| Datasheet | Download Datasheet |
The ATC Diversified SLE-120-ALE is a 3-phase monitor for 120 V AC systems. It drops its output relay out on phase loss, phase unbalance and undervoltage and resets once the fault clears.
Trip points: undervoltage 95-115 V AC; unbalance adjustable from 2 to 10% unbalance. Adjustment: lock shaft adjusted. Trip delay: phase loss / reversal 0.5 s; undervoltage 0.5 s. Restart: 60 ms. 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.
