The BA45J-MT80/Z3 REX 45KVA 600-120/208V 3PH ISO Transformer is a high-performance isolation transformer designed for optimal efficiency and reliability. Ideal for various industrial applications, it ensures safe power distribution while minimizing electrical noise. Compact and durable, this transformer meets stringent quality standards, making it perfect for your electrical needs.
Yes. The BA45J-MT80/Z3 is designed with a 600 V primary, which is the standard industrial distribution voltage in Canada. It steps down to 120/208 V for powering three-phase and single-phase loads, making it well suited for Canadian industrial and commercial facilities operating on 600 V services.
Yes. As an isolation transformer, the BA45J-MT80/Z3 provides galvanic isolation between the primary (600 V) and secondary (120/208 V) windings, meeting the CEC definition of a separately derived system. This means the secondary neutral must be bonded and grounded at the transformer in accordance with CEC Section 10 — our team can assist with code compliance questions.
A general rule is to total the full-load amperage of all connected equipment on the 120/208 V secondary and ensure it does not exceed approximately 125 A (three-phase) or the equivalent single-phase load. You should also apply a demand factor and include a safety margin of 20–25% for inrush currents from motors or other inductive loads.
