| Protection Techniques and Common Failure Modes | |||||
|---|---|---|---|---|---|
| Load | Load Example | Protection | Diagram | Common Failure Modes | Failure Mode Description |
| Resistive (DC) | Indicator Lamp, Heaters | Current Limiting Resistor | In-rush Current (Switching) | In-rush current exceeds rating and welds switch closed | |
| Over-Current (Carry) | Carry-current exceeds rating and switch welds or burns open like a fuse | ||||
| Inductive & Capacitative (DC) | Relay Coil, Solenoids, Motor | Reversing Diode | Over-Voltage (Arcing) | Voltage arcing during switching weldscontacts closed | |
