Panel (Flush) Mount enclosure
Adjustable side clips provide quick method of mounting (no fixing screws required)
6 models available (3A, 10A or 30A with either SPDT or 2 x N.O. relay outputs)
Designed to monitor and detect true RMS leakage current in conjunction with separate toroid
Adjustable Trip level (I∆ ∆ ∆ ∆ n) and Time delay (∆ ∆ ∆ ∆ t) settings
Separate "Test" and "Reset" push buttons
Toroid open and short-circuit detection forces unit to trip (Red LED flashes during this
condition)
Relay energises when fault current exceeds set Trip level
LED indication for Power Supply, Leakage Current and Trip status
SPDT relay output - 8A
2 x N.O. relay outputs - 3A
Single supply voltage option – 115V or 230V AC
Compliant with IEC 60755
5. Green "Leakage Current" LED indication
6. Red "Tripped" (Fault) LED indication
7. "RESET" button

Type: P50ELR* & P50ELR*/2
(Part No. P50ELR-3, P50ELR-10 and P50ELR-30)
(Part No. P50ELR-3/2, P50ELR-10/2 and P50ELR-30/2)
• INSTALLATION AND SETTING
• BEFORE INSTALLATION, ISOLATE THE SUPPLY.
• Remove the P50ELR from the packaging.
• Lift the raised part of the side clip and slide towards the rear of the
housing to remove. Carry this out on both sides.
• Insert the P50ELR in to the panel cut-out and fit the side clips back
on to the housing.
• Slide the clips towards the front of the unit until they come in to
contact with the reverse side of the panel. The unit is now secured
in place.
• Connect the wires to the rear terminals as required following the
diagram shown on the next page and for the relevant model shown.
• Ensure the Auxiliary supply voltage to be connected to terminals 1
and 8 matches the rating of the product.
Setting up
• The unit should be set according to the requirements of the
application.
Applying power
• Apply power and the green "Power on"
• Assuming no fault present, the output relay(s) will remain in the de-
energised state.
• Prior to a fault occurring, the LED bargraph
I∆n being detected (the display is scaled between 25, 50, and 75%
of the actual trip level). After all 3 LED's have illuminated and the
unit trips due to an excessive fault current, the red "tripped"
will illuminate.
Fault simulation (Test mode)
The unit can be placed into a fault condition by pressing the "Test"
•

button on the front of the unit. The output relay(s) will energise.
Press the "Reset" button
•
output relay(s) revert back to the de-energised state.
The unit can also be reset by interrupting the power supply.
•
To satisfy regulations, it is recommended that the device be tested
•
periodically to ensure correct operation.
Troubleshooting
If the unit fails to operate correctly check that all wiring and
•
connections are good.
Note:
The operating function of this unit is classed as a Type A
tripping is ensured for residual sinusoidal alternating currents and
residual pulsating direct currents, whether applied suddenly or slowly
rising. Additionally, this unit is protected against nuisance tripping.
This unit will also satisfy the requirements for Type AC devices which
only need to detect residual alternating currents.
