Specifications

SRS series rotary switches are manufactured comply with IEC 62271-102, IEC 60265 standards.
Rotary switches are manufactured in 2 states 3 poles. It gives a possibility to use 3 states 3 poles with SES series earthing
switches.SRS series rotary switches allows to stand-alone use for safely breaking under no load conditions.
SRS series rotary switches are used together with circuit breaker for switching on-load and on short circuit or with contactors for on-load switching applications in safe.
