JWIS Series Switch Disconnector(ISO Isolator)
ISO Isolator Electric ratings: up to 100A, 400V, AC50/60Hz;
Application: for control of motor, electric apparatus with small power, illumination, etc;.
Standard: IEC/EN 60947-3
In electrical engineering, a disconnector, disconnect switch or isolator switch (ISO Isolator)is used to ensure that an electrical circuit is completely de-energized for service or maintenance.
Such switches are often found in electrical distribution and industrial applications, where machinery must have its source of driving power removed for adjustment or repair.
High-voltage isolation switches are used in electrical substations to allow isolation of apparatus such as circuit breakers, transformers, and transmission lines, for maintenance.
The disconnector is usually not intended for normal control of the circuit, but only for safety isolation. Disconnectors can be operated either manually or automatically.
Unlike load switches and circuit breakers, disconnectors lack a mechanism for suppression of electric arcs.
Which occurs when conductors carrying high currents are electrically interrupted. Thus, they are off-loaded devices, intended to be opened.
only after the current has been interrupted by some other control device.
Safety regulations of the utility must prevent any attempt to open the disconnector while it supplies a circuit.
Standards in some countries for safety may require either local motor isolators or lockable overloads (which can be padlocked).
Disconnectors have provisions for a lockout-tag out so that inadvertent operation is not possible.
In high-voltage or complex systems, these locks may be part of a trapped key interlock system to ensure proper sequence of operation.
In some designs, the isolator switch has the additional ability to earth the isolated circuit thereby providing additional safety.
Such an arrangement would apply to circuits which interconnect power distribution systems where both ends of the circuit need to be isolated.
A switch disconnector combines the properties of the disconnector and the load switch,[1] so it provides the safety isolation function while being able to make and break nominal currents.
