275V Three Phase Type 2 Surge Protection Device TUV Certificated BR275-40 3+1
- Class II / Type 2 lightning protective device.
- Consisting of a base part and 4 MOV plug-in protection modules.
- For using in the lightning protection zones concept at boundary 1-2.
- The core parts are metal oxide vristor components with high discharge capacity.
- Low residual voltage and quick response
- Reliable control thanks to Thermo Dynamic Control disconnector.
- With remote signaling contact for control device.
- Fault indication via red mark in the inspection window.
- Protection mode: L/N-PE.
Being total current arresters between the neutral and protective conductor in TT systems, the single-pole N-PE
lightning current arresters of type BR275-40 help to ensure fulfilling the requirements for protection of personnel
and equipment in "3+1" circuits. The Epcos discharge spark gaps were specifically used to meet this challenge.
With a discharge capacity up to 40 kA (10/350 μs), they fulfill the most stringent requirements of national and
international lightning protection standards. Their leakage-current-free spark gap design allows the devices to
be used upstream of the meter panel .
The BR275-40 coordinated NPE lightning current arresters hold a special position among total current arresters.
Due to their low voltage protection level, they can be directly coordinated with N-PE surge arresters of the BR275-40
surge arresters without additional decoupling coil. If lightning current arresters are to be installed along with surge
arresters at the same location, no additional coil is required thanks to the low voltage protection level of BR275-40.
The design and installation of BR275-40 arresters are adapted to the unique nature of low-voltage switchgear
installations and entirely complement the use of BR275-40arresters.
The multifunctional terminals of the DIN rail mounted BR275-40 devices are suitable for connecting conductors
and busbars, allowing comfortable wiring with other DIN rail mounted terminals.
