B-LINE 4563PMURN – Frequently Asked Questions
1) Can the B-Line 4563PMURN UNIPAK capacitor bank be mounted outdoors?
Yes. The 4563PMURN carries a NEMA 1, 3R enclosure rating, so it works indoors or outdoors in a rain-exposed location. The housing is 14 gauge steel with a powder coat finish.
2) Does the 4563PMURN capacitor bank come with a fuse or disconnect, or do I need upstream protection?
It is a non-fused unit, so overcurrent protection and disconnecting means have to come from upstream in your installation. Plan the feeder breaker or fused disconnect around the 44.10A rating of the bank and the applicable capacitor circuit sizing rules in your jurisdiction.
3) Will the B-Line 4563PMURN work on a 480V three-phase system?
The unit is rated to 600V and is a three-phase capacitor bank, so 480V three-phase is inside its voltage rating. Keep in mind the 45 kVAR figure is the 240V rating, so check the delivered kVAR for the system voltage you are correcting before sizing.
4) What exact part number should I order for the 45 kVAR B-Line UNIPAK capacitor bank?
Order B-Line part number 4563PMURN. That is the 45 kVAR, 600V rated, three-phase non-fused UNIPAK in the B1 frame with a NEMA 1, 3R enclosure.
