The BC15B-Q/Z REX 15KVA transformer is designed for 208-600/347V three-phase applications, providing reliable power conversion and efficiency. Ideal for industrial and commercial settings, this transformer ensures optimal performance and longevity. With robust construction and advanced technology, it’s the perfect choice for your electrical needs at Alberta Breakers & Supply Co Ltd.
347 V is a standard Canadian distribution voltage derived from a 600 V three-phase, four-wire wye system (600 V ÷ √3 ≈ 347 V). It is commonly used in commercial and industrial lighting circuits throughout Canada, making the BC15B-Q/Z a natural fit for Canadian building electrical systems where 347 V fluorescent or LED lighting loads are present.
A quick estimate: total load KVA = (amps × volts × 1.732) ÷ 1,000. As a general rule, size your transformer so the connected load does not exceed 80% of its KVA rating for continuous duty — meaning the BC15B-Q/Z is best suited for continuous loads up to approximately 12 KVA. If you're unsure, share your load schedule with our team and we'll help confirm the right sizing.
