Single phase, 25 or 40 amp, din rail
contactor
|
Features
- Maximum Surge Survival™
technology -- triple layer, voltage surge protection
- Green LED for input
status
- Thermally optimized heat sink
permits edge-to-edge installations on a din rail
- Built-in snubber
circuit
- Zero crossing activation -- low
EMI, low noise to nearby electronics

inrush capability
|
- 4000 volt isolation, 1400
blocking voltage
- 1000 volt / microsecond
immunity
- Highest thermal efficiency --
less than 1.0 watt dissipated per amp switched (25 amp model) or less than 1.2
watts (40 amp model)
- CE, UL recognized, CSA
- Industry standard A1, A2, L1, T1
terminal numbers
- High density design permits more
amps per square inch
