Happy birthday 3120! 🎉 Our circuit breaker / switch combination 3120 is celebrating its 40th birthday this year. To reduce the number of components, we integrated the overcurrent protection into the mains switch. Due to its high reliability and cost-saving dual function, the circuit breaker has become indispensable for many manufacturers of devices and machines, for example in heart-lung-machines or dialysis-machines. Erich Rotter was part of the development team at the time and still works at E-T-A today - as the product specialist responsible for the 3120. Over the years, we have continued to develop the circuit breaker. 👉 Fun fact: If we lined up all the 3120s ever produced, the line would be around 1,500 kilometres long - that's the distance from Altdorf to Barcelona!
