BC10B-N1 REX 10KVA 208-400/231V 3PH TRANSFORMER

To size correctly, total your connected three-phase load in watts or VA and divide by 1,000 — you'll need a transformer rated at or above that figure. For a 10 KVA unit, the full-load current on the 231 V secondary is approximately 25 A (three-phase). If you're unsure, send us your load schedule and our team can help you confirm whether the BC10B-N1 covers your requirements or whether a larger unit is needed.

Yes — Rex transformers are designed for the North American market and the BC10B-N1 can be installed in CEC-compliant industrial and commercial distribution systems. As always, installation must be performed by a qualified electrician and the installation must meet the applicable provincial electrical code requirements, including appropriate overcurrent protection on both the primary and secondary sides per CEC Section 26.
