RF04W38 3-Pole 30A 220V AC Contactor (Definite Purpose Contactor)

Designed to provide reliable switching in air conditioning, refrigeration and industrial systems, the RF04W38 Definite Purpose Contactor is a heavy-duty power relay. With its 3-pole (3 Poles), 30A FLA and 40A RES rating, it offers superior performance and safety in controlling compressors and fan motors that draw high current.

High Current Capacity and Durable Coil Design

This contactor operates with a 220 VAC coil voltage and is fully compatible with standard industrial and commercial refrigeration systems. With 50/60Hz frequency support, it is resistant to mains fluctuations. Its sturdy brass alloy terminals (L1, L2, L3 input and T1, T2, T3 output) and heat-resistant housing minimize arcing and provide long-lasting switching.

Practical Note for Field Technicians

Technician Note: When installing in your system, after connecting the L1, L2, L3 phase inputs and T1, T2, T3 motor/compressor outputs, make sure you tighten the terminal screws to the proper torque. Loose connections cause heating and arcing over time and shorten the life of the contactor. Before energizing the coil terminals, make sure your control circuit is 220V. During replacement, always confirm with a multimeter that power is completely cut off at the main breaker.
