The Rex BA150B-Q/Z3 is a 150 KVA, 3-phase dry-type transformer rated for 208–600V primary / 347V secondary, making it well-suited for industrial and commercial installations where step-down or voltage conversion is required across a wide input range. Its 347V secondary output is particularly common in Canadian distribution systems for lighting and motor branch circuits.
Not sure if this transformer is sized or configured correctly for your application? Send us your project details and we'll help confirm the right fit.
The BA150B-Q/Z3's wide primary voltage range (208–600V) means it can accept input from a variety of upstream service voltages common in Canadian facilities — including 208V, 240V, 480V, and 600V 3-phase systems — without requiring a different transformer model. Always verify your specific primary voltage against the transformer's tap settings before energizing.
The Rex BA series is generally manufactured as a dry-type transformer intended for indoor or sheltered industrial environments. If your application requires outdoor installation, additional weatherproof enclosures or a transformer with an appropriate outdoor enclosure rating (e.g., NEMA 3R) would be needed. Contact us with your installation details and we can advise on the correct solution.
Rex transformers, including the BA series, can be difficult to source through standard distribution channels.
