| Description | Phase Monitor Relay; 3-Phase; (525...625)V AC; 2C DPDT |
| Datasheet | Download Datasheet |
The ATC Diversified SLA-575-ALE is a 3-phase monitor for 525-625 V AC systems. It drops its output relay out on phase loss, phase reversal and undervoltage and resets once the fault clears.
Trip points: undervoltage 436-519 V AC (one phase low); 473-563 V AC (all three phases low). Adjustment: lock shaft adjusted; tracks the operating-voltage setting (one phase below 83% or all three below 90%). Trip delay: phase loss / reversal 2 s; undervoltage 2 s. Restart: 1 s. Reset: automatic upon correction of the fault.
Output: 2C DPDT, 3 A general purpose at 120 / 240 / 600 V AC; 480 VA at 600 V AC. Mounting: surface mount (#8 screws), screw terminals. Indicator: LED, glows when all conditions are normal. Approvals: cULus Listed, Industrial Control Equipment 496Y (E55826), CSA. It operates from 0 to +55 °C and stores from -45 to +85 °C.
