FAQs
The 1SBL281074R8601 is designed to fit within the AX32-40A family’s accessory ecosystem, offering a 3-pole main contact arrangement with a built-in NC auxiliary contact. It supports similar coil voltages and control circuit interfaces, enabling straightforward substitution or expansion in existing installations. When upgrading, verify coil voltage (50 Hz 400–415 V or 60 Hz 415–440 V) and ensure panel clearance meets the 54 mm width. Use the same spindle torque for main terminals (2.3 N·m) and compliant auxiliary torque (1 N·m) to maintain reliability.
For AC-3 operation at 690 V, the device provides a rated operational current of 21–32 A depending on voltage and temperature; specifically 32 A at 415–440 V in 55 °C scenarios. For AC-1, the rated current is higher at lower switching voltages, with typical values around 55 A at 220/240 V and similar figures for other low-voltage configurations. Short-time withstand (Icw) includes 400 A for 10 seconds and 65 A for 15 minutes, ensuring short-term fault endurance during motor starting.
Yes, the device supports 690 V main circuit operation with a rated insulation voltage of 690 V and 6 kV impulse withstand on the auxiliary circuit, providing protection against surges in industrial settings. It also features IP20 protection on terminals, and ROHS/REACH compliance, which helps with regulatory requirements in many sectors. Its mechanical switching frequency and robust thermal performance further ensure reliable operation in moderate to challenging environments.
The product carries CE for European conformity, UL certification for North American safety compliance, and CCC certification for China, along with CQC and CCC DoC documentation. These certifications simplify supplier qualification, reduce third-party testing needs, and support audits across global manufacturing sites. RoHS and WEEE declarations also aid in environmental compliance, making this contactor suitable for multi-region deployments with stringent regulatory expectations.
The 1SBL281074R8601 offers a compact footprint, integrated auxiliary contact, and low per-pole power loss (2.5 W AC-1, 0.9 W AC-3), which collectively reduce energy waste and heat in the control circuit. Its long mechanical life (up to 3600 cycles per hour) and rated fault tolerance minimize downtime and maintenance costs. Compatibility with standard ABB accessories enables scalable automation, supporting faster upgrades and a lower total cost of ownership in modern control panels.
