Product Description

NBSe NBSK1-125 2P 40A Isolation Switch,Main Switch

 

 

Features

 

High-current instantaneous tripping function: When the circuit breaker is closed or during operation, if short-circuit high current (> 20 [nm) is encountered, the magnetic tripping mechanism of the circuit breaker can be tripped directly, and the double protection is more reliable and safe;
With trip test (test) function: input DC DC12V voltage test circuit breaker action characteristics;
Fault self-diagnosis function: protect and check the working status and running quiet condition of the intelligent controller itself;
High protection tip: overload protection, short-circuit short-delay protection action time accuracy t 10%; short-circuit instantaneous protection action value tip is 15% depending on the action current:

 

Description:

 

1. Thermosetting material shell, high stability of Mechanical property and size, Excellent corrosion resistance, and Heat resistance and arc resitance, Excellent performance
2. Double contact design, Reliable action
3. optimal design for contact system and trip mechanism
4. Spring energy storage design to
5. din rail mounting,easily be used with Modular electrical devices
