DC fuse holder for overcurrent protection
The ATK-RT132 fuse holder is designed for circuits with fuses with a rated DC voltage of up to 1000 V DC and a rated current of 16 A. It is used in series-parallel connection with photovoltaic panels and batteries, where it provides reliable protection against short circuits in charging converters and at the same time protects PV power plants, inverter and rectifier systems.
The fuses ensure a fast response to surge and short-circuit currents with a breaking capacity of up to 33 kA , significantly increasing the safety of the entire installation. The product complies with the national standard GB/T13539.6 and the international standard IEC60269-6 , which guarantees its high reliability and compatibility in modern photovoltaic systems.
Fuse (overcurrent protection)
The fuse insert is made of a silver strip with a variable cross-section, which guarantees precise and reliable current interruption when the rated value is exceeded . This strip is housed in a fuse case made of high-strength material, resistant to mechanical stress and thermal influences.
The case is filled with chemically treated high-purity silica sand, which, in combination with special chemicals , effectively dampens the electric arc that occurs when the circuit is disconnected. The fuse ends are spot-welded and firmly connected to the contacts, which ensures long-term stability, low contact resistance and safe operation even under demanding conditions of photovoltaic installations.
Surge protection T1+T2
The ATK-DC02 double-string DC Box surge protector is designed for DC photovoltaic systems with a rated operating voltage of up to 1000 V DC . It reliably protects PV panels, inverters and other components from impulse surges caused by lightning discharges or switching peaks.
- Class T1 ensures resistance to direct or close lightning strikes with very high energy
- Class T2 protects the system against more frequent switching surges and remote discharges.
- In combination, they provide comprehensive and long-term protection for the entire PV system.
The protection is characterized by a high discharge capacity of up to 40 kA (8/20 μs) , a short response time of 25 ns and a low protection level of only 1.8 kV . Thanks to a wide operating temperature range from -40 °C to +85 °C, it is suitable for long-term and reliable operation even in harsh conditions.
Durable design for outdoor use, quick and economical installation
Thanks to its robust construction and IP65 protection class, the device is reliably protected against dust, moisture and splashing water, which allows it to be used without any problems even in demanding outdoor conditions.

Single-pole DC box wiring diagram
The single-pole connection diagram of the DC Box ATK-DC02 shows the connection of two PV strings to a common distribution box. Each string is equipped with its own fuse (FU1 and FU2) that protects the circuit from overcurrent or short circuit, and a surge protector (FV1 and FV2) of type T1/T2 that effectively discharges surges caused by lightning strikes or switching spikes to ground via the protective PE conductor.
From each string , 2×SOLAR 6 mm² output wires then lead to the inverter, where the direct current is converted to alternating current . This connection ensures independent and reliable protection for both strings and contributes to the long-term stability of the entire photovoltaic system.
