Here are the key specifications for the CHINT “NB1-63DC” series miniature circuit breaker (MCB) suitable for DC applications in 2-pole (2P) and 4-pole (4P) configurations:
✅ Typical Specifications
-
Rated current (In): 1 A, 2 A, 3 A, 4 A, 6 A, 10 A, 13 A, 16 A, 20 A, 25 A, 32 A, 40 A, 50 A, 63 A. Chint Global+2chint-circuit-breaker.com+2
-
Number of poles available: 1P, 2P, 4P. chint-circuit-breaker.com+1
-
Rated voltage (Ue) for DC: up to 1000 V DC in the 4P version. BaoAnJSC+1
-
Breaking capacity (Icu) for DC: typically 6 kA for DC versions cited. BaoAnJSC+2BaoAnJSC+2
-
Tripping curve: often “C type” (≈ 7-10 × In) for the DC version. chint-circuit-breaker.com+1
-
Ambient and installation conditions:
-
Ambient temperature: –35 °C to +70 °C. chint-circuit-breaker.com
-
Pollution degree II. chint-circuit-breaker.com
-
Altitude ≤ 2000 m typical (higher altitudes require checking derating). chint-circuit-breaker.com
-
-
Standards / compliance: IEC/EN 60947-2 (for DC MCB) plus RoHS.Mounting / connection: DIN-rail style, screw terminals (depending on variant). BaoAnJSC+1
-
2P (2 pole) version can typically handle a DC rated voltage like 500 V DC (as shown in some product listings). For example: 2P C16A, 500 V DC, 6 kA. BaoAnJSC
-
4P (4 pole) version allows for higher voltage DC ratings (e.g., 1000 V DC) by combining poles, useful for higher-voltage DC systems (string solar, battery storage) in applications requiring dual pole + two additional poles for balancing/series. For example: 4P C40A, 1000 V DC, 6 kA
