Renogy 160A 2P DC Molded Case Circuit Breaker
Description
The Suntree DC Molded Case Circuit Breaker is designed to protect DC electrical installations against overloads and short circuits with both the thermal and magnetic tripping mechanism equipped. Once a fault is detected, the circuit breaker automatically switches off the electrical circuit to prevent damage to wires and avoid the risk of fire.
The circuit breaker can also be manually opened under the full rated load without any damage when electrical maintenance needs to be performed. Engineered for reversible connection, the circuit breaker is allowed to be wired in either direction and functions under bidirectional current. The markings on the handle help identify the contact position of the circuit breaker at a glance. The special design enables easy installation on both the standard DIN rail and the vertical surface.

FAQ
How to Choose Suitable Circuit Breaker for Controller/Inverter/DC Device:
Determine the maximum continuous operating current as the wattage divided by the voltage.
Calculate the maximum current, which is 1.25 times the maximum continuous operating current.
Select the circuit breaker whose rated current is greater than and closest to the maximum current.
What Size Wire Will it Accept?
The circuit breaker accepts wire sizes ranging from 4 AWG to 4/0 AWG.
What is the Difference Between 1P and 2P Circuit Breaker?
1P circuit breakers connect to the live wire only.
2P circuit breakers connect to both the live wire and the neutral wire, allowing them to cut both at the same time. Typically, 2P circuit breakers can handle greater rated current and working voltage than 1P breakers.
What is the Difference Between Fuse and Circuit Breaker?
Circuit Breaker:
- Functions: Provides overload/short circuit protection and can actively disconnect the circuit.
- Breaking Time: Trips quickly for small currents, instant trip for large currents.
- Rated Operating Voltage: Typically 250V/1000V.
- Replacement: After disconnecting, only a reset is required, with no need for replacement.
Fuse:
- Function: Offers overload/short circuit protection only.
- Breaking Time: Can have a delay even for high currents.
- Rated Operating Voltage: Typically 72V.
- Replacement: Immediate replacement is necessary after breaking.
Where is the Circuit Breaker Often Connected In?
Circuit breakers are commonly connected in combiner boxes, breaker boxes, home kits, and similar installations.
