25A Thermal Circuit Breaker
25A Thermal Circuit Breaker – Easy, Reliable, and Safe ProtectionProtect Your Circuits with a 25 Amp Thermal Circuit Breaker
Keep your appliances and DIY projects safe with this 25A thermal circuit breaker. Designed for daily use, it offers simple reset functionality and prevents overcurrent damage in your home or workshop electrical circuits.
Easy Installation and Operation
The NTE R58-25A thermal circuit breaker uses standard .250" (6.35mm) quick connect terminals for hassle-free panel mounting and wiring—no special tools required. The push-button reset lets you quickly restore power once the issue is fixed, and a visual trip indicator makes troubleshooting fast and easy.
Reliable, Resettable Overload Protection
- Current Rating: 25 Amps (25000mA)
- Maximum Voltage: 50 VDC or 250 VAC (50/60Hz)
- Typical Resistance: 0.005 Ohms
- Interrupt Capacity: 2000A @ 50VDC, 1000A @ 250VAC
- Resettable: Push-button for simple manual reset after trip
- Trip Indicator: Visual indicator for quick identification of tripped status
- Cannot be manually tripped
Performance You Can Trust
This 25 amp thermal breaker is tested for over 1,000 cycles at 200% rated load and can withstand up to 10g shock and vibration. It will continuously carry 100% of its rated current and is calibrated to trip between 101–144% of the rating (must trip at 145% at +25°C).
