CLR Breaker

CLR breakers from Samrakshana Electricals Ltd provide short circuit and thermal protection for both pad mounted and overhead distribution transformers. The breaker is immersed in the transformer oil on the low voltage side to protect the transformer against secondary faults or excessive overloads. CLR breaker has been designed to minimise the electrical losses incurred in the breaker. This breaker is designed using state-of-the-art bimetals, which provide reliable accurate performance with minimum losses. Single contact (one per pole) of the breaker is comprised of 65 percent tungsten, 35 percent copper, and is silver-plated. This provides a low resistance conductor, without sacrificing the ability of the contacts to perform multiple make and break operations under short circuit conditions. These breakers are available with a combination of both braided an strap type leads, thus providing high flexibility yet low total resistance resulting in minimum losses for any given lead length. The CLR"s short circuit capacity of 5,000 symmetrical amperes at a maximum of 350 volts per pole provides sufficient interruption rating for a worst case fault. Features: Low losses Rugged construction Flexibility in mounting Short circuit capacity Reliability Signal light circuit Emergency control Optional features Signal light circuit - This operates at 25?C below the breaker trip temperature and functions as an inexpensive load study tool warning of potential overloads. Emergency control: The emergency control feature increases the breaker trip temperature to 20?C above its original level. This prevents the breaker from tripping in the event of sustained moderate overloads. When this feature is activated, it severely limits the breaker"s thermal protection.
