SunGold Power 160 Amp DC Breaker
The SunGold Power 160 Amp DC Breaker (SG-C160A) provides overload protection, short-circuit protection, and manual power isolation for battery-based solar and energy storage systems. Its 160A rating and two-pole molded-case design make it suitable for compatible DC circuits connecting battery banks, inverters, and other high-current equipment.
SunGold Power 160 Amp DC Breaker Features
160A Rated Current - Designed for high-current DC applications, including compatible battery and inverter circuits.
Overload and Short-Circuit Protection - A thermal-magnetic trip mechanism helps protect connected wiring and equipment from excessive current and short-circuit faults.
Manual Circuit Isolation - The clearly marked ON/OFF handle provides a convenient disconnect point for maintenance and system servicing.
Two-Pole DC Design - Features a 2P configuration with a rated operating voltage range of 12–500V DC, subject to the installation requirements in the manual.
Molded-Case Construction - A molded housing supports dependable circuit protection in solar energy storage, off-grid power, and backup power installations.
Push-to-Trip Button - A front-mounted red test button allows the breaker’s tripping mechanism to be manually activated.

Frequently-Asked Questions
What does this breaker protect against?
The SG-C160A provides overload and short-circuit protection for appropriately rated DC circuits. It also provides manual circuit isolation for maintenance.
Can it support battery charging and discharging?
Yes. The manual describes operation with current flowing in either direction, but the ultimate short-circuit breaking capacity changes with current direction: 25kA for the specified forward-current configuration and 15kA for reverse current. System selection must account for these limits.
How must the breaker be mounted?
The breaker must be installed upright on a vertical mounting surface, with the arc chamber at the top. The manual prohibits horizontal and upside-down mounting. Installation must follow the specified wiring diagrams and be performed by qualified personnel.
Where should the battery and inverter be connected?
The manual’s recommended arrangement connects the battery or DC power source to the upper LINE terminals and the inverter or other load to the lower LOAD terminals. Follow the manual’s connection diagrams and breaking-capacity requirements.
Does a 160A rating mean it can carry 160A at every temperature?
No. The manual provides temperature correction factors that affect usable current capacity. The operating temperature, cable sizing, and installation conditions must be considered when selecting the breaker.
