Are you working with currents between 20 and 40 A at an operational voltage of up to 1000 V? The COMBICON plug-in terminal blocks of the PC4, PC5, and PC6 series from Phoenix Contact are ideal for reliably and safely transferring higher currents.
Only a 15mm automotive relay FBR51ND12-WI switches up to 35A. The Japanese have pressed many years of experiences and precision into a small relay. However, reliable and also by us proved relay will find a wide range of applications outside the car.
