The BC30B-N1/Z REX 30KVA Transformer is designed for reliable three-phase power distribution. Operating within a voltage range of 208-400/231V, it ensures efficient energy conversion for various applications. Ideal for industrial and commercial use, this transformer provides robust performance to meet your specific electrical requirements. Trust REX for quality and durability.
The BC30B-N1/Z delivers a 231V three-phase secondary output from a 208–400V primary. This makes it ideal for industrial and commercial applications where equipment requires a specific stepped voltage — such as imported machinery, motor control centres, or process equipment rated for non-standard voltages. Contact our team to confirm suitability for your specific load.
As a general rule, your transformer KVA rating should meet or exceed your connected load. For a 30 KVA transformer like the BC30B-N1/Z, calculate your total three-phase load (amps × volts × 1.732) and ensure it falls within the 30 KVA limit — with a safety margin of 20–25% recommended for continuous loads. If you're unsure, share your load details with us and we can advise.
REX transformers, including the BC30B series, can be difficult to source through standard distribution channels.
