ALI Isolating Switch for Electrical Distribution
Product Details
Product Descriprion
The ALI Isolating Switch provides reliable power disconnection for industrial applications. Certified to EN/IEC 60947-3 and carrying CE and ISO9001 approvals, it features 1-4 pole configurations (16A-125A rating) with enhanced current capacity. Engineered for safety, it withstands 12x In short-circuit current and 4000V impulse voltage. The red operation lever ensures clear on/off status visibility, while IP20 protection shields internal components.
Optimized for demanding environments, this switch delivers 10000 mechanical operations and 1500 electrical endurance cycles. Compatible with cables up to 50mm² (pin/lug terminals), its 17.5mm-per-pole slim profile facilitates high-density DIN rail mounting in control panels, HVAC systems, and machinery cabinets. Critical specs include 690V insulation voltage, 4000V impulse withstand, and UL-certified wiring configurations – making it ideal for secure maintenance isolation in industrial power distribution.
