Business impact: Safe, PLC-friendly coil drive that lowers control wiring costs and improves integration with standard automation systems. Application: Ideal for automation panels in process and packaging lines requiring low-voltage control without sacrificing performance. Feature: Rated operational current AC-3 up to 35–50 A and AC-1 up to 85–100 A depending on voltage. Business impact: Supports medium-power motors with clear duty-cycle specs, reducing oversizing and providing predictable performance. Application: Direct-medial motor control for fans, pumps, and small conveyors in machine rooms. Feature: Low power loss per pole (AC-1 5 W, AC-3 1.3 W). Business impact: Improves energy efficiency, lowers heat in enclosures, and extends device life in continuous operation. Application: Continuous-duty motor control in packaging lines and process automation. Feature: IP20 coil terminals and IP10 main terminals with screw connections and defined tightening torques. Business impact: Safer and easier field installation, plus reliable torque maintenance reduces connection looseness. Application: Field-installed control panels where high reliability and straightforward maintenance are required. Feature: Compact dimensions (70 mm W x 110 mm D x 108 mm H) and weight (1.01 kg).

FAQs
Install the 3-pole block contactor with its main terminals using screw connections rated IP10 for the main circuit and IP20 for the coil terminals. Use the recommended tightening torques (Main 4 N·m, Control 1 N·m) to ensure secure connections. If needed, add-on auxiliary contact blocks can be mounted on the side; verify 48 V coil operation (50/60 Hz) and confirm 690 V insulation for safe operation.
At 220/240 V, Ie is 85 A for AC-1; at 690 V, Ie is 100 A for AC-1, with 70 A at 690 V and 70 °C. For AC-3, ratings include 50 A at 415 V, 45 A at 440–500 V, and 35 A at 690 V (55 °C). These figures enable precise motor-control sizing for pumps, fans, and conveyors.
Yes. The 3NO main contacts support typical motor-start/stop sequences in pumps and conveyors, with AC-3 ratings appropriate for starting and running induction motors. The compact footprint and 48 V control coil simplify integration with PLCs, while the 690 V insulation supports robust operation in diverse process environments.
The unit ships with UL and CE certifications and RoHS compliance. It also has a Declaration of Conformity and CB/CCC references in the certificate suite, ensuring global electrical-standard alignment and traceability for regulated markets.
The contactor delivers low coil fade with power losses of 5 W per pole in AC-1 and 1.3 W per pole in AC-3, reducing heat and energy consumption in continuous operation. This translates to longer component life, lower enclosure cooling needs, and favorable total cost of ownership in automated lines.
