FAQs
The 1SBL371074R3600 is part of ABB’s AX50–AX80 block contactor family and is designed for 3-phase motor control up to 690 V. It supports add-on auxiliary contact blocks for side mounting and a range of ABB accessories, enabling seamless integration with existing ABB relays and control panels.
This model provides 3 NO main contacts (NO = normally open) and 0 NC contacts, with main circuit rated up to 690 V and a conventional free-air thermal current Ith of 125 A. It supports AC-1 and AC-3 operation with voltages suitable for 415–690 V ranges and appropriate current ratings per voltage class.
The coil is rated for 50 Hz at 190 V and 60 Hz at 220 V. Wiring should follow the coil terminals with proper torque (1 N·m) and ensure coil polarity is observed if applicable. This enables proper energization and reliable operate/release timing across regional power standards.
The AX50–AX80 family, including this model, carries CE and UL certifications, with RoHS compliance and supporting declarations (CCC, CQC where applicable). This combination supports global conformity, safe electrical operation, and regulatory alignment for international projects.
Use screw terminals with 4 N·m main torque and 1 N·m control torque to ensure lasting connections in vibration-prone environments. Opt for add-on auxiliary contact blocks to extend control capabilities without replacing the base device. The compact footprint reduces panel space, while low coil power loss (6.5 W AC-1, 1.5 W AC-3) minimizes heat and energy costs over time.
