ALI Isolating Switch for Electrical Distribution

The ALI Isolating Switch ensures safe power disconnection in industrial settings. Compliant with EN/IEC 60947-3, it supports 1–4 poles, rated currents from 16A to 125A, and voltages up to 400V AC. Suitable for AC-22A loads, it offers high short-time and impulse withstand capacity. With 10,000 mechanical operations, compact DIN rail mounting, and IP20 protection, it is ideal for secure isolation in control panels, motor circuits, and machinery.

    Product Details

    Product Descriprion

    ALl-125-2

    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.
