The White Rodgers RBM Type 154, model 90-165, is a heavy-duty, 3-pole electromechanical contactor designed for reliable switching of high-power loads. With a robust 30-amp contact rating and a 208/240VAC coil, this component is an industry-standard workhorse for commercial and residential HVAC systems, industrial machinery, and agricultural equipment.

This contactor acts as a high-capacity relay, using a low-voltage control circuit to safely switch a high-voltage power circuit, making it essential for compressors, motors, and heating elements.

Key Features & Benefits

• 30 Amp Contact Rating: Handles significant electrical loads, making it ideal for large air conditioning units, heat pumps, and industrial equipment.

• 3-Pole Design: Allows for the simultaneous switching of three separate circuits or a 3-phase power supply. The standard configuration is one pole for each power leg and one for the compressor.

• 208/240 Volt AC Coil: The coil voltage matches common commercial and residential power supplies, ensuring broad compatibility. The coil draws power only during the brief moment of engagement, promoting energy efficiency.

• Durable Construction: Features a robust, thermoplastic enclosure that is dust-tested and drip-proof, protecting the internal components for long-term reliability.

• Silver Cadmium Oxide Contacts: Provide excellent resistance to welding and erosion, ensuring a long electrical life and dependable performance under frequent switching and high inrush currents.

• Easy Installation: Clearly marked terminals (L1, L2, L3, T1, T2, T3) and a straightforward design allow for quick and error-free replacement or new installation.

• Plug-In & Bolt-On Options: Versatile mounting styles to fit various application requirements.
