Switch, isolator, connector: Marechal Electric explains the benefits of its new separable switch disconnector.
In April 2019, Marechal Electric launched its first switch disconnector 40A and the first separable switch disconnector – EVO – allowing users to connect and disconnect safely.
Switch, disconnector and connector – it merges three products in one, for easier use and less volume.
EVO’s creation is in-line with Marechal Electric’s aim to increase safety for users and installations. Its infallible mechanism allows for opening and separation, even if there is an overintensity or overvoltage default.
Today, with a classic switch disconnector – in case of overintensity – you can’t be assured of the disconnection if the contacts melt and merge. With EVO, the sectioning is visible: the products is separated in two parts.
Furthermore, its rotary switching introduces a new safety feature to the industry. By aligning both ‘Os’ indicated on the product, the two parts of the switch disconnector are brought together without any power; it is ‘out’.
With a twist movement, the product is moved into the ‘off’ position; it is ready to be connected, but there is no power going through. In this position, it is a watertight, disconnected product. Finally, a last twist movement puts the product in the ‘on’ position; it is powered but still watertight.
The Marechal Electric switch disconnector 40A adapts to harsh environments: -25°C to +60°C. With EVO, the separation shows the exact position of the contacts and ensures 100% safety during any maintenance operation. It is made of quality materials and offers great flexibility in the most demanding applications in terms of hygiene, robustness and reliability.
It can be used in all industries and is particularly easy to install: only one tool is needed. With a screwdriver, the installer can easily install the switch isolator.
EVO40: technical features
Equipped with self-cleaning silver contacts with silver tips and a patented, unique ‘twist’ mechanism, this new technological concept combines the functionalities of a switch, a disconnector and an industrial connector.
The combination of three products in one simplifies installation and reduces the time it takes. Furthermore, its ergonomic design was designed to make the handling and cleaning easier: the product is watertight (IP66/67) in the ‘on’ and ‘off’ positions.
Safety is the company’s watchword, therefore access to the active parts of the product is made impossible, ensuring that it can be used safely. Its visible and separable break guarantees the safe isolation of any low electrical circuit (AC-23 18.5 Kw, AC-3 11 kW). Through its certifications, EVO40 complies with the IEC 60204-1 standard for machine safety. Finally, this new switch disconnector is adapted for all motor plugging configuration up to six poles and earth.
