FAQs
Yes. The 1SBL351074R8811 is designed for three-phase motor control up to 690 V AC, supporting AC‑1 and AC‑3 loads. Its screw terminals and IP20 coil terminals simplify panel mounting, while the compact footprint fits tight control cabinets common in manufacturing lines.
The coil accepts 230–240 V at 50 Hz and 240–260 V at 60 Hz, ensuring compatibility with standard European and international mains. This reduces the need for transformer variants and supports consistent performance across typical 50/60 Hz environments.
The block contactor carries CE and UL certifications, plus RoHS compliance and CB/CCC declarations. These certifications verify electrical safety, electromagnetic compatibility, and material compliance, simplifying global product approvals and customer acceptance in regulated industries.
The device uses screw terminals for secure wiring and supports add-on auxiliary contact blocks for side mounting, enabling flexible control schemes. Its compact 82 × 110 × 108 mm envelope fits compact panels, while the 1.05 kg weight eases handling during installation and retrofits.
With low coil power loss (5 W AC‑1 per pole, 1.3 W AC‑3 per pole), high short‑time withstand ratings, and robust mechanical life, maintenance intervals lengthen and energy waste declines. The modular design and accessories reduce downtime during replacements and allow scalable control architectures.
