General Description:
27v nom, 1.0 amp max input, sensing signal v3 phase, 4 wire ac signal, signal not to exceed 16v rms, trip point power to contacts 2 and 3 disengaged when current in any phase has risen to 125 nom load bank capacity, trip time less than 50 m sec, 50-400 hz frequency, m65deg to 125 degrees f, inductive or resistive load, connections 6and 8 mode auto-power to load is controlled by sensing signal, closed-manual-sensing control deactivated, connections 2and 3 ac input appears full wave rectified between contactsprovided sensing signal is not at or above trip point or mode is manual, connections 3 and 9 momentary close resets power to load, connections 1 and 3 must be closed for sensing control, connections 10, 11 and 12 3 phase sensing signal connection, terminal 8 is common, connections 4 and 5 ac input power
