Product Description

Professional Manufacturer Plug-in Type STH2 Series Miniature Circuit Breaker 10KA 1P 2P 3P 4P 15A-30A 40A-60A 120/240V Electrical MCB with Competitive Price


General

     STH2 Series plug-in type miniature circuit breaker is for overload & short circuit protection which used in residential and industrial distribution system. With the following characteristics: Copper stabs, tin-plated for corrosion resistance, make the connection reliable and permanent; Heat-resistant thermoset cases and covers add stability and structural rigidity; Trip are easy to spot because handles trip to the center position; The dedicated calibration screw is cemented(not simply papered over) to prevent shifting, the result is stable calibration for optimum trip performance. It is mainly used in the line of 50/60Hz, rated working voltage to 120V/240V, and rated current to 60A. And it complies with the standard of IEC60898-1.

Selection
    ·Technical data of the network at the point considered: short-circuit current at the circuit-breaker installation point, which must always be              less than the breaking capacity of this device, etwork 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.
       D curve(10-14In)   protection for circuits which supply loads with high inrush 
                               current at the circuit closing (LV/LV transformers, breakdown lamps).
