Movable switches for Chorine cells generate a short circuit and a bypassing of the current for in-line cells. The operating current will be up to 200 kA. The connecting surface "switch to cell" is from the dimension like a sheet of paper DIN-A 4. Current density, uniformly distribution of the current and the switching under load is an outstanding challenge.
Chlorine switches with a shaft length up to 12 meter
Fixed installed short circuit switches for Chlorine cells in-line needs shaft length up to 12 meter. The operating current and switching capacity will be up to 180 kA. Ritter delivered to many customers switches with synchronised operation and a perfect uniformly current distribution for the whole lifetime.
Movable switches for the Graphite industry
A special challenge is the dust and dirt in a Graphite plant. The switches will be moved from one graphite stove to another graphite stove and arrange the power supply by contacting a busbar at the ceiling. Ritter switches enables the contact to 240 kA rated current under dust and heat.
World biggest DC Breaker
Switching capacity with rated current 72 kA under 12 kV DC power supply, no problem for the Ritter DC-Breaker; and the insulating distance enables a safe personal safety. World record.

Safe and visible isolating distance
Small space requirements
Small maintenance efforts because of simple and ruggedized construction
Long lifetime
Comprehensive optional supplementary equipment
Area of application
The new Disconnector type RIT is a further development from the existing type RGT and RNT. The indoor- Disconnector is type tested according to IEC/EN 60694 and IEC/EN 62271-102. The Disconnector is suitable to open and close electric circuits, if there are negligible low currents to be disconnected or if there is no significant difference in the voltage between the electric circuits which shall be separated or the electric circuit which shall be connected. In the open position a clear visible isolating gap will be formed between all the poles of the Disconnector. The insulation level refers to normal air conditions at sea level. For installation altitude above 1000 m consider reduction of insulation level.

High-current disconnect switch - 27 - 150 kV, 400 - 2 000 A | GB series
Heavier-duty, high power GB series is designed with sliding multiple finger contacts. These contacts minimize power loss due to environmental contamination because of the cleaning action of the wiping contact fingers. Standard units are for low current make or break. Arcing contacts can be added for higher current make only. They do not have an interrupting rating. Available in single pole, single throw, single or multi-pole, and double throw types, these switches are rated at 27 to 150kV PK test and 400 to 2000 amps RMS continuous; to 60,000 amps momentary, 10 cycle, and to 400,000 amps capacitor discharge, 20uSEC RC. Also available with 2 or more SPDT electrical auxiliary contacts or air valve type position indicators as optional accessories.

High-current disconnect switch - 24 - 750 kV, 400 - 8 000 A | GD series
The GD series, 80-120PSI air actuated, single pole/single or double throw switches can be water or oil cooled in some models. Available are maximum continuous ratings of up to 8000 amps continuous in air, higher with cooling or parallelling. Contact ratings reduced to 70% when parallelled. Extremely compact for their rating, this series is available in modular block form and can be stacked in parallel for increasing current handling capabilities. Many other models are available.
