Marechal EVO The First Separable, Switch-Disconnector

MARECHAL EVO

A Separable Switch & Disconnector

Marechal Electric is at the heart of innovation with the invention of the first switch disconnector up to 40A and first separable switch disconnector. The uniquely and ergonomically designed Marechal EVO combines three products in one – switch, disconnector and plug offering greater safety, easier use and less space for installation.

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.

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.

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.

Below describes the features and benefits of Marechal’s new twist and switch technology.

Marechal EVO | The First Separable Switch-Disconnector

DISCONNECTOR, SWITCH, PLUG

Marechal EVO is created mainly to enhance the safety for user and installations. Its flawless design enables the opening and separation, even if there is an overintensity or overvoltage default. Nowdays, with a typical switch-disconnector, in case of overintensity, you can’t be guaranteed of the disconnection if the contacts melt. With EVO, the division is apparent as the product is split into in two parts.

TWIST AND SWITCH, SEPARATE

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.

Marechal EVO – First Detachable Switch-Disconnector

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.

EVO40 SEPARABLE SWITCH DISCONNECTOR

The unique technology incorporates functionalities of a 40A switch, a disconnector and an industrial connector available with self-cleaning silver contacts with silver tips and bespoke “twist” mechanism.

Merging three products into one streamlines your electrical installation and the ergonomic design makes managing and cleaning simpler. The product is watertight (IP66 / IP67), in the ON and OFF positions.

Safety is Marechal’s main priority when it comes to the EVO40. A visible and detachable break ensures the safe isolation of any low electrical circuit (AC-23 18.5 kW, AC-3 11 kW).

EVO40 complies with the IEC 60204-1 standard for machine safety and the switch disconnector is adapted for all motor plugging configuration up to 6 poles + earth.

A strong and durable switch that can be installed on a wall or in-line for mobile installations and can be lockable and padlockable in ON and OFF positions.
