BC30B-Q/Z REX 30KVA 208-600/347V 3PH TRANSFORMER

The BC30B-Q/Z supports a primary voltage range of 208–600 V, which covers the most common Canadian three-phase service voltages: 208 V, 240 V, 480 V, and 600 V. Select the tap that matches your available supply voltage. If you are unsure which tap is correct for your installation, send us your site's service voltage and we'll confirm the right configuration.

At 30 kVA three-phase, this transformer can supply a full-load current of approximately 50 A at 347 V secondary. To determine whether it suits your application, total the kVA demand of all connected loads (lighting, motors, equipment) and apply a standard diversity/demand factor per CEC Section 8. If your calculated demand is at or below 30 kVA, the BC30B-Q/Z is a suitable fit. Our specialists can assist with a quick load review — reach out with your load schedule.
