Product Description

The Bentek Solar Breaker Universal Safety System (BUSS) is a floor-mounted

recombiner. It is designed for large PV solar systems (250KW or greater) and is

intended for installation next to the inverter. It is comprised of multiple UL-rated

1000VDC circuit breakers contained in one easy-to-install compact enclosure.

The BUSS

provides an unmatched safe and convenient means of isolating and

diagnosing individual DC portions of a PV system for routine maintenance and

troubleshooting.

Maximum current through each circuit of the BUSS is determined by the size of

the circuit breaker and the proper application of deration factors consistent with

NEC code.

Each source circuit is protected separately from overcurrent limits through circuit

breakers according to the requirements of the National Electric Code (NEC). Each

circuit breaker has a switch that can be used to disconnect that breaker.

The circuit breakers provide maximum performance and safety with UL489

breakers. The breaker itself serves as a disconnect in addition to providing circuit

protection.

The 1000V BUSS is designed for up to fourteen circuit breakers that are installed

in two banks. Circuit breakers are available in the following sizes: 125A, 150A,

175A, 200A, 225A, 250A, 300A, 350A, and 400A. Multiple sizes of circuit breakers

can be installed in the same BUSS.

When the BUSS contains twelve or fewer circuit breakers, it is housed in a

79-inch high enclosure. When the BUSS contains thirteen or fourteen circuit

breakers, it is housed in a 87-inch high enclosure.
