Functions

Disconnection of a three-phase circuit – disconnects 3 phases simultaneously in a three-phase electrical system
Load isolation – allows the electrical circuit to be safely separated from the power supply during maintenance or repair
Manual switching on and off – the switch is operated mechanically, allowing clear control of the circuit status
Use in electrical panels – designed for installation in electrical distribution or control cabinets
Main disconnector function – can be used as the main manual disconnection point for a specific circuit or device
Increased service safety – helps reduce risks during electrical equipment maintenance
Power control of industrial equipment – suitable for disconnecting three-phase motors, equipment, lines or distribution circuits
Clear contact position – the knife-switch construction makes it easier to understand whether the circuit is switched on or disconnected
Operation in 50/60Hz networks – can be used in different alternating current networks
Suitable for AC420/690V systems – designed for three-phase industrial alternating current circuits

Use

For household users: Can be relevant in garages, workshops or utility buildings where three-phase equipment is used and manual circuit disconnection is required.
For electricians: Suitable for installing electrical panels where a clear 3-phase load disconnection point is required.
For engineers / designers: Can be included in electrical distribution diagrams as a manual load isolation switch.
For industrial companies: Used for disconnecting production lines, three-phase equipment, motors or electrical distribution circuits.
For maintenance specialists: Helps safely disconnect equipment before repair, inspection or service work.

Advantages

100A rated current – suitable for higher-power three-phase circuits
3P construction – all three phases are disconnected simultaneously
Suitable for AC420/690V systems – can be used in industrial three-phase systems
Clear mechanical control – easy to understand the switch status
Suitable for installation in electrical panels – designed for distribution and control cabinets
Convenient for maintenance – allows safe circuit disconnection during service work
Universal application – can be used in industry, commercial facilities, workshops and technical rooms

Disadvantages

No automatic protection function – this is not an automatic circuit breaker with short-circuit or overload protection
Manual control – no remote or automatic switching function

Is this switch suitable for a three-phase system?

Yes. The switch is 3P, therefore it is designed for three-phase electrical circuits where three phases need to be disconnected simultaneously.

Can it be used as the main disconnector of an electrical panel?

Yes, it can be used as the main manual disconnector, but the specific electrical installation diagram, load, protection devices and applicable requirements must be assessed.

Does this switch protect against overload?

No, the switch does not replace a circuit breaker or fuses. Dedicated protection devices must be used for overload and short-circuit protection.

Where is this switch installed?

It is installed inside an electrical panel, distribution cabinet or control cabinet for disconnecting a three-phase circuit.
