R. STAHL Series 8579/ 31 sockets for Zone 1/ 21 in a 4- and 5- pole version have full AC- 3 switching capacity up to 63 A. The high degree of protection IP66 guarantees the highest level of protec-tion against the penetration of dust and water in any application position. Self- cleaning lamellar contacts provide optimum contact and the plugs can be inserted and removed in the zero position quickly and easily. The load disconnect switch, with mechanical locking device and a handle that can be locked in the 0 or I position, is an additional safety feature.
