BC45J-M/Z3 REX 45KVA 600-120/208V 3PH ISO TRANSFORMER
The BC45J-M/Z3 REX 45KVA 600-120/208V 3PH ISO TRANSFORMER is a reliable solution for your electrical needs, providing efficient voltage transformation for three-phase systems. With high-quality construction and robust performance, this transformer ensures optimal power delivery and enhanced safety for your applications. Ideal for commercial and industrial settings.
At 45 kVA on a 208V three-phase secondary, this transformer delivers approximately 125A of full-load secondary current (45,000 ÷ (208 × √3) ≈ 124.9A). This makes it suitable for feeding a downstream 100A or 125A-rated panelboard on a separately derived 120/208V system.
The isolation design provides galvanic separation between the 600V primary and the 120/208V secondary, which suppresses electrical noise and transients, improves safety for sensitive equipment, and creates a separately derived system as defined under the Canadian Electrical Code (CEC). This is commonly required in healthcare, data, and precision manufacturing environments.
