Littelfuse 102A Monitor 320720-756 This compact solenoid valve requires

This compact solenoid valve requires a minimum pressure drop of 1 psi to ensure the pilot-operated disc opens completely

Featuring a 3/8" NPT connection and a durable rubber seat poppet

Use a manometer to verify the inducer is pulling the required WC (water column) pressure listed on the switch body

it ensures precise disconnection of the start capacitor once the motor reaches sufficient angular velocity

Field-Upgradable Flexibility: Selectable pressure ranges and output types (current or voltage) reduce inventory requirements and allow for on-site adjustments

Littelfuse 102A Monitor 320720-756 This compact solenoid valve requiresThe Littelfuse 102A Monitor is an industrial grade, auto ranging 3 phase voltage monitor engineered to protect motors from critical power anomalies in 190480V AC applications. Utilizing a proprietary microcontroller based voltage sensing circuit, this unit provides constant surveillance of incoming power to detect phase loss, voltage unbalance, and phase reversal conditions. Unlike standard analog monitors, the 102A automatically selects between 200V
