1. Dimensions:

2. Mechanical characteristics:
The closing pressure of the steel plates is between 10/25 kg. in free contact, and consequently 12/16 kg. with the contact inserted in the dovetail or rectangular keyway. The above-mentioned dynamometer tests are ascertained at ambient temperatures between -50° and +60° with the dynamometer, having the measuring surface a circular section of approximately 646 mm2.

3 . Electrical characteristics:
The insulation resistance of the plates between themselves and towards the mass is greater than 500 Ohm in air, and after the contact has been immersed in water for 72 consecutive hours. The maximum working voltage is 24 V. at direct current. The resistance of the contact plates does not exceed 0.02 Ohm. over time and at a temperature between -50° C. and +60° C. The previously indicated checks were carried out with electronic Megger and electrical instruments.

4. Chemical composition of rubber:
Compatible with the previously mentioned characteristics, the rubber compound used is resistant to wear, abrasion, exposure to solar rays, mineral oils and sodium chloride, in particular situations present on mountain roads and in winter resorts.

5. Contact steel plates:
They are made of steel resistant to bending. The anchoring of the steel sheets to the rubber of the contacts occurs through vulcanization

6. Performance:
The contacts described above work with absolute normality in different climatic and atmospheric conditions.

7. Anti-wear protection:
A curved stainless steel plate is placed in the upper part of the contact through the vulcanization process.

8. Warranty:
1 year or 2,000,000 aces
