Product characteristics
Scope of application and use NDB1 series circuit breakers are suitable for industrial, civil construction, energy, communication and base the low-voltage terminal power distribution system in the construction and other fields has short-circuit protection, overload protection and control, isolation and other functions.
Design feature
When the circuit breaker is normally opened or tripping due to fault protection, the phase line and neutral line are broken in the On state, avoid damage caused by a neutral line fault.When the circuit breaker is switched on and off, the neutral line is switched on first and the circuit breaker is switched on,after, with overload protection and short circuit protection device, protection function is complete.Adopts "frame type" connection structure,convenient and reliable connection.TH35 standard mounting rail installation is simple and convenient.
