Littelfuse 201A Monitor 328140-751 Heavy-Duty Ports: Equipped with 3/4"

Heavy-Duty Ports: Equipped with 3/4" NPT connections and inlet/outlet screens to prevent debris from fouling internal valve seats

Using an OEM-spec 280 MFD capacitor ensures that the motor windings receive the precise phase shift needed for rapid acceleration

Its dual-stage logic supports precise low-fire operation

it is standard professional practice to inspect and replace any secondary seals or transition gaskets during the heat exchanger service

This tamper-resistant unit is specifically engineered for the RA 2000 series

Littelfuse 201A Monitor 328140-751 Heavy-Duty Ports: Equipped with 3/4"The Littelfuse 201A Monitor is a professional grade 3 phase plug in voltage monitor engineered to protect induction motors from catastrophic power line conditions. This unit features a microcontroller based voltage sensing system that provides auto ranging capabilities across 190480V AC at 50 60Hz. By automatically detecting the system voltage and selecting between the 200V and 400V scales, this phase monitoring relay eliminates manual configuration
