Directly replaces part number 9003546005 for streamlined inventory management and maintenance
The low-voltage 24VAC coil is optimized for precise activation even during voltage fluctuations common in peak demand periods
a capacitor with a higher voltage rating (440V) can safely replace a 370V unit as long as the capacitance (45/4 MFD) and physical dimensions match
we recommend selecting the TR6 model specifically calibrated for lower tonnage
leak-proof performance
