Current Ratings by Series
| Series | Current per Contact | Max Voltage | Applications |
|---|---|---|---|
| Signal | 3-5A | 50V | Data, sensors, control |
| Standard Power | 10-20A | 300V | General power |
| High Power | 30-50A | 600V | Thrusters, motors |
| Ultra High Power | 75-100A | 1000V | Custom industrial |
Factors Affecting Current Rating
- Contact size: Larger contacts = higher current
- Material: Copper alloy vs. brass
- Plating: Gold vs. silver vs. tin
- Temperature: Derating at high temperatures
- Duty cycle: Continuous vs. intermittent
Current Derating
Current ratings decrease at higher temperatures:
| Ambient Temp | Derating Factor |
|---|---|
| 25°C | 100% |
| 40°C | 90% |
| 60°C | 75% |
| 85°C | 60% |
High-Power Applications
For thruster and propulsion applications:
- ROV thrusters: 30-50A typical
- AUV propulsion: 50-75A typical
- Large systems: 100A+ (custom)
