Thermistor motor protection Thermistor motor protection CM-E Range Thermistor motor protection Thermistor motor protection relays Benefits and advantages Selection table Operating principle and fields of application for thermistor More 00532. The autotransformer is mechanically smaller and therefore it can be produced at lower costs. With an altitude of installation of more than m above main sea level it dinn the same as with an excessive overtemperature: Presentation of the France Transfo factories Presentation of the France Transfo factories France Transfo’s internationally recognised and highly esteemed expertise is today exported to more than 80 countries throughout the world.

Transformatoren, Drosseln und Filter engineered in Germany, made in Europe
In contrast to the complete transformer, there is only a part of the output power transferred from the input winding to the output winding with the autotransformer, by means of magnetic induction.
All power specifications refer to the collected power at the secondary side vre The transfer of the other part of the output power is effected by means of direct current conduction. General This catalogue provides a general idea of Ruhstrat s standard programme for transformers with fixed transformation ratio, constructed as toroidal core or limb core transformers.
Special transformers Railway Power transformers Special transformers Railway A leader in railway systems Our compact and low-weight transformers fully comply with the customer s specifications. Incorporated transformers Single-phase transformers up to kva Three-phase More information. The 00532 structure allows the use of transformers in dry rooms. In case of a construction with autowinding autotransformer the structural power is reduced.
Fan-coil controller for wall mounting 3 ACR2.
Safe and reliable application of overcurrent protective devices based on these sections mandate that More information. Climasys Thermal Management System. 00532 on the primary side serve for the adaptation of the transformer to different mains voltage tolerances. Depending on customer requirements and specifications the transformer windings can be produced using either copper or aluminum. Winding If not indicated otherwise, Ruhstrat Dry-Type transformers are delivered with galvanically separated windings.
There will be no special announcement of changes to information, descriptions and illustrations. Our sales team will be most pleased to consult you regarding all questions to our products. The smaller the difference between input voltage and output voltage, the larger is the structural power. For this reason, different kinds of protection are distinguished. The capital letter stands for the input winding, the small one for the output winding.
Other languages are a translation of the original instructions. Diane Malone 2 years ago Views: Bde information, descriptions and illustrations are subject to technical modification, especially with a view toward the further development of our products in accordance with the current state of the art.
LOW VOLTAGE DRY-TYPE TRANSFORMERS ACCORDING TO DIN EN (VDE /) TECHNICAL INFORMATION – PDF
The limit values for short-time operation S2 arise from fig. Further regulations, as for example certain marine classifications, can be considered upon request. Safety isolating transformers type APT Data sheet: Other international standards, including More information. To view a copy of this license, visit http: Producing our own transformers with control cabinets guarantees a high and stable quality level in all electrical components.
A high quality standard vve guaranteed by the use of high-quality materials and by the special competence of the employees.
If three-phase transformers have a neutral point star point which is lead outside, the vector group is completed by an N or n. Every product can be tailor-made according to your special application. Low Voltage Alternators – 4 pole.
The products are developed together. High-speed spiral doors for deep-freeze applications. Gde deviating kinds of load and thyristor power controller operation of the transformers must be considered when they are constructed. Insulation materials are chosen according to the required insulation coordination and the insulation class of the materials. The kinds of protection are indicated by a short sign which consists of two reference bde for the degree of protection.
The other insulations, materials are chosen according to the corresponding temperature stability class. Vertical Mounting Standard Glass Window: Possibilities of application e.

Applications deviating from the standard programme are our strong point! This insulation makes a higher protection against external mechanical influences possible as well as a long service life and high operation safety of the transformers.
