and built-in surge protection, reducing panel components and energy waste. The coil consumption is low (4 V·A at 50/60 Hz or 2 W DC), which lowers heat in enclosures and extends service life. The modular design also simplifies maintenance and future expansions, delivering lower total cost of ownership.
