Page 5: Introduction
Page 5/25 Rev.1.1 User Manual, Power contactors, series CT1115/04 and CT1130/04 CT1000 contactors are air switching components with arc breaking in ce- Introduction ramic. They use a highly sophisticated principle of arc control, combining the permanent-magnetic and electro-magnetic blow-out technique. This allows practically unrestricted operation for all AC and DC voltages and currents within the technical specification. -

Page 12: Storage
Schaltbau recommends storing the contactors in the original packing box. Storage The contactors should be stored in a dry and suitable place. Schaltbau recommends using the original packing box for any return ship- Return shipments ments. If no original packing box is available care should be taken to pack the contactor in a way that prevents damage during the shipment. -
Page 13: Operating Position
The contactors (Lower Module) are fixed with 4 or more mounting screws, depending on the number of poles. The screws (and if applicable the nuts) must be steel grade 8.8. Schaltbau strongly recommends Schnorr-Washers (or similar) to secure the screws. The screws must be tightened with the rat- ed torque permissible for the screws and the nuts. -
Page 14: Electrical Requirements
Clean the surface of the mounting plate and the base-plate of the contactor Mechanical installation (Lower Module). Put the Lower Module on the mounting plate and secure with the appropri- ate screws using the correct tightening torque. Schaltbau strongly recom- mend Schnorr-Washers (or similar) to secure the screws. -
Page 15: Electrical Installation Of The Auxiliary Switches
Page 15/25 Rev.1.1 User Manual, Power contactors, series CT1115/04 and CT1130/04 Connect the wires for the auxiliary contacts. For the a1 and b0 contacts Electrical installation of (Switches S870) no polarity must be observed. For the general purpose the auxiliary switches contacts (Snap action switches S826) the polarity must be observed. -
Page 16: Mounting Of The Upper Module
The screws must be tightened with the rated torque (re- fer to label on the Upper Module). If you want to use current bars as recommended by Schaltbau, it is better to mount the bars below the main terminal. This way maintenance is much easier and the upper module can be removed without removing the current bars. -
Page 17: Electrical Installation Of The Earth Terminal
The use of press nuts in the current bars will simplify installa- tion and maintenance. Connect the earthing cable to the earth terminal with the appropriate screw. Electrical installation of Schaltbau strongly recommends a Schnorr-Washer (or similar) to secure the the earth terminal screw. Commissioning... -
Page 18: Maintenance
Page 18/25 Rev.1.1 User Manual, Power contactors, series CT1115/04 and CT1130/04 CT1000 contactors are maintenance-free within the rated mechanical Maintenance life time. The electrical life time depends on the number of switchings under heavy load conditions and may vary for different applications. In normal use, this corresponds to a decade-long operating period. -
Page 19: Spare Parts, Replacement Of Parts
However, in case of permanent heavy load switchings, of failures, of short- circuit switchings or in similar cases spare parts are offered by Schaltbau. Only original spare parts are to be used as a replacement MC CT1015/04... - Page 20 Page 20/25 Rev.1.1 User Manual, Power contactors, series CT1115/04 and CT1130/04 Remove and replace the fixed contacts (and ceramic protection insert) Put the Upper Module onto the table upside down on a smooth surface. The latching levers must be in the closed position to avoid damage Remove all four M5 screws with a number 8 socket wrench and put the screws and washers aside.
- Page 21 Page 21/25 Rev.1.1 User Manual, Power contactors, series CT1115/04 and CT1130/04 The following steps concerning the ceramic protection insert are for CT1030/04 only. The ceramic protection insert is fixed with glue. It Cut the glue carefully with a knife and pry it has to be replaced only in case of apparent wear open.
