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.
The standard divides products into two classifications:
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.
Switch 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.
All features of our switch disconnectors are are shown in our new brochure – download here –
