We at GreatWhite are proud to be known and respected for our range of superior quality electrical control and safety devices. Through these, we speak of our lasting concern for safety, economy and productivity for our customers.

The latest product of GreatWhite is the 10kA MCB which is an advance International design for high performance, current limiting and automatic switching to ensure complete control and protection of industrial, commercial & domestic electrical sub circuits. It meets the latest specifications of IS/IEC: 60898-1.

GreatWhite MCB’s ensure the safety of cables and other electronic peripherals with a dual protection system that safeguards against thermal overload and electromagnetic short circuit. Manufactured using quality components, like Silver Inlaid Copper, maximise contact reliability and provide increased energy savings. Housed in a high strength, flame retardant material with shock proofing and snap push technology improves safety and ease during mounting and demounting without interfering with other MCB’s within the distribution board. Designed to surpass the highest international standards with a massive 10KA breaking capacity for the full range of 0.5A to 63A and a unique mid trip feature that allows instant identification of faulty circuits.

This is achieved by thermal operation of the bimetal strip which deflects when heated by the over current passing through it, thereby tripping the operating mechanism and causing the contact to open.

THERMOSTATIC BI-METAL
It is a composite material comprising of two metallic layers of different co-efficients of thermal expansion. These are permanently bonded together by pressure welding.

SHORT CIRCUIT PROTECTION
In an event of short circuit, the high current - in the range of kA, energises the solenoid and a magnetic field is created. Due to this magnetic field, the anchor is pulled down which pushes the plunger to strike the inner latch causing instantaneous opening of the contacts.

The flow of current through electrical facilities always involves risks. Poorly insulated equipment, faulty wires and incorrect use of electrical devices cause current to flow through the wrong path (i.e. through the insulation) to the earth. This current is called ‘Leakage Current’. Earth leakage is an electrical hazard and is responsible for electrical shocks and fires. Earth leakage and its associated hazards can be prevented by Residual Current Circuit Breaker (RCCB) that is also popularly known as Earth Leakage Circuit Breaker (ELCB).

Greatwhite Isolators are switch disconnectors with independent manual operation, capable of making, carrying, and breaking current under normal circuit conditions, which may include operating under overload condition and also carry current under a specified abnormal circuit conditions such as those of short circuits for a specified time.

• Safety terminals to avoid improper cable termination
• Easy Snap pusher for mounting easily on Din Rail channel of DB’s
• Large cable terminal to terminate cable size upto 25 sqmm
• Cooler operation - Grooves provides on outer body on Isolator so that when individual poles are placed adjacent to each other in DB’s It forms a very infective path for better air circulation resulting no overheating between two poles.

GreatWhite MCB Changeover Switch is a manual operated changeover switch for switching load between two power supplies. MCB Changeover switch finds wide applications in residential, commercial as well as in industries area. This switching device widely accepted For Individual Bungalow (IB) which is having low voltage distribution circuits. Changeover switches are used to shift from one source of supply to another source and vice versa. GreatWhite MCB changeover switch comes in 2P (Double Pole) and 4P (Four Pole) versions, for single and three phase application respectively. It has three positions ( I-O-II) with centre-off. They are switch disconnectors with independent manual operation, capable of making, carrying and breaking currents under normal circuit conditions. Which may include operating overload condition and carry under specified abnormal circuit conditions such as those of short circuit for a specified time.
