Modular switch disconnector | 3P | 40A | 415V | DIN | Schneider Electric | iSW | A9S65340

Technical specifications

Manufacturer: Schneider Electric
Product type: modular disconnector / isolating switch
Number of poles: 3P
Rated current: 40A
Rated voltage: 415V AC
Mounting: on DIN rail
Use: for switching on, disconnecting and isolating electrical circuits
Suitable network: for three-phase electrical circuits
Purpose: for distribution boards, automation cabinets, industrial and commercial installations

Functions

Three-phase circuit disconnection – a 3-pole electrical circuit can be disconnected with one action
Manual switching on and off – allows convenient control of the electrical circuit in the distribution board
Circuit isolation for technical maintenance – suitable for use when equipment needs to be safely disconnected from the power supply before carrying out work
DIN rail mounting – fast and standardised installation in electrical panels
40A load control – suitable for medium-power three-phase electrical circuits
Compact modular solution – takes up little space in the electrical panel and can be easily combined with other modular equipment
Clear mechanical position – the switch position allows visual indication of whether the circuit is switched on or disconnected

Use

For household users: Can be used in the electrical panel of a house, garage or utility premises when it is necessary to control a three-phase electrical line. For example, it may be relevant for three-phase equipment, heating systems, workshop equipment or separate electrical zones.

For electricians: A solution for installing new distribution boards or modernising existing installations. DIN mounting allows the disconnector to be quickly integrated together with circuit breakers, residual current relays, surge protection devices or other modular equipment.

For engineers / designers: When designing electrical distribution systems, a 3P 40A modular disconnector can be specified as a manual disconnection point for three-phase circuits. It is relevant where clear isolation of the electrical circuit is required for technical maintenance or system control.

For industrial and commercial premises users: Suitable for workshops, warehouses, production areas, technical rooms and commercial facilities where three-phase electrical equipment is used. The disconnector allows the selected circuit to be conveniently disconnected without dismantling the entire electrical system.

Advantages

Clear manual control
Suitable for distribution boards
Used in households, commercial facilities and industry
Convenient solution for circuit isolation during technical maintenance

Disadvantages

Does not perform the function of residual current protection
Not suitable for use as the only protection if the circuit requires automatic protection

Does this disconnector protect against short circuit?

No. This is a modular disconnector / isolating switch designed for switching the circuit on and disconnecting it. For protection against short circuit or overload, a properly selected circuit breaker or other protection equipment must be used.

Where is this disconnector most commonly used?

It is most commonly used in electrical panels, automation cabinets, three-phase distribution circuits, workshops, commercial premises and industrial facilities.

Is this disconnector suitable for a three-phase electrical system?

Yes. Since the device is 3P, it is intended for three-pole circuits and can be used in three-phase electrical systems.

Can this disconnector be installed in a home electrical panel?

Yes, if the electrical panel has a three-phase circuit and the disconnector parameters correspond to the project and load. Installation should be carried out by a qualified electrician.
