AC Isolation Switch LYAS5 Series
The EAS Series AC isolation switches are suitable for switching on and off AC circuit systems, such as in PV systems and air conditioning systems. This weatherproof disconnector is particularly suited for outdoor installation and can achieve IP66 protection level. The base mounted mechanism provides more convenient termination and wiring room.
According to EN60947-3 AS/NZS 60947-3.
