Trace Engineering solar power DC controls

Circuit Breakers or Fuse Blocks
Solar power control using Trace DC-175/250 disconnect

The DC250 and DC175 Circuit Breaker
Meet code with Trace's
DC disconnect/over current module.

Now it's easier to meet National Electric Code requirements
with a Trace DC175 or DC250.
These modules are designed to link with Trace SW and DR series inverter systems.

Battery disconnect: An easy way to isolate inverter and battery

Meets National Electrical Code requirement for "means of disconnection."

No exposed "hot" terminals

Doesn't need ring terminal lugs

Over current protection: DC circuit breakers UL listed for up to 125VDC

Extremely low voltage drop (less than most fuses or current shunts)

Rated for interrupting high fault current (up to 25,00 amps at 65 VDC)

Easy to reset

No exposed "hot" terminals

Room for expansion

Optional second main breaker accommodates dual inverter systems

Second breaker can be field installed

Space allows for DC current shunts

Optional bonding block simplifies wiring and grounding

Bonds negative conductor to grounding system at single point

Lugs to terminate four 4/0, two #1/0, two #2 and four #4 cables

Four Auxiliary breaker positions

Optional 15-amp DC breaker for small DC loads or equipment room light

Optional 60-amp DC-rated breaker for PV array disconnect, charge controller, etc.

UL listed for DC systems up to 125 VDC

Rated for interrupting high fault current, up to 25,000 amps at 65 VDC

Easily accessible #10-32 stud terminals

Note: Products are listed by UL and/or ETL to UL specifications
Year 2000 Note: Trace products do not utilize date sensitive chips. Therefore inverters and other Trace equipment are not susceptible to Year 2000 complications.

FUSE BLOCKS

DC fuseblock for solar power system control Class T Fuse Block with Fuse

The fuse block is placed between your battery and your inverter positive cable to provide over-current protection for your inverter. They are not as efficient as the above Trace DC175/250 circuit breaker, but they do work and they will protect your inverter. Provides the maximum interrupting capacity (AIC) required by the National Electrical Code. Designed for easy installation in new or existing systems. Simply cut cables and install or order the post-type terminal to accept cables with ring terminals. Fuse included. Replacement fuses are available.

The size of your inverter will dictate the fuse size you order. We can assist you with this determination.

Trace Fuse Block has a DC rated class T fuse in a protective holder with slide-off cover.
Available in 400, 300, 200, and 110 amps.
