ÜRÜNÜN TANIMI

The SN6 type transformer determined to transform high voltage, power switching, control and protection of three-phase electric devices or eventually protection of power supply mains 3/PE AC 3300V 50Hz/IT. It can work in potentially explosive atmospheres

The transformer set has the type of protection against explosion I M2(M1) Ex d [ia Ma] I Mb.The product complies with technical requirements for devices determined for use in potentially explosiveatmospheres according to Directive 2014/34EU (NV 116/2016 Sb.). The product also complies withtechnical requirements EN 60079-0, EN 60079-1 and EN 60079-11.The high voltage part of the transformer set is among others equipped with pole earthing isolator, overloadprotection and breaking contactor.

Electric circuits provide power outlet independently with:

Off-switching at short-circuit and short-circuit signalling; protection from thermal effects of overloads and signalling of overloads; off-switching in case the phase fall-out and in case the asymmetry of phases and equipment signalling; blocking the switching in case the reduction of isolation resistance of power outlet is less than 220kΩand equipment signalling; off-switching in case the reduction of isolation resistance of power outlet is less than 85kΩ andequipment signalling; blocking the switching in case the protective conductor resistance exceeds 50Ω and equipment signalling; control of the insulating state of circuit cable before on-switching using tester.
