How to Select the Current
Generally, it is recommended to choose about 1.5 times the rated current. For example, if the rated current is 1A, and the actual abnormal current fluctuation reaches 1.5A, 1.5A is appropriate; if the abnormal current reaches 2A, 2A is appropriate. The time of tripping (that is, disconnection) is determined by exceeding the selected A number. If the actual current exceeds the greater, the faster the trip will be. It is not immediately disconnected after exceeding the selected A number. The specific trip time is as follows:
Calibration(at25℃)
| 100%of Rated Current | Hold,No Trip |
| 150%of Rated Current | Trip Within 1Hour |
| 175%of Rated Current | 2.0-10.0 sec Trip |
| 200%of Rated Current | 1.1-5.0 sec Trip |
Approval

Mechanical/Environmental Data
Operating Ambient Temperature: -10℃ to +60℃ Mounting: Various options. See Ordering Information and drawings
Termination: 250’’(6.35mm)quick connects or solder terminals
Product Life
The number of mechanical actions is more than 3000 times, and the current impact of 6 times is more than 50 times.
Wiring Mode
Regardless of the positive and negative poles, just like a switch, the end is in and the end is out, that is, in series, the pins can be welded or 2.8MM plug springs can be used.
Typical Applications
Tarnsforms, Motors, Battery chargers, Power supplies,
appliances, extra low voltage systems, machinery.
The Difference Between Automatic Reset and Manual Reset
After the over-current protector is tripped (disconnected), manual reset (on) requires the actual current to be reset within the selected current by pressing the button. For automatic reset, the actual current will automatically reset within 60 seconds of the selected current. There is no button for automatic reset, no head, 91 series are manual reset.
