FAQs
This block contactor uses screw terminals and supports a control circuit voltage of 50 Hz 380–400 V or 60 Hz 400–415 V. It is designed for three main NO contacts and a single NO/NC auxiliary contact, enabling straightforward wiring in standard control panels. Optional add-on auxiliary blocks allow side mounting, simplifying integration with existing S1 bus bars and DIN rail assemblies.
AC-1 ratings deliver 95–115 A at 220/240 V or 40 °C ratings up to 115 A at 690 V, while AC-3 ratings reach 65 A at 415–690 V and up to 65 A at 380/400 V. Rated power for AC-3 is 30–37 kW depending on voltage, with short-time withstand currents up to 650–1000 A and a maximum breaking capacity around 630–1300 A depending on voltage and power factor.
Yes, within its specified ambient range. The unit supports ambient temperatures from -40 to 70 °C in general operation, with the option for installation near equipment. It features IP20 coil terminals and IP10 main terminals, which contributes to rugged indoor performance. For extreme outdoor exposure, ensure enclosure protection and consider derating against altitude (3000 m max without derating).
The device is CE and UL certified, with CCC and CQC certificates listed. It also carries a CCC Declaration of Conformity, CE Declaration of Conformity for 3-pole contactors, and RoHS/REACH declarations. WEEE categorization is Business To Business, highlighting compliance in industrial settings and facilitating regulatory approval for European and Asian markets.
The design emphasizes low per-pole power loss (6.5 W AC-1, 1.5 W AC-3) which reduces heat, lowers cooling needs, and improves energy efficiency. With a robust mechanical life and modular accessories, maintenance intervals can be extended, downtime minimized, and spare-parts stock rationalized, delivering a favorable total cost of ownership in continuous-duty motor control applications.
