Protection Unlimited

Electricity is an inseparable part of our daily lifestyle. In residential, commercial and industrial sectors there are myriad systems, equipments and sophisticated appliances that depend on electrical energy. Uncontrolled electrical power can be extremely dangerous. Overloads, crowded wiring, short-circuits and all kinds of interruptions in electric supply can lead to devastating losses, least of them being financial. We at STANDARD are proud to be known and respected the world over 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 from STANDARD is 10kA MCB, is an advance Indian design of high performance, current limiting and automatic switching for control and protection of industrial, commercial & domestic electrical sub circuits. It meets the latest specification IS : 8828 & IEC : 60898-1 of B & C Characteristics. The primary function of the MCB is to protect the installation such as cable & other components from damage, resulting due to overload & short-circuit fault. Under overload heating effect can occur on cable. Protection in this respect is assured by matching the cable rating to the current rating of MCB. Under short-circuit condition, mechanical damage can occur due to strong magnetic field caused by high current peaks and overheating of cables on account of "exclusive let through energy". The current limiting action of " MCB" ensures low value of both peak current "cut off" and minimum let through energy. STANDARD MCBs protect against overload and short circuit. a) Overload Protection It is achieved by thermal operation of the bimetal strip which deflects when heated by the over current going 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-efficient of thermal expansion which are permanently bonded together by pressure welding. b) Short Circuit Protection In 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.

Features & Benefits

DESIGN Latest & one of the best designed MCB. HIGHER PERFORMANCE IN A SMALLER PACKAGE ­ MCBs conforms to the latest Standards IS 8828 & IEC 60898-1 with 10kA breaking capacity. ­ These MCBs provide reliable protection to circuits against overload & short-circuit ideal for industrial, commercial & residential installations. CERTIFICATIONS SHOCK PROOF Offer IP 20 degree protection. All live parts are out of human reach ensuring safety to installers. LONGER LIFE Reduced electro magnetic stresses resulting in increased contact life. FLEXIBILITY Can be mounted easily in any of the regular Distribution Boards. ENERGY SAVING IS : 8828 & IEC 60898-1 have recognized the growing importance of limiting power loss in Switchgear devices and stipulated max. permissible power loss values per pole of MCB. MCB having power loss figures of 50% lower watts than IS requirement. Thus, 50% energy & cost saving by application.

3. Standard MCBs are available in 3 versions : 1. `B' Type MCBs

Time Current Characteristic Curves

These are suitable for installations having resistive load like Heaters, Ovens, GLS Lamps etc. The magnetic trip system operate between 3In to 5 In. 2. `C' Type MCBs These are suitable for installations with high inrush of current at the time of switching i.e. having inductive loads such as motors, airconditioners, transformers, halogen/ fluorescent lamps etc. The magnetic trip system operate between 5 In to 10 In. `D' Type MCBs These are suitable for protection of electrical circuits which causes high inrush current, typically 12-15 times the thermal rated current (transformers, X-ray machines etc.) Short circuit release is set to (10 - 20) In. Note : B, C & D type MCBs have same overload tripping characteristics.

HIGHER BREAKING CAPACITY Breaking capacity of 10kA for the complete range from 0.5A to 63A in single pole and multipole tested at CPRI. LARGER TERMINALS Dual termination facility for incoming side and can take wire upto 25sq. mm cross section. Wire may be of copper or aluminum.

Current Limiting Design

In a current limiting breaker, the tripping & arc control mechanism is so designed that under short circuit conditions, the contacts are physically separated and the electrodynamic forces set up by fault current assist the extinction in less than half cycle. The figure shows the current limiting effect of a circuit breakers. Fault Traces for Voltage & Current 0 = Point of fault initiation tx t1 t2 = Contact opening time (i.e., creation of arc) = Current / Voltage peak (i.e., current limitation) = Time to total extinction of arc (i.e., complete shutdown of fault current)
