DAH Series
Tyco Electronics’ Bowthorpe EMP
business group pioneered the
development of polymeric composite
housed surge arresters in
the early 1980’s and since then has
proven service expe rience across
the globe, operating in the world’s
toughest environments. DA Series
surge arresters provide active over
voltage protection that contributes
directly to improved reliability of
your system, reducing lost minutes
and protecting expensive assets.
Tyco Electronics Bowthorpe EMP
DA silicone surge arresters have
been designed and tested to meet
customers’ demand for reliability
and improved operational performance.
DA development was based
on 30 years of experience in arrester
design and manufacturing within the
Tyco Electronics Energy Division.
The DAH series is qualified to the latest
revision of IEEE C62.11, (2005) and all
reports are independently certified.

Sealing:
All arrester cores are encapsulated in silicone insulating
housing. A permanent chemical bond connects the
arrester core and the non-tracking silicone housing. This
invisible interface prevents moisture from entering during
severe thermal fluctuations due to normal climatic and
energy absorption events. |

Polymer housing:
Non-tracking and hydrophobic silicone insulating material
is used for DA arrester housings. The DA surge arrester
series is available with standard or extra leakage distance.
The housing material has proven performance in long
term TERT and UV aging tests and proven resistance
to flammability. |

|
Integrated design:
Manufacturing integrates all components in a single
piece. There are no glued interfaces. The design is void
and gap free ensuring peak performance under the
harshest conditions. |

Reliable and consistent GLD
The robust ground lead disconnect (GLD) offers
operational reliability and consistency. It was designed
to operate in event of arrester failure, removing ground
connection and fault from line. It can be shipped and
stored restriction free. |

Safe mode of failure:
Our high energy arresters are tested in accordance with
the short circuit mode of failure test in IEEE C62.11, (2005).
This testing has proven the DAH’s safe and predictable
failure characteristics. |

Quality:
The DAH series arrester is manufactured to international
quality standards in Tyco Electronics production facilities.
We perform 100% routine testing on arresters:
1) Visual inspection
2) Reference voltage test
3) Power loss test
4) Partial discharge test
