Ex-safety switches

Application area

The explosion-protected installation switches are for use in the Zones 1, 2, 21 and 22.

Product features

.Full AC-3 switching capacity.
: Isolating properties according to EN 60947-4-1 with compulsory opening of the main current contacts.
.EMERGENCY STOP version is also available.
. Installation-friendly design and easily accessible connection terminals.
: Protected against inadvertent switching on by the integrated locking facility.

GHG 26 switches (10-180 A) and are now confirmed to comply with the new standard IEC 62626-1, requirements Class 1.

The standard divides products into two classifications: Class 0 for general use and 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
