LS Electric UTS Isolator Switch

The LS Electric UTS Isolator Switch is a heavy-duty load-break isolating switch designed for safe isolation and de-energisation of electrical circuits and equipment in industrial and commercial installations across Saudi Arabia. Available in 3-pole and 4-pole configurations from 32 A to 1600 A, the UTS provides a clearly visible open/closed indication and a robust mechanical interlock that prevents the panel door from being opened while the switch is in the closed (energised) position — meeting the ATEX, IEC 60947-3, and Saudi OSHA lockout/tagout requirements for isolation of hazardous energy. The UTS is designed for installation as a main incomer switch for distribution boards, as a motor isolator for safe maintenance access, and as a generator or solar PV source isolator in Saudi Arabia's rapidly growing solar energy sector.

The UTS switch mechanism uses silver tungsten alloy contacts with a quick-make, quick-break action that minimises arcing during switching operations, extending contact life significantly compared to slow-make isolating switches used in older panel designs. Current ratings at 40°C ambient (AC-23A utilisation category) reflect the elevated temperature conditions found in Saudi Arabia's electrical panels during summer, where panel internal temperatures frequently exceed the standard 35°C reference temperature used in European switch ratings. The UTS is available with padlockable handle for security lockout, auxiliary contact block for position feedback to SCADA or BMS systems, and motorised operator for remote operation in unmanned substations and automated facilities.

In Saudi Arabia, isolator switches are a mandatory electrical safety requirement in industrial and commercial panel designs per SEC regulations, Saudi Building Code electrical requirements, and the National Electrical Code as adopted in the Kingdom. The UTS is specified by Saudi electrical contractors as the preferred LS Electric solution for main incomer isolation, providing safe circuit de-energisation during maintenance and fault conditions at ratings from small distribution board incomers through to large industrial switchgear main isolators. Razz Middle East stocks the UTS across common ratings and pole configurations, providing same-day availability on the most frequently specified sizes.

Razz Middle East offers the UTS with full technical documentation, Saudi Electrical Code compliance guidance, and volume pricing for contractors procuring multiple units on project orders. Our team provides cross-reference support for customers replacing ABN or Socomec equivalent isolators with UTS units.
