OZT-*35, OZT-*45
The transformer units type OZT-*35 and OZT-*45 are manufactured in flameproof housings and equipped with the main transformer for 3.5kVA (OZT-*35) or 4.5kVA (OZT-*45) power rating. The units are equipped with two independent contactor circuits (outputs) and make it possible to supply the installations (e.g. lighting ones) with three-phase voltage of 133V or 230V or control one or two lower power motors. Voltage change of the transformer unit secondary side is performed by a user during its installation. The relays used make it possible to control the unit by connecting the standard control circuit (Roff < 600 Ω) and „low ohm" circuit (Roff < 100 Ω).

Application
Transformer units are assigned for feeding electric mining tools and lighting circuits with a decreased three-phase voltage of 133V or 230 V.
Transformers units meet to requirements of the European Directive 94/9/EC (ATEX) for equipment in group I, category M2, and can be used in methane and coal dust exsplosion hazardous areas of underground mines.

Design
The tranformers units are made in a flameproof housing. Devices are
fitted with protective devices against:
- short circuits,
- load asymmetry,
- overload,
- main channel low insulation resistance,
- short circuits, high resistance and control circuit interruptions,
- high earthing resistance
- incorrect power voltage phase sequence (optionally).
