High quality materials for the best protection
Switch disconnectors must meet certain requirements to be used in electrical installations. Therefore, it is important that they are made of high-quality materials. The material that resists electronic charging is ABS plastic. ABS (acrylonitrile-butadiene-styrene copolymer) is an engineering plastic that is particularly suitable for switch disconnectors. The material is not only resistant to mechanical stress, but also to grease and oil. Good temperature resistance and resistance to household acids are also criteria that plastics meet, making them ideal materials for switch disconnectors. In combination with other strong and high-quality materials, the switch is extremely durable.
Where are load break switches used?
Load break switches are mainly used as main switches and changeover switches in small medium voltage distribution systems. They are also used to open and close ring circuits. Switch disconnectors are also used to switch transformers under load and unloaded, cables and overhead lines, and capacitors for reactive current compensation. Switch-disconnectors are also used in place of disconnectors to improve the safety of switchgear. In combination with built-in high-capacity fuses, they can be used in networks with higher short-circuit values. In low-voltage networks, disconnectors are used to break the main circuit in the main distribution area.
Difference between switch disconnector and circuit breaker
The functions of load break switches and circuit breakers are combined in the high quality load break switches. Load switches are switches that can only be used in the low and medium voltage range. Among other things, this includes the simple switching on and off of light. Load break switches are usually operated manually. Motors cannot be switched because the inrush current is too high. Circuit breakers, on the other hand, are high-voltage switches. As the name implies, a circuit breaker achieves significantly more power than a switch disconnector. They are also capable of switching on higher currents in the event of a fault, stopping them for a certain time and then switching them off again safely. These include high overload currents as well as short-circuit currents. The biggest difference, then, is the amount of current that a switch-disconnector and a circuit breaker can easily switch. Furthermore, unlike the load-break switch, the circuit-breaker uses an electric drive in addition to the manual drive.
