Main characteristics

Easy to install: The device can be mounted on a panel using two retainer clips. This is a compact meter with 49 mm meter depth behind the panel that can connect up to 480 V + 10% AC L-L without voltage transformers for installation compliant with measurement category III, and double insulated.

Easy to operate: The device has intuitive navigation with self-guided menus and heartbeat LED that indicate normal functioning of your device. It also conveys the communication status when connected to an RS-485 network.

LCD display: The device has intuitive navigation with self-guided four buttons.

Standard compliance:

• Class 1.0 for active energy as per the test limits given in IEC 62053-21:2020 and IEC 61557-12 (GLDM3241 / GLEM3251 / GLEM3261 )

• Class 0.5 for active energy as per the test limits given in IEC 62053-22:2020 and IEC 61557-12 (GLEM3265 )

• Class 2.0 for reactive energy as per the test limits given in IEC 62053-23:2020 and IEC 61557-12

• Tested in accordance with IEC 62052-11 for energy test requirements

• EMI / EMC tests as per IEC 61326-1

CT nominal: 5 A or 1 A nominal current. CT reversal auto correction for energy consumption.

Password: Field configured password to secure set up information and prevent tampering of integrated values.

Cyber security: The device provides an option for disabling RS-485 port through front panel keys to prevent unauthorized access. This feature can also be used for maintenance and troubleshooting of complex communication network.

Display: The device has an auto scale and auto range display capability that provides 4 digits for Instantaneous parameters and 9+3 digits for energy parameters.

Energy counter (GLEM3251 / GLEM3261 / GLEM3265 ): Non-resettable energy counter to ensure integrity of energy readings.

Suppression current: The meter can be configured to disregard the measurement of induced / auxiliary load current in the circuit (can be set from 5 to 99 mA).

Favourite page (GLEM3251 / GLEM3261 / GLEM3265 ): The device enables user selectable parameters to be set in favourite page.

Tamper prevention: Tamper cover with sealing features for protecting against tampering with voltage and current terminals.
