Specifications
Maximum leakage current, each Line to Ground: |
| @ 120 VAC 60 Hz | 2 µA |
| @ 250 VAC 50 Hz | 5 µA |
| | |
Hipot rating (one minute): |
| Line to Ground | 2250 VDC |
| Line to Line | 1450 VDC |
| | |
Operating Frequency: | 50 / 60 Hz |
| | |
Rated voltage (max.): | 250 VAC |
| | |
Rated Current: | 3A |
| |
Operating Ambient Temperature Range (at rated current Ir): |
| | -10°C to +40°C |
In an ambient temperature (Ta) higher than +40°C the maximum operating current (Io) is calculated as follows: Io = Ir √(85-Ta)/45 |
