Feature → Business Impact → Application: 3 main NO contacts with 1 NO and 1 NC auxiliary contact block reduce the number of devices in a control cabinet and streamline wiring, saving space and labor during installation in conveyors and pumps. Feature → Lower power loss: 5 W per pole for AC‑1 operation and 1.3 W per pole for AC‑3 operation translate into cooler operation and improved energy efficiency, especially in high-cycle applications like fans and conveyors. Feature → 690 V rated insulation and 6 kV impulse withstand provide robust protection against voltage spikes in demanding industrial environments, enabling safer integration with higher‑voltage motor drives. Feature → Screw terminals with IP20 protection and a tightening torque of 4 N·m main circuit offer dependable, vibration‑resilient connections suitable for rugged factory floors. Feature → 3P2C auxiliary arrangement (1 NO / 1 NC) supports interlock and signaling needs, simplifying control logic and fault diagnosis. Feature → Compact dimensions (82 mm W × 110 mm D × 108 mm H) and 1.05 kg weight facilitate denser panel layouts and easier installation on machine frames. Feature → Wide compatibility with side-mounted auxiliary blocks and CAD data (2D/3D) accelerates engineering workflows and spare part planning. Feature → UL/CSA and CE DoCs, REACH and RoHS compliance reduce regulatory questions during audits and customer acceptance testing. Application: Suitable for motor starters in material handling, packaging lines, pumps, and general industry motor control where 3‑pole, 690 V AC operation is required.

FAQs
Yes. The 1SBL351074R7511 is a 3‑pole block contactor designed for side-mount auxiliary contact blocks. Its screw-terminal terminals and IP20 protection support straightforward panel mounting and future expansion. When configuring, verify the auxiliary contact arrangement (1 NO / 1 NC) and ensure accessory mounts align with your enclosure or busbar system for clean wiring and reliable operation.
AC-3 Ie varies with voltage: at 220/230/240 V, about 53 A; at 380/400 V, 50 A; at 415 V, 55 °C, 50 A; at 440 V, 55 °C, 45 A; at 500 V, 55 °C, 45 A; at 690 V, 55 °C, 35 A. These figures reflect thermal limits under standard ambient conditions and help you match motor startup loads to the contactor, ensuring reliable starting performance.
Yes. The device is rated for main and auxiliary circuits up to 690 V AC with a Ui of 690 V and 6 kV impulse withstand. It supports motors up to high voltage drive environments and is compatible with typical motor starting and stopping sequences in conveyors, pumps, and similar machinery. Ensure proper sizing for Ie, Pe, and short-time ratings (Icw) to meet your duty cycle.
This ABB block contactor aligns with CE and UL/CSA requirements, and carries RoHS and REACH declarations. It also references CCC, CQC certifications and DoCs as part of the broader AX50–AX80 family, supporting global product approvals. These certifications simplify regulatory approvals, audits, and customer acceptance for international projects.
Low power loss (5 W per pole AC-1, 1.3 W per pole AC-3) reduces heat in the control cabinet, improving reliability and extending component life. The modular design with add-on auxiliary contacts and CAD data accelerates commissioning and spare parts planning. Together, these factors lower maintenance costs and shorten downtime during motor startup and fault resolution.
