A combination current transformer and signal conditioner designed specifically for monitoring large loads, ASXP-LS current switches feature an electromechanical relay output, external power source, simple field setpoint adjustment, and easy installation. The mechanical relay contact provides a trouble-free, durable alarm or interlock, improving safety and overall system reliability, while the selectable “Fail Safe” operation provides protection for critical loads.
The UL, CUL, and CE compatible 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 non-critical loads when demand reaches a set level. Key features inlcude a split-core housing that allows the unit to be installed over existing conductors, large aperture (2.3 x 3.42 in.) to accommodates conductors and multiple wires per phase, adjustable load start delay for high-inertia loads, and four models with trip points between 200 and 1,600 A.
