A Special Report for Control Engineers

• Sensor and valve cables get very hot, melt or catch fire without the breaker reacting
• We have to shut down the machine to reset a breaker, repair sensor cables or replace a fuse
• We have to open the control cabinet to see which breaker or fuse failed, and keep the cabinet
open to troubleshoot a circuit
• The power supply shuts down during a short circuit or overload
• We oversize our power supply to prevent it drawing down before our breakers trip
• We oversize our breaker or fuse to avoid them blowing during machine start-up
• We have to keep many different breakers and fuses in stock
