SWITCHES WITHOUT COMPROMISES. Katko is a Finnish family business specialising in safety switches, load break switches and fused switches with more than 70 years of experience. Not all safety and load break switches on the market come from specialised manufacturers by any means, and that is precisely why we are so proud of ours. We design and manufacture every product ourselves in our own factories. The challenging Finnish climate creates a basis for developing switches that work in all conditions across the globe. Switches without compromises. This is what we at Katko think, as did the...

Data subject to change without notice © Load Safe SWITCHES ACCORDING TO IEC 60 947-3 SWITCH PROTECTION AGAINST OVERVOLTAGE A mechanical switching device capable of making, carrying and breaking currents under normal circuit conditions which may include specified operating overload conditions and also carrying for a specified time currents under specified abnormal circuit conditions such as those of short circuit. Note: A switch may be capable of making, but not breaking, short-circuit currents. Uimp (Impulse withstand voltage) defines the device’s use in abnormal network conditions with...
