Superimmunized differential switch 4P 40A 30mA TERTIARY Schneider A9R61440

Switch differential superinmunizado 4P 40A 30mA TERTIARY Schneider A9R61440

• immunity against false alarms.: 3kA crest for the instant and 5kA crest for the selective according to wave 8/20
• Class "yes" superinmunizados
• Timing: instant

Differential switch suitable for electrical installations with:

• Risk of false alarms. caused by lightning, fluorescent lighting, maneuvers, sudden stops in the network, transients... etc
• Risk of no tripping of the differential by blinded due to:
  • Presence of components continuous.
  • The range of “if” also avoids the risk of no tripping of the differential due to internal corrosion in certain applications exposed to corrosive atmospheres such as:
    • Compounds of chlorine.
    • Ozone.
    • Sulphur.
    • Oxides of nitrogen.
    • Sea salt.
    • Moisture.
