CHINT 12v circuit breaker

There are various types of CHINT circuit breakers suitable for 12V circuits. The following are some common product series and their features:

- **NB1-63DC series**: It belongs to small DC circuit breakers. Different pole numbers such as 1P and 2P are available for selection. It is applicable to various DC voltages such as 12V, 24V, and 250V, and the rated current ranges from 1A to 63A. It can be used in scenarios such as photovoltaic (solar energy) systems. It has functions such as overload protection and short-circuit protection, and can quickly interrupt the fault current to protect the safety of the circuit.

- **NB1Z-63 series**: It is also a circuit breaker used in DC circuits. It has a 2P specification and is applicable to DC voltages of 12V, 24V, and 220V. The rated currents include 20A, 32A, 40A, etc. It can be applied to photovoltaic systems and can provide reliable protection for DC circuits.

When selecting a CHINT 12V circuit breaker, it is necessary to determine the appropriate model and specification according to specific circuit parameters (such as rated current, load type, etc.), application scenarios, and protection requirements. 

The price of CHINT 12V circuit breakers varies depending on factors such as specific models, specifications, sales channels, and the quantity purchased. The following are some price references for common models:
