| Description | Voltage Monitor Relay; Undervoltage (brownout); 220...240V AC; 1 Form C (SPDT) |
| Datasheet | Download Datasheet |
The Littelfuse SSAC KVM6 is a single-phase undervoltage monitor for 220-240 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: 156-199 V AC adjustable; reset at 209 V AC fixed. Output: 8 A resistive at 120 V AC; 1/3 hp at 120/240 V AC. Contacts: 1 Form C (SPDT). Indicator: LED, green when the output is energized.
Mounting: Surface Mount; Quick Connect - 0.250" (6.3mm). Dimensions: 50.8 x 50.8 x 30.7 mm (2 x 2 x 1.21 in). It operates from -25 to +55 °C and stores from -40 to +85 °C.
