This combination of three interlocked load break switches provides 3+6 or 4+8 poles for bypass applications.

2 Transfer switches svr_207_a.eps svr_208_a.eps The solution for > Manufacturing > Power distribution Function dvantages SIRCOVER 400 SIRCOVER products are manually operated transfer switches with positive break indication. There are 3 ranges in the series: SIRCOVER for open transition switching (I-0-II) available in 3 or 4 pole, SIRCOVER for overlapping contact switching (I-I+II-II), For applications where both sources are synchronised and there is to be no interruption to the load supply during transfer - available in 3 or 4 pole, SIRCOVER Bypass. This combination of three interlocked load break switches provides 3+6 or 4+8 poles for bypass applications. They provide on-load transfer between two sources for any low voltage power circuit, as well as safety isolation by double breaking per pole. Other applications include source inversion (e.g. to change the direction of a motor) or grounding/earthing. complete range There are 3 SIRCOVER models to meet every need: The standard model I-0-II, the overlapping contact model I-I+II-II and the Bypass model. Easy to connect For ratings of 2000 to 3200, we offer copper bar connection pieces. This gives you the option of different connection methods - flat, edgewise with top or bottom bridging. Stable positions SIRCOVER devices have three stable positions, unaffected by voltage fluctuations and vibrations, protecting your loads from network disturbances. On-load and isolation switching With its C-23 and C-33 characteristics, tested according to standards IEC and IEC , the SIRCOVER enables safe on-load switching for any type of load. With its on-load transfer capabilities, it is not necessary to isolate loads prior to transfer therefore the SIRCOVER offers an economical solution.

7 Copper bar connection pieces For ratings 2000 to Enables: - Flat connection: The connection pieces provide a link between the two power terminals of the same pole (Fig. 1). - Edgewise connection: The connection pieces provide a link between the two power terminals of the same pole and an edgewise bar connection terminal. - Top or bottom bridging between two poles (Fig. 3). Once installed, the power terminal is connection ready For 3200 rating, connection pieces (part ) are supplied as standard. Bolt sets must be ordered separately. Connection: The quantities given in the below table refer to the number of pieces required per pole, top or bottom. Bridging connection: The quantities given refer to the number of pieces required to complete a single bridging connection between two poles Fig. 1 Fig. 2 Fig. 3 Fig. 1 Fig. 2 Fig. 3 Connection Bridging connection Connection Bridging connection Reference Flat Edgewise I - II Flat Edgewise I - II Connection - part (2) included included included Bolt kit 35 mm - part B (1) 2 (2) 1 (1) 2 (2) Bolt kit 45 mm - part B (1) 1 (1) T + Bolt kit - part C Bracket + Bolt kit - part D Bar + Bolt kit - part E (1) Choose the bolt length according to the thickness of the bars being connected; if bar thickness is greater than 20 mm, 45 mm bolts are required. (2) For bridging connections, quantity 2 pieces are required for creating the link between the two power terminals of the same pole for switch bodies I and II. The quantities of the applicable pieces then need to be multiplied by the number of connection points (power terminals) in order to determine the total quantity required of each part. Example: For a 4 pole 2500 SIRCOVER with upstream edgewise connection (Fig. 2) and downstream bridging (Fig. 3), the following quantities will be required: Fig. 1 B (1) Single pole connection: 1 pole (top or bottom) comprises two power terminals which are to be linked with the copper connection kit.
