CG/CG2 SN Series - Two Terminal Heavy Duty Gas Plasma Arresters

Electrical Characteristics

Help	Property	Value
Minimum DC Breakover Voltage Close Info	MIN Sparkover Voltage (V)	116
Nominal DC Breakover Voltage Close Info	Nom DC Sparkover (V)	145
The maximum voltage the device can withstand without damage at rated current (I_MAX). Close Info	Max DC Spark over Voltage	174
Measured at 100V/μs. Close Info	Max Impulse Sparkover Voltage @ 100V/us (V)	500
Insulation Resistance Close Info	Insulation Resistance	1
CopF- Capacitance Close Info	Capacitance (Co) (pF)	1
Maximum pulse current which can be applied repetitively. Usually a 10x1000µs double exponential waveform, but can also be 8x20µs, if stated. Close Info	Surge Life (@ 100A 10/1000us)	20
Maximum rated peak impulse current Close Info	Impulse Discharge Current @8/20μs (kA)	10
Max AC Discharge Current Close Info	AC Discharge Current (A)	20
Once the device has switched due to a transient, it will stay in this low impedance state until the voltage across it falls below a specific value, known as the holdover voltage. When selecting one of these devices, it is important to make sure the voltage of the protected system is less than the holdover voltage value of the protector. Close Info	DC Holdover Voltage (V)	90
Refers to a device which prevents hazards due to thermal run-away. The device is a thermal sensitive switch which operates at a predetermined temperature, shorting the terminals of the protection device providing a low resistance path. Protects against the consequences of power cross conditions. Close Info	Failsafe	No
Number of Electrodes Close Info	Electrodes	2
