2P DC Circuit Breaker 20A 500V, DIN Rail Mount Solar Disconnect Switch for PV System, Battery, Inverter, RV & Home Electrical Panel

Product description

Technical Data

Operating voltage (Ue) 1P=250 V DC, 2P=500 V DC Rated insulation voltage (Ui) 1,000 V DC Breaking capacity (Icu) 10 kA Impulse voltage (Uimp) 4 kV Electrical connection By the bottom for In and Out Standards IEC 60947-2/ EN 60947-2

Adjustable Installation Buckle

Suitable for 35mm DIN rail, easy to install and hard to fall off.

Connection

Tightening Torque: 2.5 N.m

Copper Cables Rigids: 1-25 mm²

Copper Cables Flecibles with freeule: 1-16 mm²

Cu/Al Terminal: 50 mm²

Easy installation

Solar dc disconnect, installed between solar panel and solar inverter, can realize faster and safer installation, plug and play.

Pure copper coil

When the circuit fails, excessive current is generated, and the circuit breaker can quickly cut off the power supply to realize short-circuit protect.

Warm reminder: Safe electricity usage starts with correct selection

Thank you for choosing this type of circuit breaker. To ensure electrical safety and extend the product’s lifespan, we suggest:

Please increase the amperage of the circuit breaker you actually need by more than 20% when making your purchase. This can effectively deal with the instantaneous inrush current when the electrical appliance starts up, prevent the circuit breaker from overheating due to long-term overload operation, and protect the safety of your electrical appliances and circuits.
