Temperature Range
Environmental Information marked with “Snowflake” approval for -25°C to 40°C (-13°F to 104°F) ambient
temperature. (Temperature effect on RC: for every 10°C temperature rise above 40°C decrease RC by 7%.)
Fluctuating Climate Conditions
Electrical Shock Protection
To maximum 45°C, 95% relative humidity.
Uninsulated electrically live parts within 30mm of the operating handle are “finger safe” (terminal screw
heads) and uninsulated live parts within 100mm of the operating handle are “back-of-hand safe” (terminals).
15g with impact force half-cycle sinusoidal and 11ms duration, 18 impacts total with 6 on each principal axis
(3 impacts each face). FI is DIN Rail mounted during the test, and electrically loaded with 25% of Fault RC.
Successful testing required no trip during the test, no damage and no loosened parts.
Impact/Shock Protection
5g, at frequency of 55Hz to 2,000Hz, applied for 35 ± 5 minutes along each of the three principal axes, plus
5 minutes of application at every established critical resonant frequency. FI is DIN Rail mounted during the
test, and loaded with 25% Fault RC. To pass, the FI did not trip at 25% Fault RC, but did trip between each
of the principal axis tests when the fault current was raised to 125% Fault RC, and there was no damage
and no loosened parts. Suitable for machinery and mobile vehicle applications.
Vibration/Seismic Resistance
Ingress Protection (IP) Class 40; internal working components and live parts (excluding terminals) are
protected against ingress of solid objects greater than 1mm diameter (class 4-), but have no protection from
ingress of water (class-0).
Housing Class
The FI is tested and approval stamped for tripping sensitivity to non-sinusoidal fault currents, which become
zero or almost zero within one cycle of the line frequency. Waveforms and allowed trip-current ranges are as
follows:
Non-Sinusoidal Fault
1.
AC Sinusoidal Fault - 0.5-1.0 times Fault RC
2a.
2b.
Pulsating DC Fault;
Positive and Negative Half-Waves - 0.35-1.4 times Fault RC
Phased Half-Wave, 90° - 0.25-1.4 times Fault RC
Phased Half-Wave, 135° - 0.11-1.4 times Fault RC
3.
Pulsating DC on 6mA
DC (continuous) Base - Max. 1.4 times Fault RC + 6mA
At VDE rated voltage, suitable for Class C environments with relatively high dust and moisture levels and
little HVAC control, e.g., industrial, commercial, agricultural; on machine tools, hoists, warehouse equipment,
etc.; in boiler rooms, unheated storage, covered shipping/receiving, open workshops, etc.
