The R. STAHL Series 8579/31 sockets for Zone 1/21 in 4- and 5-pole versions have full AC-3 switching capacity up to 63 A. The high degree of protection (IP66) ensures maximum protection against the ingress of dust and water in any application situation. 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 a mechanical locking device and a handle that can be locked in the 0 or I position, is an additional safety feature.
