2 02 03 Introduction Integrating end user convenience with installation flexibility C&S offers Switch Disconnector Fuse units from 32 to 800 ratings, 3 Pole as well as 4 Pole. These have C23 utilisation category as per IEC 6094 / IS They are available with DIN as well as BS type fuse holder & suitable for operations upto 690V. They have been tested in independent & internationally acclaimed laboratories of ST for compliance to IEC standards, and at CPRI & ERD for conformity to IS standards. Modular yet rugged construction of the Switch Disconnector Fuse units gives dd On pole flexibility while maintaining absolute reliability and 100% rating as the main poles. This arrangement is suitable for 3 Phase 3 Wire, 3 Phase 4 Wire as well as any type of Earthing and even for DC installation. The mounting flexibility offers matchless benefit for use in MCC / PCC distribution boards or for standalone mountings. It is compact enough to occupy small panel space yet allowing installation as per convenience and rendering it safe for maintenance. Multiple accessories to suit application requirements enhance flexibility of operation and the safety level of installation. It also ensures use in diverse applications. The entire range of Switch Disconnector Fuse unit integrates enduser convenience with features suiting OEMs & Switchboard builder requirements. For over 15 years now, with their rugged design combined with ease of operation and maintenance, they have stood the test of adverse environments in all climate of various countries. They have been used successfully in almost every industry, becoming the exclusive choice of every discerning user, be it Power Plants, Building segments, Telecommunication field or Industries like Steel, Chemical, Cement, utomobile, etc.

04 05 Modular and user friendly Internationally Endorsed Tested & ccepted World over Easy Installation Convenient, Swift & Economical C&S Switch Disconnector Fuse units have been tested for their

IS 13943. These also conform to the safety regulations adopted in the European Union and carry the CE marking.

ISO 9001 certified manufacturing facilities assure quality & consistency.

The flexibility of design lets the spring operating mechanism also to be placed in the side or in between the Poles.

nd each additional Pole retains the same reliability and 100% rating as the main phase Pole.

Efficient Switching & ong life Switch Disconnector Fuse units of rating 200 and above employ unique Knife Contact Mechanism on both sides of the fuse.

When current increases, the contact force too increase, ensuring good contacts at all times, high making and breaking capacity upto 690V and low temperature rise leading to long electrical life.

3 04 05 Modular and user friendly Internationally Endorsed Tested & ccepted World over Easy Installation Convenient, Swift & Economical C&S Switch Disconnector Fuse units have been tested for their conformity to International as well as Indian Standards at various independent aboratories likest for conformity to International StandardsIEC and CPRI, ERD for conformity to Indian Standards IS These also conform to the safety regulations adopted in the European Union and carry the CE marking. OEMs and panel assemblers can be reassured that the design and quality is being used and exported to many countries world over. ISO 9001 certified manufacturing facilities assure quality & consistency. Flexible Design Unique Contact Mechanism Modular yet reliable construction C&S Switch Disconnector Units have a modular assembly design, allowing 1 Pole to a 4 Pole combination. The flexibility of design lets the spring operating mechanism also to be placed in the side or in between the Poles. Thus all possible combination like the TP / TP + Isolable Neutral / Four Pole in 2 options Switched Neutral or Fused Neutral are obtainable. nd each additional Pole retains the same reliability and 100% rating as the main phase Pole. s each Pole is independent of the other, its maintenance or replacement is easy and economical in the event of damage. Efficient Switching & ong life Switch Disconnector Fuse units of rating 200 and above employ unique Knife Contact Mechanism on both sides of the fuse. It uses the magnetic attraction principle in iron circuit on the moving contacts. When current increases, the contact force too increase, ensuring good contacts at all times, high making and breaking capacity upto 690V and low temperature rise leading to long electrical life. The special form of fixed contacts alongwith rc Chute fins blows away the arc in the rcchute where it is swiftly extinguished under controlled conditions making it safer. With every switching, the knife contacts clean themselves. This makes them perfectly suited for applications like Motors and capacitor switching. ll these qualities makes them ideally suited for Indian conditions in general and for high pollution and corrosive conditions as in Chemical Plants, Cement Plants, Steel Plants, etc. The handle in the C&S switch disconnector fuse unit has a telescopic shaft. The handle & shaft assembly adjusts to wide depth of the panel so there is no need to place a bracket below the switch while aligning it with enclosure door. It permits installation of the same switch in installations of different depths, without any modification or addition to the enclosures. Four hole handle fixing on the door permits last minute rotation of the switch inside the panel by 90 degrees or 180 degrees as per convenience, again without any modification to the door. These time saving features increase the ease and flexibility of installation, and also reduce installation cost. ccessories Flexibility to suit pplication These units came with a multiple accessories to increase their suitability for diverse application, to enhance operational flexibility and to improve installation safety. Handle mounting kit permits fixing complete Switch Disconnector unit inside the enclosure door so that switch can be operated only after opening the door. uxiliary contacts permit electrical interlocking, remote indication and larm. Key ock and Castle ock help interlocking with different category of products. Extended terminals allow further liberal termination or termination of large number of cables with higher clearances. Shrouds encase the terminals so that no falling hardware may get embedded between the terminals resulting in flashovers. Switch Construction Safety Builtin C&S design introduced the concept of protection in case of welded contacts. In the event of high current and fuse fails to operate, this leads to welding of contacts. In C&S switches, the handle will not turn beyond 45 degrees from the ON position, which clearly indicates that the supply is ON and contacts get welded. In OFF position, the fuse is discharged from both sides, permitting safe inspection or removal.. The individual pole is housed in fibreglass reinforced insulating material that is selfextinguishing and can withstand high temperatures. The high tracking index makes these switches almost flashover proof and highly safe. Door interlocking prevents it s opening in the ON position, guarding the operator against an accidental mishap. s a standard upto 3 padlocks are provided in the OFF position to prevent closing the circuit during maintenance work. They can also be provided for the ON position. Using a suitable gasket alongwith handle enhances ingress protection level to IP 65.
