Modine 5H0547510021 Orifice R-407C a 440V rated capacitor is

a 440V rated capacitor is a suitable upgrade for a 370V application as it offers a higher dielectric strength

and unit heater series

Environmental Protection: TEAO enclosure prevents dust and moisture ingress

Reduced Operational Noise: Corrects "thumping" sounds or intermittent startup issues common in failing motor modules

This assembly is designed for specific furnace chassis

Modine 5H0547510021 Orifice R-407C a 440V rated capacitor isThe Modine 5H0547510021 Orifice is a precision engineered Natural Gas Main Orifice designed for consistent gas flow regulation in commercial and industrial Modine heating units. As a critical component in the burner manifold assembly, this orifice is calibrated to maintain the specific manifold pressure required for efficient combustion and clean flame characteristics. Built from high grade, corrosion resistant brass, it ensures long term reliability
