| Parameter | Specification |
|---|---|
| Heat-output condition | ±20%; ambient +25 °C, vertical installation, indoor conditions with good natural convection |
| Rated supply | 220–240 VAC, 50/60 Hz |
| Fan | 80 mm square × 38 mm; axial ball-bearing; source states 5000-hour life without test conditions |
| Heater / heat-transfer body | Ceramic PTC / aluminum alloy |
| Terminal | 925-3, three-position push-operated spring; component rating 16 A |
| Wire / strip length | Source lists 18–12 AWG and 0.5–2.5 mm²; confirm exact approved range; strip 8–9 mm |
| Dielectric withstand | 1500 VAC, 50/60 Hz, 1 minute |
| Insulation resistance | 100 MΩ at 500 VDC |
| Humidity | ≤90% RH |
| Operation / storage | Main chart: −40 to +70 °C / −40 to +120 °C; no condensation or icing |
| Protection / safety class | IP20 / Class I |
| Illustrated outline, H × W × D | 140 × 80 × 80 mm |
| Terminal markings shown | L (1), N (2), PE (3) |
| Item | Published difference |
|---|---|
| Supply / airflow | Gallery says 220 V and 40 m³/h (24 CFM) without the 600 W distinction |
| Mass | Gallery lists 780 / 790 / 800 g across models; conflicts with main chart |
| Storage | Gallery says −40 to +70 °C; main chart says +120 °C maximum |
| Surface temperature | Approximately 74 °C at ambient 25 °C in gallery; not a guaranteed safe-touch limit |
| Fuse type | Gallery recommends time-delay fuses of 4 / 6 / 8 / 12 A |
| Peak-current notation | Gallery lists 4/2, 6/4, 8/6, 12/10 without defining paired values |
Selection & installation notes
- Confirm the exact revision for mass, airflow, storage limits and paired current notation. Do not interpret the undefined pairs as steady-state operating current.
- Install vertically with unobstructed airflow and verify the required clearances and thermostat arrangement.
- Class I construction requires protective-earth connection. Follow L/N/PE markings and the approved wiring diagram.
- PTC self-regulation is not a substitute for cabinet temperature control. Select supply protection for starting current and installation conditions.
- Disconnect power and allow hot surfaces to cool before service. The source does not provide fan-life test conditions or model-specific clearances.
