| Manufacturer Product Number | HLVA6I23 |
| Description | Voltage Monitor Relay; Undervoltage (brownout); 100...240V AC |
| Datasheet | Download Datasheet |
The Littelfuse SSAC HLVA6I23 is a single-phase undervoltage monitor for 100-240 V AC supplies: it drops its relay out on a brownout and re-energizes when the voltage recovers, protecting motors, solenoids and other sensitive equipment.
Trip point: 170-220 V AC adjustable; reset at 105% of the trip point. Trip delay: Fixed at the factory, 1-20 s. Restart delay: 3-300 s adjustable. Output: 30 A (NO) / 15 A (NC) general purpose and resistive at 125/240 V AC; 20 A / 10 A at 28 V DC; NO 1 hp at 125 V AC, 2 hp at 240 V AC. Contacts: 1 Form C (SPDT), isolated.
Mounting: Surface Mount; Quick Connect - 0.250" (6.3mm). Dimensions: 76.7 x 51.3 x 38.1 mm (3 x 2 x 1.5 in). It operates from -40 to +60 °C and stores from -40 to +85 °C.
