Marechal EVO

First Separable Switch-Disconnector

MARECHAL ELECTRIC is at the heart of innovation with the invention of the first separable switch-disconnector. The unique technology of the EVO incorporates functionalities of a 40A switch, a disconnector and an industrial connector. The Marechal EVO was created to provide enhanced safety for users and installers.

➡ Thorne & Derrick are official distributors and stockists of Marechal plugs and sockets in the UK.

Thanks to the innovative « Twist & Switch » design, EVO offers a positive break indication that reflects the exact position of the contacts. Also referred to EVO40 (40A) is a detachable switch disconnector with rotary manual control from 2 to 6 poles.

The First Separable Switch-Disconnector

EVO40 is a manually operated separable switch-disconnector, with configurations from 2 to 6 poles + Earth. Compliant with IEC/EN 60947-1 and 60947-3 standards, EVO40 allows for frequent making and breaking on load, while ensuring safe isolation of any low voltage electrical circuit: resistive (AC-21A), mixed resistive/inductive (AC-22A) or inductive (AC-23A).

EVO40 also allows for on load making & breaking of all electric motors (AC-3), as per IEC/EN 60943-3 standard requirements. Equipped with self-cleaning silver alloy contact tips and a unique and patented mechanism, our new technological concept combines the functionalities of a switch and an isolator. The design facilitates successive double breaking pole by pole, which ensures optimal safety during any maintenance operation.

Separable Switch-Disconnector


Once the supply and load parts have been separated, a safety shutter prevents any risk of electric shock (IP4X/IPXXD). The robust mechanism allows distinctly and visibly separated disconnection and separation even in the event of overload currents.

Thanks to the compact design, EVO40 can be configured to be panel-mounted or flush-mounted on a wall box with varying angles. Other standard features include: padlockable accessory, hidden screws, and a smooth, crevice-free design.

The quality of EVO40 materials offers flexibility in the most demanding of applications in terms of hygiene, robustness and reliability (IP66/IP67/IP69 and IK09): Halogen-free; UL94-Standard compliant self-extinguishing materials; resistant to hot vapours (tropicalisation as per IEC 60068-2) as well as UVs (class f1), corrosion and chemical agents.

Conventional Solution Compared To EVO Solution


  • Electrical machinery to the “Machinery” European Directive on isolating device, and to standards EN 12100 and EN 60204-1,
  • Electrical installations to installation standards: IEC/HD 60364 and NF C 15-100 (French) or other national transposition

EVO complies with the following standards:

  • EC/EN 60947-1/-3/-4/-5 : Low-voltage switchgear and controlgear – Part 3: Switches, disconnectors, switch-disconnectors and fuse-combination units



The industry has a new safety reflex thanks to its rotary twist: lining up both “O” and placing simultaneously the two parts of the switch disconnector without any powering. Twisting the EVO into the “OFF” position means it is prepared for connection without any power running through it.

The main benefit of the EVO in this position is to have a waterproof product without power.

Twist once more to place the product into the “ON” position meaning the EVO is powered but still watertight.

​EVO offers a positive break indication that reflects the exact position of the contacts.

EVO is a switch-disconnector with visible and fully apparent breaking. As such, it is not subject to the obligation of a 30 mA residual current device (RCD).

EVO allows:

  • continuity of service: no unwanted tripping, no production loss;
  • space saving and cost reduction;
  • securing and simplifying interventions: for maintenance or replacement of an equipment, EVO can be separated in two parts, by means of a tool, and padlocked. When separated,
    EVO has an IP4X/IPXXD rating. It is therefore not necessary to use authorized personnel or protection procedures

Suitable for arduous environments with an operating temperature of between -25°C to +60°C as the separation shows the exact position of the contacts and promises 100% safety during any maintenance operation.

The design of the EVO provides greater flexibility and suitability in the most challenging applications in terms of hygiene, robustness and reliability.

The switch disconnector manufactured by Marechal can be used in all industries as it is very easy to install: only one tool is needed!  Using a screwdriver the installer can easily put the switch isolator in the correct place.
