Littelfuse, Inc. Industrial Relays KVM4

The KVM4 is a single-phase undervoltage monitor protecting equipment from brownouts. It has an SPDT electromechanical relay rated for 8A resistive at 120VAC and 1/3 hp at 120/240VAC, with a mechanical life of 1 × 10⁶ and electrical life of 1 × 10⁵. The undervoltage setpoint is adjustable from 78 to 99VAC, with a fixed reset point of 104VAC. Input voltage range is 110 to 120VAC, consuming 2.5W at 132VAC. The device is enclosed in a 50.8 mm × 50.8 mm × 30.7 mm surface-mount housing with 0.25 in. (6.35 mm) male quick-connect terminals. An LED indicates output status. Circuitry is encapsulated, meeting IEEE C62.41-1991 Level A surge immunity. Isolation is ≥1500V RMS, insulation resistance ≥100 MΩ. Operating temperature: -25 to 55°C; storage: -40 to 85°C.
