TOMZN TZG40-PV 2 Pole DC SPD 600V DC Surge Protective Device 20kA–40kA for Solar Systems

TOMZN TZG40-PV 2 Pole DC SPD – 600V DC, 20kA–40kA Surge Protection

Protect compatible DC electrical installations against transient voltage surges with the TOMZN TZG40-PV 2 Pole DC Surge Protective Device (SPD). Designed for DC power systems, this surge protection device combines a 600V DC maximum continuous operating voltage with a 20kA nominal discharge current and 40kA maximum discharge current.

With its double-pole configuration and specified voltage protection level below 2.5kV, the TOMZN TZG40-PV is an option to consider for suitable solar PV and other DC electrical protection applications.

600V DC Maximum Continuous Operating Voltage

The TOMZN TZG40-PV features a maximum continuous operating voltage (Uc) of 600V DC.

This specification is important when selecting an SPD for a DC electrical system. The operating voltage of the installation must be compatible with the device's voltage rating.

2-Pole DC Surge Protective Device

This model features a 2P double-pole configuration for compatible DC electrical installations.

The two-pole design is intended for suitable DC circuit arrangements. Correct polarity, terminal connections, and wiring configuration must follow the manufacturer's installation instructions.

20kA Nominal Discharge Current (In)

The TZG40-PV has a specified nominal discharge current of 20kA with an 8/20µs waveform.

The nominal discharge current is an important parameter when evaluating the surge-handling capability of a protective device under the specified test conditions.

40kA Maximum Discharge Current (Imax)

The device supports a maximum discharge current of 40kA (8/20µs).

This specification indicates its stated maximum discharge-current capability under the specified waveform conditions. Proper SPD selection should also consider the installation's surge exposure, protection coordination, and manufacturer's recommendations.

Voltage Protection Level Below 2.5kV

The TOMZN TZG40-PV has a specified voltage protection level (Up) of less than 2.5kV.

This parameter indicates the stated voltage level associated with the SPD's protection performance. It is an important consideration when selecting surge protection for connected DC equipment.

Suitable Applications

Depending on the manufacturer's complete technical specifications and system requirements, the TOMZN TZG40-PV may be considered for:

• Solar PV DC protection systems

• DC electrical distribution panels

• Compatible solar inverter DC circuits

• Renewable energy installations
