PACEMAKER FLAMEPROOF THYRISTOR SWITCH TYPE WROT 1400.2A
Pacemaker switch type WROT-1400.2 is made in flameproof enclosure type ZAP-BLA1 and it is used for soft start power supply and protection of two driving motors of belt tensioning or scrapers with voltage 3x1000VAC or 3x500VAC. Additionally it can supply 2 belt tensioning engines (reversal work) it has supportive transformer to power supply 2 clearances with voltage 3x230VAC or 3x500VAC with possibility of supporting cramps with voltage 42VAC and tapping with voltage 3x127VAC or 3x230VAC.
