Question & Answers

The standard DIN EN/IEC 61439 replaced the standard 60439 at the end of 2014. The standard describes the design and test specifications for low-voltage switchgear and control gear assemblies. The standard defines the safety requirements for devices that are used to distribute electrical energy in industry, in private households and on construction sites. The standard guarantees a higher safety standard and is used, for example, for energy distributors, switchgear and distribution cabinets. More information can be found here

Rising temperatures can result in the formation of condensation in receptacle combinations. Special membrane screw connections for protection type IP67 enclosures ensure an exchange of air and prevent evaporation. In practical application, feeding from below has proven to be effective.

7-pin plugs and sockets can be used, for example, to regulate, control and monitor devices in industry, agriculture and the trade. To this end, see also page 76-78 of our Industrial plugs and sockets catalog. Our 7-pin plugs and sockets can be found here.

Our EverGUM® combination units are suitable for free-standing floor applications. A stand is therefore not required. 

Yes - a current table with the IP protection types can be found here and in our Industrial plugs and sockets catalog on page 104.

Yes, MENNEKES has several solutions available:

• Our stainless steel receptacle combinations, CombiTOWER, energy bollards and Cepex receptacles are equipped with a lock cylinder and can therefore be locked – perfect protection against unauthorized access.
• We would also be happy to equip our DUO interlocked receptacles and the windows of our receptacle combination enclosures with a padlock on request.

A single feeder is used with these receptacle combinations as standard, for example, to a residual current circuit breaker. We would be happy to install a terminal block for larger supply lines or a conductor line on request and as specified by you, for example, with the dimensions: 2 x 5 x 25 square mm.

Three-phase sockets must be connected in such a way that there is a clockwise rotating field. The rotating field control test plug differs from normal plugs due to its transparent enclosure. By means of two control lamps inside the transparent enclosure, this plug indicates whether the field is rotating in a clockwise or anticlockwise direction, or if a phase is missing. In this way, the direction of the rotating field can be checked safely. If the rotating field is correct, the green lamp lights up; if the rotating field is incorrect, the red lamp lights up and if a phase is missing, both lamps light up. You can find our test plug here. More information can be found on page 34 of our Industrial plugs and sockets catalog.

This is theoretically possible up to 32 amperes - but a plug should never be pulled out under voltage!

The maximum cross-section of a pilot pin is 4mm².
