Renogy 160A 2P DC Molded Case Circuit Breaker

 DESCRIPTION

【DOUBLE SECURITY】 Equipped with both the thermal and magnetic tripping mechanism for reliability and safety.
【SAFE TO USE】 Designed for reversible connection and can work under bidirectional current.
【DURABLE FOR USE】 After the circuit breakers is disconnected, only reset is needed and there will be no damage.

【QUICK TO INSTALL】 Equipped with DIN rail and panel mounting for easy installation.

 

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.

RELIABLE AND SAFETY

Equipped with both the thermal and magnetic tripping mechanism for reliability and safety, along with the certification of CE, RoHS, CB, TUV.

DURABLE FOR USE

Excellent product quality and strong service life. Material and workmanship warranty for 1.5 years.

1.How to choose suitable circuit breaker?
 

For controller/inverter/DCdevice

1. Determine the maximum continuous operating current=watt/voltage

2. Maximum current = 1.25 x maximum continuous operating current

3. Select the circuit breaker whose rated current is greater than and closest to the maximum current

For solar panel

1. Determine short-circuit current

2. Maximum current = Short-circuit current x 1.25 x 1.25

3. Select the circuit breaker whose rated current is greater than and closest to the maximum current

2. What size wire will it accept?
 
The circuit breaker accepts wire of 4 AWG~4/0 AWG.
3. What is the difference between 1P and 2P circuit breaker?
 

1P connects on the live wire only.

2P connects on both live wire and neutral wire, so it can cuts them at the same time.

Normally, 2P can afford greater rated current and working voltage than 1P.

4. What is the difference between fuse and circuit breaker?
 

Circut breaker:

Functions: overload/short circuit protection and active disconnection can be realized

Breaking time: small current delay trip, large current instant trip

Rated operating voltage: 250V/1000V

Replacement: after disconnecting, only reset is required, don't need to replace it

Fuse:

Function: overload/short circuit protection only

Breaking time: high current also has delay

Rated operating voltage: 72V

Replacement: Replacement is required immediately after breaking

5. Where is the circuit breaker often connected in?
 
Combinar box, breaker box, home kits, etc.
