Electrical solutions provider MV Switchgear, a division of ACTOM, has launched its latest product, the SBV4XE switchgear. Developed as a successor to the SBV4 and SBV4E models, which are withdrawable pattern switchgear ranges that are described as low profile, compact, robust and adaptable, making them ideal for applications with limited space constraints.

The company notes the following updated features of its new product:

  • Enhanced mechanisms: The spring and cam follower mechanisms have been redesigned to utilise alternative materials, reducing costs while maintaining reliability
  • Efficient operations: The opening and closing releases require less energy, resulting in improved energy efficiency compared to previous SBV models
  • Reduced maintenance: With a lower parts count, the circuit breaker operating mechanism requires less maintenance, leading to reduced overall costs
  • Cost-competitive assembly: The vacuum interrupter pole assembly is more cost-competitive, ensuring affordability while maintaining quality
  • Emission reduction: Arc cooling pressure relief devices have been integrated into the housing assembly, mitigating emissions during internal arc faults
  • Optimised manufacturing: The housing assembly is now bolted and riveted instead of welded, streamlining production and offering inherent corrosion resistance
  • Lightweight and durable: Most components are manufactured using aluminium and zinc-coated steel sheeting, providing corrosion resistance and enhanced galvanic bonding properties
  • Improved circuit breaker carriage: The redesigned carriage features a swivel-wheel chassis, allowing for 360o rotation and ease of manoeuvrability outside the housing assembly
  • Enhanced gears: The circuit breaker mechanism gears combine polymeric and steel materials, resulting in an 80% reduction in steel usage compared to traditional gears
  • User-friendly design: The circuit breaker carriage latching, interlocking and racking mechanism has been redesigned to enhance ease of operation, simplicity, and functionality
  • Advanced current transformers: The ring bar and base current transformers (CTs) use epoxy resin insulation with an earth-screened bar primary and toroidal core, or ring-type, CTs.

"The SBV4XE represents a significant leap forward in switchgear technology. Its innovative features and cost-saving enhancements offer our customers unparalleled value, reliability and ease of use," stated ACTOM switchgear division CEO Donovan Stevens.
