Photonic Universe CB250 250A DC Circuit Breaker 12/24/48V | 4Boats

Photonic Universe CB250 resettable 250 A thermal overcurrent DC circuit breaker for 12 V, 24 V, 48 V systems — suitable for marine, automotive and off-grid applications.

• Suitable for a wide range of DC applications, including between off-grid inverter DC input and batteries, DC power distribution, charging circuits and other automotive and marine uses.
• Circuit breaker specifications: Rating: 250 A; Type: Thermal overcurrent protection device; Material: Thermal plastic (UL94 V-0).
• Voltage range: suitable for 12 V, 24 V and 48 V DC systems — acts as a resettable 250 A fuse for overcurrent protection.
• Operating temperature: -32°C to 82°C (-26°F to 180°F). Storage temperature: -34°C to 149°C (-29°F to 300°F).
• Terminals: M10; Enclosure: IP67 waterproof; Size: 86 x 48 x 37 mm (3.39 x 1.89 x 1.46 in). Weight: 138 g (4.87 oz).
• Meets international standards S.A.E. J1625, J1171 and UL1500; ignition protected.
• Intended for surface mounting; resettable design avoids fuse replacement after fault clearing.
• Documents available to download: Time vs Rated Current graph for the Photonic Universe 250 A circuit breaker (CB250) and Temperature derating graph for the Photonic Universe 250 A circuit breaker (CB250).

Consult the time-current and temperature derating graphs to confirm installation details and any derating required for high ambient temperatures.
