The ASXP-LS current switches are a combination current transformer and signal conditioner designed specifically for monitoring large loads. The switches feature electromechanical relay output, external power source and simple field setpoint adjustment. The mechanical relay contact provides a durable alarm or interlock, which improves safety and system reliability, while the selectable “Fail Safe” operation provides protection for critical loads. The switches are used to monitor large machines for over- or under-load conditions, detect open discharge lines and sense clogged filters. They can also monitor generators to shed noncritical loads when demand reaches a set level.
