The NTE Electronics R58-3A is a thermal circuit breaker with a 3A current rating and a 250VAC/50VDC voltage rating. It is designed for panel mounting and features a pushbutton actuator for easy operation. This single-pole breaker offers a dielectric strength of 1500VAC RMS and an interrupt capacity of 2000 Amps at 50 VDC and 1000 Amps at 250 VAC.
Key electrical characteristics include continuous carrying of 100% of rating, with tripping occurring between 101% and 145% of rating at 25°C. The resettable overload capacity is ten times the rated current, and it has undergone endurance cycling of over 1000 cycles at 200% of rated load. Mechanical characteristics include resistance to 10g shock and vibration.
This circuit breaker is suitable for applications requiring reliable overcurrent protection. Its thermal tripping mechanism provides a safe and effective way to protect electrical circuits from damage due to overloads or short circuits. The quick connect terminals facilitate easy installation.
