Power Relay
G2A-434
CSM_G2A-434_DS_E_4_1
Fully Sealed Version of G2A that Displays Its
Power in Adverse Environments
• Exhibits stable performance in an adverse atmosphere of
harmful gas, moisture, or powdery dust due to its hermetically
sealed construction.
• All the mechanical components of the Relay have been
annealed to prevent gas generation inside the Relay.
• Economical as compared with a hermetically sealed relay in a
metallic enclosure.

Note: 1.
The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%/–20% for AC rated current and
±15%
for DC coil resistance.
2.
The AC coil resistance and coil inductance values are for reference only.
3.
Performance characteristic data is measured at a coil temperature of 23°C.
4.
The maximum voltage is one that is applicable instantaneously to the Relay coil at 23°C and not continuously.
5.
For built-in operation indicator models rated at 6, 12, and 24 VDC, add an LED current of approx. 5 mA to the rated currents.

2.
The contact resistance was measured with 0.1 A at 5 VDC using the voltage drop method.
3.
The operate and release times were measured with the rated voltage imposed with any contact bounce ignored at an ambient tempera-
ture of 23°C.
4.
The insulation resistance was measured with a 500-VDC megger applied to the same places as those used for checking the dielectric
strength.
5.
This value was measured at a switching frequency of 60 operations per minute.
6.
The electrical endurance was measured at an ambient temperature of 23°C.
