Tesla D1308 | Thermal Overload 2.5-4Amp
The Tesla D1308 is a thermal overload relay with an adjustable range of 2.5-4A, designed for reliable motor protection in coordination with D09–D32 contactors. It safeguards motors by tripping during prolonged overcurrent, helping prevent overheating and mechanical failure. Ideal for use in pumps, fans, conveyors, compressors, and HVAC systems, it supports extended motor life and system safety.
Thermal overload relays provide time-delayed protection, simulating how a motor heats under load. Unlike circuit breakers, which respond instantly to short circuits, the D1308 is built to detect sustained overloads, making it essential for motor control circuits.
Tesla D1308 Features
- Adjustable 2.5-4A setting: Tailored overload protection for small motors
- Suits D09–D32 contactors: Seamless integration with standard control gear
- Trip reset options: Manual or automatic reset depending on application
- Accurate overload detection: Tracks thermal buildup to prevent damage
- Standardised mounting: Designed for easy fitment to Tesla motor starters
Where to Use the Tesla D1308
- Pumps and compressors: Prevents damage during continuous heavy loads
- Fans and blowers: Reliable protection in extended-run applications
- Conveyors and machinery: Helps avoid costly motor failure
- HVAC systems: Provides overload safety for smaller motor-driven equipment
