FAQs
Install the device with three main NO contacts wired in series with the motor circuit and connect the coil terminals to the 110 V control supply (50/60 Hz). Tighten main terminals to 4 N·m and coil terminals to 1 N·m as specified, using screw terminals. Maintain proper clearance and ensure IP20 protection on the coil side to prevent dust ingress. Use the optional auxiliary contact blocks if the control logic requires feedback or interlocking. This setup minimizes startup transients and ensures reliable interlock behavior in automated lines.
Yes, it is designed for 690 V AC main circuits. The rated operational current for AC-3 is 43–65 A depending on voltage and temperature; for AC-1 operations it is 80–115 A depending on voltage and ambient temperature. This provides ample headroom for moderate to heavy motor loads, enabling reliable starting and switching without overheating under typical industrial duty cycles.
The device features CE conformity for European markets and CB certification for global electrical safety compliance. It is RoHS compliant with REACH declarations and supports CCC, CQC, SSD UL-related references for broader regulatory acceptance. This combination helps ensure that panel builders meet stringent regulatory requirements while simplifying cross-border procurement.
The block contactor has a compact footprint of 70 mm width, 110 mm depth, and 108 mm height, with screw terminals for all main and control connections. Coil terminals are rated IP20, and main terminals IP10, aiding safe operation inside control cabinets. Use the external accessory range to extend functionality, and ensure mounting spacing complies with standard enclosure layouts to facilitate servicing and future expansion.
The device delivers robust motor control with low power loss—6.5 W per pole for AC-1 and 1.5 W per pole for AC-3—reducing heat in the control panel and prolonging relay life. Its 3-pole 690 V capability and 110 V control voltage minimize downtime due to mis-wiring and mismatched components. Combined with CE/CB compliance and optional auxiliary blocks for expanded control logic, the contactor supports higher uptime and lower maintenance costs over the system lifecycle.
