Ordering Information
Specifications
| Maximum leakage current, each Line to Ground: |
| | @ 120 VAC 60 Hz | 0.16mA |
| | @ 250 VAC 50 Hz | 0.26mA |
| |
| 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 to 20A |
| | |
| 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
