Bentek Solar Releases Breaker System for PV Power Plants

Inside this Article

[San Jose, CA] The Breaker Universal Safety System (BUSS) from Bentek Solar allows integrators to standardize utility-scale array layouts independent of the dc input configuration of a project’s central inverters. The freestanding BUSS unit is designed for grounded and ungrounded PV plants with input voltages up to 1,000 Vdc. It provides overcurrent protection and disconnect compliance per 2011 NEC Section 690.16. The product is configurable for up to 14 dc input circuits ranging from 100 A to 400 A and accepts 250–1,000 MCM conductors. The Eaton circuit breakers used on the BUSS input are 100% duty rated with 90°C-rated compression terminals that allow for potential reductions in the required cable and conduits. The BUSS output provides a universal connection to the inverter’s dc input. DC inputs may be monitored through RS485 or Ethernet interfaces located within the enclosure.
