E X - I N S T A L L A T I O N S W I T C H 16 A, 250 V Plastic ve<strong>rs</strong>ion for Zone 1 and Zone 21 The explosion-protected installation switches are for use in the Zones 1, 2, 21 and 22. The materials used have proved to be safe and reliable for both indoor and outdoor installations, in particular in chemical and off-shore plants. The robust housings are made of a modified polyamide material. The large actuator surface of the installation switch allows perfect operation, even when wearing working gloves. A protective collar prevents inadvertent operation. The toggle has a luminescent label which is in accordance with §7 of the Workshop Regulations and is also free from radioactive additives. Due to the external fixing facility, the switch can be installed easily while the cover is closed. Cable entry from the top is made possible by turning the base. In special cases a through wiring is possible as one can see on the illustration opposite. International approvals. Large toggle also for working gloves Safety standard IP66 Cable entry from the top or bottom Connecting terminals easily accessible 9.4
