ANTIK AC Box AC01 3-phase is a 3-phase AC distribution box designed for on-grid and off-grid photovoltaic systems. It connects the inverter to the grid and the backup circuit and, thanks to integrated elements, ensures stable and safe operation of the entire installation.
It contains a combined surge module ATK-SPDE40 of class T1+T2+T3 (B+C+D), which protects all phases and the neutral conductor. The SPD can handle impulse currents up to 20 kA and limits surges to 1.5 kV. The circuit breaker F1 (ONGRID) protects the network branch and F2 (BACKUP) separately insures the output for the backup circuit.
The housing is made of UV-resistant plastic with IP65 protection, suitable for long-term outdoor operation. The device is rated for temperatures from –40 °C to +85 °C and has dimensions of 295 × 250 × 140 mm , which allows for compact installation.
Reliable surge protection for on-grid and off-grid solutions
ANTIK AC Box AC01 3-phase is designed as a professional solution for the protection of 3-phase hybrid inverters in on-grid and off-grid photovoltaic installations. It ensures stable operation, a high level of safety and a long service life of the entire PV system. Thanks to its compact design and prefabricated construction, it is suitable for quick connection by qualified electricians, whether in households or in smaller commercial operations.
Key benefits:
- Circuit breaker rating: 16 A at 400 V
- Integrated 4-pole surge protection (for 3 phases + N conductor)
- Protection classes T1+T2+T3 (B+C+D) for comprehensive surge protection
- IP65 protection – dust and water resistance, designed for outdoor use
- Optimized design for quick and safe installation by professionals
Internal layout and functional division
The AC Box AC01 3-phase is designed with a clear division of elements, which facilitates service, inspection and future expansion of the system. The internal layout is optimized for a safe and logical connection between the inverter, the distribution network and the backup circuit.
F1 – Branch circuit breaker “ONGRID”
It serves to protect the connection to the distribution network. It allows for quick and safe disconnection in the event of maintenance or failure.
F2 – “BACKUP” branch circuit breaker
It independently protects the output for the backup circuit, powered by the hybrid inverter, in the event of a power outage. It ensures separation and safe operation of the backup source.
FV1 – Integrated surge protection SPD (ATK-SPDE40)
Combined multi-pole surge module of type T1+T2+T3 (B+C+D). It has four protective terminals – three for each phase (L1, L2, L3) and one for the neutral conductor (N-PE). This system provides complete protection of a three-phase network against impulse currents up to 20 kA and surge peaks with a protection level of 1.5 kV.
Advanced surge protection (T1/T2/T3)
The device is equipped with multi-stage surge protection that combines classes T1, T2 and T3 (B+C+D). This combination ensures complete system protection against all types of surge events – from strong impulses caused by lightning strikes (T1), through surges transmitted by the network (T2), to subtle voltage spikes threatening electronics (T3).
Thanks to integrated protection, not only the hybrid inverters themselves are protected, but also the connected devices, which extends the life of the entire PV installation and reduces the risk of failure.
Technical parameters of surge protector
- Impulse current: up to 20 kA
- Voltage protection level (Up): 1.5 kV
- Protection class: T1 + T2 + T3 (B+C+D)
- Configuration: 4-pole (protection L1, L2, L3 and N-PE)
Unified protection for the entire three-phase circuit
The switchboard has a 4-pole surge protection (L1, L2, L3 + N), which ensures comprehensive protection of the entire three-phase PV system. This approach protects not only the hybrid inverter itself, but also all devices connected to the common network , thereby minimizing the risk of damage to sensitive components during surges.
- 4-pole surge protector: L1, L2, L3 + N
- Unified protection for the entire three-phase circuit
- More stable wiring – fewer separate protection elements
- Increased safety and reliability of the PV system
Durable design for outdoor use
The design of the device is designed for long-term and reliable operation in outdoor environments. The construction of the UV-resistant plastic ensures that the cover retains its mechanical strength even with long-term exposure to sunlight and extreme weather conditions . The switchboard is resistant to moisture, dust, snow and sudden temperature changes, which guarantees stable protection of electrical components throughout the year.
