Product description

This three-phase air-insulated load break switch is engineered for reliable interruption of load current in medium voltage electrical distribution networks. The device features a mechanical pole switching mechanism integrated with visible insulating supports to ensure safe operation under load conditions. Its robust mechanical construction supports frequent switching operations essential in power distribution and industrial applications.

  • Designed as a three-pole switching device with an air-insulated configuration, providing medium voltage load break capability.
  • Operated via a mechanical linkage system, allowing controlled and visible actuation of load switching.
  • Suitable for electrical distribution panels in industrial, utility, and biomanufacturing facilities where medium voltage control is critical.
  • Dimensions measure approximately 48 inches (L) x 24 inches (W) x 36 inches (H), with a weight near 150 lbs, facilitating integration into standard switchgear assemblies.
  • Essential for applications in biotechnology and bioprocessing plants where reliable power switching supports sensitive instrumentation and process control.
  • Supports research domains requiring precise electrical distribution control such as molecular diagnostics, clinical laboratories, and synthetic biology facilities, ensuring uninterrupted power management for critical equipment.

This switch is a fundamental component in medium voltage electrical distribution systems, widely used to improve operational safety and equipment protection in biomedical engineering, live-cell imaging laboratories, and molecular biology research environments. Its air-insulated design minimizes maintenance while providing stable performance in complex electrical infrastructures.

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
