Switch Disconnector according to IEC/EN 62626-1

GHG 26 (10 – 160 A) and GHG 981 (25-80 A) for Industrial- & Ex-Applications

In what applications is IEC 62626-1 compliance required?New disconnector accrding to IEC/EN 62626-1

This standard applies to various applications to provide isolation of electrical equipment, namely motor circuits. Switch disconnectors used in these applications are commonly known as “safety switches”, “maintenance switches”, or “isolators” and are placed in close proximity to the equipment. Position switches, inspection switches, and other switches are not covered by this standard.

What are the requirements of the standard?

The standard divides products into two classifications:

  • Class 0 for general use
  • Class 1 for harsh and rough/ heavy duty conditions.

All products installed in ATEX/IECEx hazardous areas should be rated for Class 1. Class 1 requirements include minimum ratings for mechanical strength, IP protection, tamper resistance, heat/vibration/corrosion resistance, switching capacity, and locking capability.

How can safety switches meeting the standard be identified?

Sympol according IEC/EN 62626-1Switch disconnectors complying with the new standard IEC/EN 62626-1 can be easily identified by two mandatory labels located on the switch enclosure. First, the symbol “switch disconnector” must be present on the enclosure. Additionally, the label “Safety Switch” must be on the front of the enclosure.

Our Switch disconnectors fulfils all requirements of the IEC/EN 62626-1. So they can be used reliably in harsh environments for Zones 1,21, 2, and 22 as well as any industrial application!

By meeting the specific conditions of class 1 we can confirm the following characteristics:

  • Meet all requirements of IEC/EN 62626-1 and the Directive 2006/42/EC (Machinery Directive)
  • High IK09 impact resistance • Protection class IP66
  • AC-3 switching capacity
  • 3 times lockable in OFF position
  • Interlock to prevent the opening of the cover in “OFF” position
