The ATC Diversified SLH-440-ALE is a 3-phase monitor for 430-480 V AC systems. It drops its output relay out on phase loss, phase reversal and undervoltage and resets once the fault clears.
Adjustment: adjustable hysteresis, 0 to 15% below the pick-up setting. Trip delay: phase loss / reversal 2 s; undervoltage 2 s. Restart: 1 s. Reset: automatic upon correction of the fault.
Output: 2C DPDT, 5 A resistive, 345 VA inductive at 240 V AC. Mounting: surface mount (#8 screws), screw terminals. Indicator: LED, glows when all conditions are normal. Approvals: UL (E55826). It operates from 0 to +55 °C and stores from -45 to +85 °C.
