RESYS P40

Type A earth leakage relays

for motor load break

RESYS P40
RESYS P40
Function
  • RESYS P40 earth leakage relays associated with a remote trip breaking device (automatic power breaking), provide the following functions:
    – protection against indirect contact,
    – limitation of leakage currents.
  • They also preventively monitor electrical installations via their (configurable) pre-alarm function or when used as signalling relays.
Advantages
Fully configurable
  • 2 relays with configurable function (alarm or pre-alarm at 50% IΔn).
  • Adjustment of IΔn from 0.03 to 30 A.
  • Time delay 0 to 10 s.
  • Positive or negative security configurable by the user.
  • Selection of toroid ratio.
Tripping accuracy by TRMS measurement
  • Improves immunity to nuisance tripping.
Instantaneous display of permanent leakage currents
  • The LED bargraph provides a real-time display of fluctuations in leakage currents.
Compact 48x48mm panel-mounted unit
  • The adjustment buttons are protected by a sealable cover, while the display of available alarms is displayed directly on the front face of the device.
Improved immunity to EMC interferences
  • The device has new electronics which improve electromagnetic compatibility.
Applications
application RESYS P40
Rapid recognition of an insulation fault increases the availability of the distribution network by preventing accidental power cuts and the resulting loss of production. RESYS P40 are particularly suitable for insertion in electricity control panels with withdrawable compartments.
Protection against fire or explosion risks
  • The use of Residual Differential Devices (with adjustment IΔn ≤ 300 mA) provides protection against the risk of fire or explosion generated by tracking currents to earth, in areas classed as BE2 or BE3 respectively. This protection is mandatory in TT, TN and IT neutral systems.
