Technical Data
| MY R. STAHL | 8579A |
| Product Type | 8579/31-406 |
| Highlights | Reliable load disconnect switch with easily visible, lockable handle and display of the switching position An integrated auxiliary contact for control and signalling purposes, can be optionally enhanced using pluggable Ex e or Ex i auxiliary contacts that are easily retrofittable Large temperature range of use High mechanical impact and shock resistance Perfect protection against penetration of liquids and dusts 3D data for download on the website |
| Functional Description | 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. |
