The Rich Solar Single Pole Thermal Circuit Breaker is a resettable DC breaker offered in nine ratings, from 30A (RS-CB30) to 250A (RS-CB250). Rich Solar rates it at 30VDC and 48VDC, with a 3,000A interrupt rating at 30VDC.
It's sealed and rated IP67, ignition protected to SAE J1171, and meets SAE J1625, ABYC E-11 and CE. Rich Solar lists it for auxiliary and accessory circuits in trucks, buses, RVs and marine systems, as well as battery chargers, DC audio systems and compartment and bilge areas.
The breaker protects DC circuits from overloads and short circuits and can interrupt up to 3,000A at 30VDC. Choose 30A, 40A, 60A, 80A, 100A, 120A, 150A, 200A or 250A to match the cable and load you're protecting.
A push-to-trip button lets you test the breaker or shut a circuit off by hand, and the reset lever restores power after a trip. You don't need to replace anything after a fault the way you would with a fuse.
The housing is UL94 V-0 flame-retardant thermoset plastic, sealed and rated IP67. Covered units with surface-mount bases have thermoplastic elastomer stud insulators. The breaker works from -25°F to 180°F (-32°C to 82°C).
Mount it on a panel or a flat surface. Connections use 1/4"-28 or 3/8"-16 threaded studs, with a maximum terminal torque of 50 in-lbs (5.6 N·m).
RVs and boats. Protect auxiliary and accessory circuits, including breakers placed in compartment and bilge areas.
Trucks and buses. Guard accessory circuits, battery chargers and DC audio systems with a breaker you can reset by hand.
A fuse has to be replaced once it blows. This breaker resets with a lever, and its push-to-trip button doubles as a manual shut-off for maintenance. It also carries an IP67 rating and SAE J1171 ignition protection.
Pick the rating that matches the circuit you're protecting, and stay within 48VDC. The 3,000A interrupt rating applies at 30VDC. Tighten terminals to no more than 50 in-lbs (5.6 N·m).
Nine: 30A, 40A, 60A, 80A, 100A, 120A, 150A, 200A and 250A. Each option is its own model number, from RS-CB30 to RS-CB250.
Yes. It meets SAE J1171 ignition protection, and Rich Solar lists compartment and bilge areas among its uses.
Use the reset lever to restore power once you've cleared the overload or fault. The push-to-trip button turns the circuit off by hand.
The Rich Solar Single Pole Thermal Circuit Breaker gives DC systems manual-reset protection in nine ratings, with IP67 sealing, ignition protection and a 3,000A interrupt rating at 30VDC. If you'd like help choosing the right rating for your cable and load, the Outbound Power team is happy to help.
