Ravioli T154 / T204 DC Contactor 
​Main features of the range
All the contactors in the TECNO series are suitable for the traction and industrial material handling sectors using direct current, and are often used on lift trucks, industrial cleaning machines , duty on board ships and boats as well as road and rail transport vehicles. The TECNO 4 series of contactors described here has been designed for heavy duty and strict conditions such for example in the presence of prolonged or high rush currents.
The TECNO 4 series coils feature screw connections

Coils
The DC Coils feature terminals with 6 mm connections for the TECNO 6 series and screw connections for the TECNO 4 series.
Standard duty is : - for T 106, T 206 intermittent mode (80 %) - for T 154, T 204 intermittent mode (80 %) -
for T 106 C , T 206 C intermittent mode (50%) with maximum working time of 15 minutes ( temporary duty ).
Normalized voltage is : 12 - 24 - 36 V
Different types are available as follows : reduced consumptation coils for continuos duty - option P .

Integral protection
The cover is completely protected from oil, water and dust.

Correct use of the motor reverser
The used contactors have fast drop-out time (8 msec) and relatively long pull-in times (approx. 25 msec). In this way, safe reversals can be carried out the risk of the contacts being closed at the same time. The use of suppressor diodes, however, increases drop-out time, and therefore it is important to choose the most suitable type of suppressor (diode+resistor).

Guaranteed Quality Product
The range of TECNO series contactors is guaranteed by our EC Certificate of Conformity, available upon request, in which it is declared that such product was created by RAVIOLI in accordance to defined and recognised Safety Regulations, and in compliance with the Quality standards stated in our UNI EN ISO 9001:2000 Quality System Certificate.

Installation and cabling instructions
The TECNO contactors must be installed by a qualified staff, according to current safety law . Electrical current must be switched off before wiring.
For better loss of heat use proof cables according to the usage current. Assure that the terminal power cables are locked with nut at max clamps torque of 6 Nm.
The NC contacts are not suitable for making or breaking current. The assembling can be made by the bracket. 
Recommended working positions : either horizontal or vertical with poles set upwards. 
Operating Temperature -25°C+40°C RAVIOLI declines any responsability for damage deriving from incorrect installation or improper use of the product.
