BA225H-Q/E3R/Z3 REX 225KVA 480-600/347V 3PH TRANSFORMER
The BA225H-Q/E3R/Z3 REX 225KVA transformer is designed for optimal performance in 480-600/347V 3-phase applications. With advanced technology and durable construction, this transformer efficiently handles your power needs, ensuring reliable operation for commercial and industrial settings. Trust in top-quality engineering to maximize your electrical systems.
Yes. The dual primary rating (480–600V) means the transformer can be tapped for either a 480V or 600V 3-phase source, which is ideal for Canadian facilities where 600V service is the standard utility delivery voltage. The correct primary tap must be selected and connected by a qualified electrician before energizing the unit.
The 'Z3' suffix indicates the transformer is equipped with an electrostatic (Faraday) shield between the primary and secondary windings. This shield reduces capacitive coupling and helps attenuate electrical noise and transient voltages — particularly useful in applications with sensitive electronics, PLC systems, or variable frequency drives (VFDs) connected downstream.
Rex transformers (including the BA-series) are considered a legacy or hard-to-find line in many markets. Northern Breaker Group specializes in obsolete and hard-to-find electrical equipment across Canada, with counter locations in Calgary, Edmonton, and Vancouver. Contact us with your full model number and we'll advise on availability — whether new-old-stock, reconditioned, or a compatible cross-reference.
