Series Overview
Series Overview
- The new 3KD isolating switch can provide reliable protection for buildings, infrastructure, industrial plants, and personnel, ensuring high system availability. By using this isolating switch, customers can implement projects more efficiently and maintain long - term competitiveness.
Avoid Electrical Accidents
- Using the 3KD isolating switch can systematically avoid electrical accidents. For example, during the maintenance of machinery and equipment, unauthorized operations can be prevented through the corresponding locking function. The terminal cover of the 3KD isolating switch can enhance touch protection and prevent electric shock. The 3KD isolating switch adopts a transparent contact cover, so that the contact position can be clearly seen at any time.
Improve Work Efficiency
- The installation of the 3KD isolating switch is fast and convenient. Because it has a modular design and provides a variety of accessories, it can be modified at any time to add functions. Convenient ordering and fast delivery also help optimize inventory. Therefore, you will not only benefit from shortened time and reduced costs, but also greatly improve work efficiency in the planning stage, because you will obtain CAx data related to the entire engineering 组态 process.
Increase Flexibility
- The application of the 3KD isolating switch is very extensive, which can meet all your needs. It can be used as a main control switch, as well as an emergency or maintenance switch. It has a variety of connection methods and multiple operating mechanisms, and provides rich accessories.
- The 3KD isolating switch can be used as a maintenance switch in the factory to perform safe maintenance operations in a voltage - free state.
- The 3KD isolating switch can be used as an emergency switch in the factory to provide protection for operators.
- The 3KD isolating switch can be used as the main control switch in the low - voltage distribution system to isolate from the power supply system.
Product Highlights
- Compact structure, optimizing the space of the main distribution cabinet, control cabinet or distribution cabinet.
- The 3KD1 to 5 have a modular structure, which can quickly and conveniently retrofit N or N/PE terminals or the 4th contact element as an additional stage.
- The 3KD1 to 5 have a variety of operating mechanism designs and are widely used: side operating mechanism or front operating mechanism. The side operating mechanism is located on the right side of the switch, and the front operating mechanism is located in the center of the switch or on the left side of the switch.
- The 3KD1 to 5 can perform functional tests on the control circuit through the auxiliary contact test function.
- The locking function can provide high protection for personnel and equipment (even in limited installation space).
- When the current is below 160A, it can be quickly installed on the standard installation rail.
Applications
- The 3KD isolating switch is designed for applications with strict requirements. It can be used as the main control switch, emergency stop switch or maintenance switch in factories, infrastructure and key buildings. The 3KD isolating switch can be turned on or off with load at the corresponding rated current. Its isolation function can provide a safe isolation distance for low - voltage circuits.
- All 3KD isolating switches are of the air - tight type, complying with standards IEC 60947 - 1, IEC 60947 - 3 and VDE 0660 - 107.
Features
- 3 - pole and 4 - pole types, 7 specifications
- Provide complete sets (including direct operating mechanisms), and also provide basic units without handles
- Provide complete sets of isolating switches with direct operating mechanisms
- Provide isolating switches with door - coupling rotary operating mechanisms for external cabinet operations
- Provide isolating switches with side operating mechanisms
- The 3KD1 to 5 have different wiring methods such as box - type terminals or flat connections
- Surface installation or standard rail installation (specifications 01/02 and specification 1/2)
- Can be retrofitted with additional stages: 4th contact element, N or N/PE terminals
- Auxiliary contacts for switch position monitoring
- Applicable to both AC and DC applications
- Enhanced touch protection
- The contact positions of 3KD1 to 5 are clearly visible
- The locking function helps prevent unauthorized operations
- Enhanced phase - to - phase electric shock protection
- Compact design, saving space
- With various operating mechanism designs, widely used
- The 3KD1 to 5 have a modular design, easy to install
- Optimized heat dissipation, suitable for various working positions
- The 3KD1 to 5 have a test function to ensure safe testing
- Provide comprehensive support through CAx data
Design
- The 3KD isolating switch includes an operating mechanism module, three or four breaking poles, and an isolating switch operating handle.
Handle
- The handle of the direct operating mechanism type is directly installed on the isolating switch. The handle can also be provided in the form of a door - coupling rotary operating mechanism for operating the isolating switch outside the control cabinet.
- The color of the handle is gray, or red/yellow for emergency stop switches. Common switches including basic units and handles can be provided in the form of complete sets.
