MCB TPN

 

Ø  reinforced polyester. The housing can withstand high temperature and is impact resistant.

Ø  OPERATING MECHANISM : The operating mechanism is so designed as to make it completely safe and dependable. Glass fibre reinforced body of MCB,s is self lubricating to eliminate wear and tear and corrosion. The MCB’s components being light in weight have low inertia thereby ensuring snap make and break. The reliability and ruggedness of the operating mechanism is thus maintained.

Ø  ARE EXTINGUISHING CHAMBER: MCB consists of a specially designed 12 plates arc chamber for achieving quicker extinguishing of the Arc generated during short circuit up to 10000 Amps.

Ø  CONTACTS : Contacts are made of silver plating.This provided definite advantages to MCB. Such as low contact resistance reduced voltage drop and reduction in power loss.

Ø  MOUNTING ARRANGEMENT : MCB’s can be installed on Standard (35mm) DIN Bars by a simple snap action.

Ø  TERMINAL : 25mm2 (box type terminal)

Ø  MECHANICAL INTERLOCKING OF MULTIPOLE MCB’S: The tripping mechanism of all multipole MCB’s is connected internally. This ensures simultaneous tripping of all poles even if the fault occurs in any one of the phases thus preventing single phasing.
