Catalog Description RT5/32 Surge Suppressor
Long Description
RT5/32 is a transil diode surge suppressor designed to reduce the maximum
overvoltage peak value and to limit or even completely eliminate the high pre-damping
voltage frequencies, when used or with a DC operated conventional contactor for a
rated control circuit voltage between 12 ... 32 V DC.
The operation of inductive circuits causes overvoltages, in particular on opening of the
contactor coil. The electromagnetic energy stored in the coil during contactor closing
is restored on opening in the form of surges, the slope and amplitude of which may
rise to several kilovolts. A number of drawbacks are observed ranging from
interference on the electronic devices to breakdown of insulators and even destruction
of certain sensitive components.
Advantages:
- the surge suppressor is clipped onto the top or side part in regards with the
contactor or contactor relay base design without change in device overall dimensions.
- good energy absorption - Unpolarized system - Simple, reliable system
- very fast clipping: attenuation of steep fronts and thus of high frequencies. No
operating delays.
Drawback: a certain delay on drop out which does not however reduce contactor
breaking capacity.
