Socomec SIRCO VM 160A Load-Break Isolating Switch

The Socomec SIRCO VM 160A Load-Break Isolating Switch (model 21004160) is a compact, IEC 60947-3 compliant modular load-break switch designed for safe isolation and load switching in LV distribution panels, motor control centres, and service entrance panels across Saudi Arabia's industrial and commercial sectors. As a dedicated load-break isolator — rather than a circuit breaker or fuse combination — the SIRCO VM provides the clear-visible-gap isolation function required by IEC and Saudi building codes for main panel isolators, generator changeover switch applications without automatic control, and capacitor bank isolation. The SIRCO VM's design philosophy centres on three principles: visible isolation confirmation (the switch blade position is directly observable through the transparent cover), reliable operation under the shock and vibration conditions of industrial panels, and a compact footprint that minimises the busbar space occupied in an LV switchboard.

At 160A, the SIRCO VM covers the isolator requirement for distribution circuits commonly found in Saudi commercial and industrial buildings: the incoming isolation for an LV distribution board feeding a floor of a commercial building (typically 63–160A), the motor feeder isolation for medium-sized motors in the 15–55 kW range on 400 V supply, the generator manual transfer switch for small backup generator installations where manual changeover is acceptable, and the main isolation for capacitor power factor correction banks. The SIRCO VM 21004160 is available in 3-pole and 4-pole versions; the 4-pole version is the standard selection for applications where neutral switching is required, consistent with SEC grid code practice in Saudi Arabia for TN-C-S earthing systems.

In Socomec's product ecology, the SIRCO VM is frequently used in combination with ATYS automatic transfer switches in generator backup systems: the SIRCO VM provides the manual bypass isolation capability that allows the ATYS ATS to be safely removed for service without interrupting the manual generator supply. This bypass arrangement is a standard design requirement in ARAMCO and Ministry of Health electrical specifications for critical backup power systems, where the ability to maintain supply continuity during ATS maintenance is a fundamental reliability requirement. Saudi National Guard hospitals, King Faisal Specialist Hospital and Research Centre, and numerous private hospitals across the Kingdom use SIRCO VM switches in this ATS bypass role.

Razz Middle East stocks SIRCO VM switches across the full current range from 16A to 630A, with 3-pole and 4-pole options. The compact DIN-rail compatible design ships ready for immediate panel installation. We provide technical selection support to ensure the correct breaking capacity, utilisation category (AC21A or AC22A), and pole count for each application.
