FAQs
The 1SBL281074R8110 uses a block contactor design compatible with add-on auxiliary contact blocks for front or side mounting. Its 54 mm width and 90 mm depth fit standard control panels, while the 108.3 mm height keeps wiring clear. Pairing with AX accessories enables scalable logic, signaling, and interlocking without changing the core mounting footprint.
At 690 V and 55 °C, the rated operational current AC-3 is 21 A, with higher current ratings at lower voltages (e.g., 32 A at 415 V). The device provides 690 V insulation, 50/60 Hz operation, and a maximum breaking capacity suitable for typical 3-phase motor drives up to about 18.5 kW depending on voltage.
This ABB contactor carries CE and UL certifications, with related declarations and certificates (CCC, CQC) documented. RoHS and REACH compliance are noted, helping meet global regulatory requirements. These certifications support safe installation in diverse markets and provide audit-ready assurance for procurement and maintenance teams.
Maximum mechanical switching frequency is 3600 cycles per hour, while electrical switching supports up to 1200 cycles per hour (AC-3). This makes the 1SBL281074R8110 suitable for high-cycle manufacturing lines and continuous-operation applications, with predictable wear patterns enabling proactive maintenance programs.
Wire using screw terminals with IP20 protection on coil and main terminals. The unit’s dimensions (54 mm wide, 90 mm deep, 108.3 mm high) support compact panel layouts, and tightening torques are specified for auxiliary, control, and main circuits. Use add-on accessory blocks to tailor signaling and interlocking to your control scheme.
