Modular DIN Rail NBH8 Miniature Circuit Breaker

1.1 Function

protection of circuits against short-circuit currents,protection of circuits against overload currents,switch,isolation.

1.2 Selection

Technical data of the network at the point considered:the earthing systems (TNS, TNC),

short-circuit current at the circuit-breaker installation point,  which must always be less than the breaking capacity of this device,network normal voltage.

Tripping curves:

B curve (3-5In) 

protection for people and big length cables in TN and IT  systems. 

C curve (5-10In)

protection for resistive and inductive loads with low inrush current.

100% Factory Tested Prior to Shipment

All our control cabinets are fully tested before they leave our factory. This includes applying power and testing all the branch circuits and testing all I/O points to their terminal blocks. We read inputs back through the PLC and force outputs from the processor to ensure proper operation. Any additional operator controls such as Hand-Off-Auto switches and motor starters are also completely tested.
