Perfectly combines the benefits of a socket with the power of a switch
Connect and disconnect your appliances in complete safety
Backed by 70 years of research and innovation, the DECONTACTOR™ offers a level of reliability and safety unrivalled anywhere in the world. It allows appliances to be connected and disconnected thousands of times in the most demanding of environments, while eliminating any risk of an accident.
An unrivalled level of safety
Based on MARECHAL® technology, the DECONTACTOR™ plug socket-outlet enables you to connect and disconnect loads of up to 250 A/110 kW, without the addition of a pilot wire or associated switch, quickly and safely. So there’s no need for qualified personnel.
You can connect and disconnect your machines in a matter of seconds:
Guaranteed compliance of your electrical installations
DECONTACTOR™ meets all your operating constraints and complies with standards and regulations. Installed close to a motor or machine, it ensures the safety of operators against accidental start-up of electrical machines by performing the following functions:
No arcing
No access to live parts
Load breaking capacity up to 250 A
Lockout capability of the installation
Ease and cost-effectiveness of installation
Very compact
DECONTACTOR™ PLUG SOCKET-OUTLET WITH INTEGRATED SWITCH
CLASSIC PLUG SOCKET-OUTLET – IEC/ EN 60 309 – 2 industrial socket with switch
63 A product (same scale)
A simple push of the button cuts the current and prevents any risk of electric shock. The plug is then de-energised. The DECONTACTOR™ allows you to comply with installation regulations without adding a control circuit or switch upstream.
BREAKING POWER
MARECHAL® DECONTACTOR™‘s are all fitted with end contacts with silver-nickel caps. They ensure exceptional connection and disconnection quality under load.
Silver, even oxidised, is an excellent electrical conductor. Conductivity is optimal even in the presence of vibrations and temperature variations, thanks to the pressure exerted by the springs on the caps. MARECHAL® contact uses a crimped braid with a spring to ensure superior performance and tolerances to pin and socket contacts. The flexibility of the braid ensures that the base contact cap is always perfectly aligned with the plug contact cap. MARECHAL® contacts all feature a surface treatment offering better corrosion resistance than copper or brass.
Loose terminals (and the resulting overheating) are one of the main causes of failure in electrical installations. It is caused by various factors:
MARECHAL® contacts are fitted with “spring loaded” terminals. The wire clamp is split and circled by an elastic ring. This means that a constant clamping force can be maintained even in the presence of the risk factors listed above. The conductor is permanently and perfectly connected to the contact terminal, which avoids tightening operations.
Decrease in production downtime.
Fewer and simpler maintenance operations.
Discover how the DECONTACTOR™ minimises overheating and optimises the energy efficiency of an installation, resulting in lower power consumption.
OVERHEATING
COMPARATIVE OVERHEATING CURVE
The sockets are fitted with a locked safety disc which prevents access to live contacts with a finger (IP2X/IPXXB) or with a tool ≥ 1 mm in diameter (IP4X/IPXXD). This disc can only be unlocked using a compatible plug, preventing any risk of electric shock.
MARECHAL® equipment uses glass-fibre reinforced polymer (GRP) or metal casings, depending on the model. This choice of material gives the socket-outlet excellent mechanical performance and contributes to its longer lifespan.
ROBUSTNESS
The Protection Index (IP) assesses a product’s resistance to the intrusion of solid and liquid matter.
Sealed to IP66/IP67/IP69 standards, MARECHAL® equipment can be used in the most demanding environments and withstands frequent washing in production areas, such as high-pressure and high-temperature cleaning.
SEALING
The DECONTACTOR™ can be fitted with auxiliary contacts for transmission of low currents
AUXILIARY AND PILOT CONTACTS
Lockout prevents unintentional power supply or use of equipment during maintenance. The DECONTACTOR™ can be used as part of Lockout Tagout procedures (LOTO). Close to your machines or electric motors, lockout ensures the protection of your employees, without the intervention of a qualified electrician. MARECHAL ELECTRIC offers you a simple and quick locking system, which can be used on connected or disconnected plug socket-outlets.
Lockout
There are 17 different voltages in the low-voltage field, and several of them can coexist on the same industrial site. To these must be added different frequencies or the increasingly frequent need for direct current (production or storage of alternative energy, solar panels, wind turbines, etc.).
Our 24 fool-proofing positions allow you to create unique combinations of polarities, voltages and frequencies. As a result, only sockets and connectors designed with the same coding can be connected together.
Example of coding
MARECHAL®‘s unique fool-proofing system also enables plug socket-outlets to offer a “dual voltage” system. In fact, a single plug socket-outlet, for example 3P+N+E, offering 220/250 V AC and 380/440 V A at 50 Hz, can safely supply 4 plugs with the same coding, but different polarities and/or voltages:
Having two voltages delivered by the same socket significantly reduces the number of sockets installed and saves money.
