1 3K Load-Break Switches The Program for Safety and Performance sentric

2 Whether for reliable switching and isolation under load, or for protection against overload or short-circuits our 3K range of load-break switches cannot be beaten when it comes to safety, performance and reliability. We have versions with and without fuses, a full range of accessories, right up to special enclosures for the toughest of environments a comprehensive switch range for any eventuality. Standard for the 3KM with integrated fuses: isolating contact strip at rear for easy installation, e.g. in motor control centers (MCC) Single-pole terminal covers IP 20 from 63 A to 630 A Switchable 4th pole integrated or as accessory Fuses easily changed from IEC to BS 88 Fuse covers IP 20 Standard auxiliary switches from Siemens 3SB1 program Handle for fixed installation 8UC9 in standard (black) or EMERGENCY STOP (red) 8UC door drive mechanism with automatic tolerance adjustment ± 5 mm horizontal or vertical; standard (black) or EMERGENCY STOP (red/yellow) from switch to drive complete with non-interchangeable characteristics

3 3K load-break switches the reliable device for every eventuality 3K load-break switches are proven devices for the distribution of energy in domestic and commercial buildings as well as in applications in industrial switchboards, motor feeders or variable-speed drives. Thanks to their compact construction they can be optimally installed in any distribution system. The 3KA and 3KE switches can be used for all main, EMERGENCY STOP, maintenance, and changeover switch requirements. The 3KL and 3KM ranges with integrated fuses protect against the damaging effects of overloads and shortcircuits. They can be fitted with IEC or BS fuses, for protecting frequency converters or for fast installation on 3KM busbars. Above all, the line-side fuse always gives reliable protection from short circuits. Another advantage is that the 3K program is available complete as safety switch with high-quality 8HP insulated enclosure (IP 65) which means even more possibilities for high-performance safety concepts.

4 The 3KA and 3KE ranges of load-break switches without fuses can be used in distribution boards in residential and commercial buildings and in industrial switchboards. With 3 or 4 poles, they take care of reliable isolation and switching under load at rated current. Hence, they are ideal for all main, EMERGENCY STOP, maintenance, and changeover requirements. And they guarantee safe isolation in all low-voltage circuits. The 3KL and 3KM load-break switches with fuses also afford protection from the effects of overload and short-circuit, which makes them ideal as main and EMERGENCY STOP switches for switchboards, distribution boards and motor feeders. Equipped with Siemens SITOR semiconductor fuses, they are also capable of meeting the highest requirements, such as UPS systems, variable-speed drives or power-factor correction systems. The design of 3K means that every switch offers a double break on the contacts and thus on the isolating distance. When the switch is in the OFF position, the fuses are dead. For additional safety, each switch can be locked in the OFF position by means of a padlock at the shaft.

5 In the case of 3KM switches with fuses an isolating plug connector makes installation a simple matter without the need for tools. This is an advantage in MCCs, for example, for making the contacts with vertical busbars. The same range of accessories for 3KA, 3KL and 3KM with and without fuses saves storage space and makes spares easier to find. The two 3K ranges: Load-break switches with and without fuses For service in extreme environments, we supply the 3K special range of switches, for such applications as 63 A to 630 A safety switches in 8HP insulated housings (IP 65), and switches that are resistant to the aggressive atmospheres found in sewage treatment plants, chemical plants, or the pulp and paper industries. All 3K load-break switches are climate-proof and comply to the requirements of IEC , IEC , DIN VDE 0660 Part 107, EN , IEC , EN , DIN VDE 0660 Part 500. Advantages at a glance Complete range of switches and accessories Fuses for protection against overloads and short-circuits for optimum safety for personnel and plant, including: Fast and safe planning, shortcircuit calculations are not required (rated short-circuit capability up to 120 ka) No discrimination limits to upstream fuses High AC23 switching ratings at 690 V without reduction of the technical data Cost-saving installation on 60 mm busbar systems in MCCs Complete program of safety switches in high-quality 8HP insulated enclosures (IP 65) Optimum protection of frequency converters in combination with SITOR semiconductor fuses Special version for resistance against aggressive atmospheres, for installation in the pulp and paper industries, chemical plants and mining
