6 Changeover Switches C-Line offers you a unique series of changeover Switches combining compactness with high performance & Customer convenience, thus, making C-line a state-of-the-art product in changeover technology. The C-line range covers ratings from 6 A to 000 A in 6 frame sizes. These changeover switches are available in open execution, Sheet steel enclosure, fused version (suitable for DIN type fuse - link) and motorised version. SS Enclosure inclusive of cable gland box Field-convertible fuse changeover switch Motorised changeover switch Basic function of Changeover Switches Onload Changeover S-D has stable positions as defined below POSITION l Switch is in ON position with normal supply available at the outgoing terminals. POSITION O Switch is in OFF position and outgoing terminals are isolated from both supplies (normal and alternate supplies) POSITION ll Switch is in ON position with alternate supply available at the outgoing terminals. Onload Changeover S-D consists of two separate sets of terminals for incoming supplies and a set of output terminals to connect the common load. Thus, changeover switch ensures continuity of supply to the load by alternating between normal and alternate supply.

7 Superior Performance Higher short-time withstand Capacity Contact system is of double break, knife type having self wiping action with electrodynamic compensation. This ensures reliable performance during normal as well as short circuit fault conditions, offering higher short-time withstand rating. Higher life C-line switch offers high electrical and mechanical life in compact frame sizes. The electrical and mechanical life are two times the requirement of the standard. Total flexibility of connection Factory fitted external shorting links can be easily removed and fitted on the other side as required at site (15 A to 000 A). This gives more flexibility at the time of installation. Maximum termination capacity The C-line range provides generous terminal capacity in its compact size, facilitating aluminium termination. Higher ground clearance Higher ground clearance between terminals and mounting base plate ensures adequate clearance even after connecting cables. This eliminates the possibility of phase to ground flash over. Total safety C-line Changeover Switch provides complete safety by providing terminal shrouds, source separator and inter-phase barriers. 4
