FAQs
The 1SBL371074R8500 uses a block-contactor design with side-mount add-on auxiliary contact blocks. Align the auxiliary block with the main body, secure with the provided fittings, and wire per the terminal design (control circuit terminals for the coil, main circuit terminals for the motor). Ensure correct torque on all connections (Main Circuit 4 N·m, Control Circuit 1 N·m) and verify coil voltage (380–400 V at 50 Hz or 400–415 V at 60 Hz) before energizing.
At 55 °C, AC-1 rated current is 115 A at 690 V and 95 A at 220/240 V; AC-3 rated current is 65 A at 415–690 V and 65 A at 380/400 V. This enables reliable switching for motor-start and running conditions across a wide voltage range, aligning with IEC 60947-4-1 expectations.
Yes. With three main NO contacts, 3-pole block design, and AC-3 power switching up to 65 A at high voltages, it is well-suited for conveyor motors and similar load profiles. The device also supports accessories for tailored control circuit configurations, aiding in robust panel integration and serviceability.
The product carries CE and UL certifications. It also lists CCC, CQC, and CB documentation, along with DoC for CE. These attest to compliance with global electrical safety, installation, and environmental requirements for control gear.
Regular checks should focus on torque adherence (Main 4 N·m, Control 1 N·m), inspection of coil resistance and insulation integrity, and wear monitoring on contact surfaces. The compact form factor, high Icw, and scalable accessories reduce downtime and spare-part complexity, contributing to lower maintenance costs and improved uptime in continuous-production environments.
