Pacemaker switch type WROT 2x1400.4A is made in flameproof enclosure type ZAP-BLA1 and it is used for soft start power supply and protection of 4 driving motors of belt tensioning or scrapers with voltage 3x1000VAC or 3x500VAC. Additionally it can supply 2 belts tensioning engines (reversal work) it has supportive transformer to power supply 4 clearances with voltage 3x230VAC or 3x500VAC with possibility of supporting the armature voltage of 42VAC.

*We reserve the right to change parameters
- 2 power tracks
- 4 drains for the conveyor (2 on each track)
- 2 outflows for a tension station (reverse operations)
- 4 outflows for releasers 3x230VAC and 42VAC
- 2 drains voltage auxiliary 42VAC
- 2 thyristor modules for soft start
- 2 systems for a thyristor module control
- reverse switch for each track
- protection from: overload, short circuit, asymmetry, discontinuities ground wire, decrease the insulation resistance on the drains, engine temperatures, the temperature of thyristors
- intrinsically safe control circuits
- control of four clearancesi
- tensioning control station
- lock the door opening from the main chamber
- ability to work on stiff
- digital ammeters
- voltmeters inlet
- signaled control work
- visualization (on request)
- cooperation with well-known automation systems
