FAQs
To install the 1SBL281074R8810, verify coil voltage matches your control supply (230-240 V at 50 Hz or 240-260 V at 60 Hz) and connect the 3 main NO contacts plus the 1 NO auxiliary contact. Use screw terminals for secure wiring and ensure IP20-rated enclosure protection. Mounting should follow manufacturer guidelines to maintain thermal performance.
At 690 V operation, the contactor supports up to 55 A in AC-1 service and 32 A in AC-3 service, depending on ambient temperature and coil voltage. It is designed for 690 V insulation, with protective class IP20 and a rated short-time withstand and switching frequency suitable for moderate-duty motor control.
Yes. With 3 NO main contacts and 1 NO auxiliary contact, and an AC-3 rating of up to 32 A at higher voltages, the device is well suited for starting and stopping three-phase motors in packaging lines. The compact form factor simplifies control cabinet design and helps reduce wiring complexity.
The AX32/AX40 family includes CE conformity with declarations of conformity, UL/CSA certification for relevant models, and RoHS compliance. Additional certifications such as CCC, CQC, and RoHS updates ensure robust worldwide acceptance and regulatory alignment for complex supply chains.
The device fits within a compact footprint: 54 mm net width, 90 mm net depth, and 108.3 mm net height, with a product net weight of 0.667 kg. These dimensions simplify enclosure planning, enable denser panel layouts, and reduce overall equipment footprint in modern switchgear.
