Type Tests
Electrostatic Discharge (ESD)
8 kV contact discharges and 15 kV air discharges applied in accordance with IEC 801-2 ESD.
Dielectric Strength
1500 Vac at 50/60 Hz in accordance with IEEE C37.90
The RS-232 serial communication port is intended only for periodic use and is not subject to the
requirements of IEEE C37.90.
Surge Withstand Capability—Oscillatory and Fast Transient
Qualified to IEEE C37.90.1-1989
Standard Surge Withstand Capability (SWC) Tests for Protective Relays
and Relay Systems.
The RS-232 Serial Communication Port is intended only for periodic use and is not
subject to the requirements of IEEE C37.90.1.
Radio Frequency Interference (RFI)
Type tested using a 5 W, hand-held transceiver in the ranges of 144 and 440 MHz with the antenna
placed within 6 inches (152 millimeters) of the relay.
Shock
In standard tests, the relay has withstood 15 G in each of three mutually perpendicular planes without
structural damage or degradation of performance.
Vibration
In standard tests, the relay has withstood 2 G in each of three mutually perpendicular planes, swept over
the range of 10 to 500 Hz for six sweeps, 15 minutes each sweep, without structural damage or
degradation of performance.
