Raytel MCBs
Raytel Controlgear Supplies Ltd has announced a new range of MCBs from HPL in India. The range
comprises B, C and D type breakers in 1, 2 and 3 pole versions at 10kA breaking capacity all with mid
trip position for clear indication of the faulty circuit.
The high speed Current Limiting action ensures the MCB operates before the full prospective fault current is allowed to develop. Under fault conditions, damage can be sustained to the installation and associated equipment due to the amount of energy that passes before the current is completely interrupted. The total energy let through depends upon the value of current and the time for which it flows. The high-speed current limiting action of TECHNO MCB ensures the energy let through and any subsequent damage is minimised.
This reduced Let Through Energy (Class 3 as per BS EN 60898) assist greatly with both back up and
discrimination considerations. TECHNO MCBs have also been designed to minimise energy loss through its contact configuration and reduction of hot spots and watt loss per pole is far lower than that specified in
IEC898-95.
