requirement of UPS (uninterrupted power supply).
• Offers high insulation with insulation distance above 8 mm and
impulse withstand voltage of 10 kV between coil and contacts.
• Standard model conforms to VDE standards.
■Model Number Legend ■Application Examples
• Home appliances
• OA equipments
• Industrial machinery
■Ordering Information
Note. When ordering, add the rated coil voltage to the model number.
Example: G2RG-2A4 DC12
However, the notation of the coil voltage on the product case as well as
on the packing will be marked as @@ VDC.
■Ratings
●Coil
Note 1. The rated current and coil resistance are for a coil temperature of 23°C
and have a tolerance of ±10%.
Note 2. The operating characteristics given in the above table are for a coil
temperature of 23°C.
Note 3. The maximum allowable voltage is the maximum possible value of the
voltage that can be applied to the relay coil.
●Contacts
* This value was measured at a switching frequency of 120 operations/min.
●Contacts in line 2 pole
■Characteristics
Note. The above values are initial values (at an ambient temperature of 23°C.)
*1. Measurement conditions: 5 VDC, 1 A, voltage-drop method.
*2. Measurement conditions: Measured with a 500 VDC megohmmeter at the
same places as the dielectric strength.

■Engineering Data
■Dimensions (Unit: mm)
■Approved Standards
The approved rated values for international standards are different to the individually specified characteristic values. Be sure to confirm
that required standards are satisfied before actual use.
UL Recognized: (File No. E41643)
CSA Certified: (File No. LR31928)
EN/IEC Certified Model (Approval/No. 40015012)
■Precautions
●Please refer to “PCB Relays Common Precautions” for correct use.
●Differences with the G2R
The G2RG-2A4 has the same terminal arrangement as the
G2R-2A4 but the switching capacity and electrical endurance are
different. Confirm that correct operation is possible in the actual
operating conditions before using in applications.
