<strong>Reliable</strong> Protection <strong>and</strong> Switching<br />
For Electric <strong>and</strong> Hybrid Vehicles
<strong>Reliable</strong> <strong>technology</strong> <strong>for</strong> <strong>high</strong> <strong>DC</strong> <strong>voltages</strong><br />
HV<strong>DC</strong> <strong>relays</strong> <strong>and</strong> circuit breakers <strong>for</strong> <strong>DC</strong> 48 V<br />
In electric mobility the focus is on <strong>high</strong><br />
voltage systems with <strong>DC</strong> 450 V, <strong>DC</strong> 650 V<br />
<strong>and</strong> even <strong>DC</strong> 720 V. But sub-systems with<br />
<strong>DC</strong> 48 V have again become a topical<br />
subject. The automotive circuit breaker<br />
type 1170 can be used at 48 V <strong>DC</strong> <strong>and</strong> is<br />
there<strong>for</strong>e suitable <strong>for</strong> the design of<br />
sub-systems.There is also a 48 V version<br />
available of our power <strong>relays</strong> PR60 <strong>and</strong><br />
PR80.<br />
For <strong>high</strong> voltage applications E-T-A<br />
provides well-proven circuit breaker<br />

Versions up to 400 V <strong>DC</strong> are possible.<br />
A patent application has been filed <strong>for</strong> the<br />
<strong>technology</strong> of the newly designed HV<strong>DC</strong><br />
relay which operates without vacuum or<br />
inert gas, provides identical per<strong>for</strong>mance<br />
in both directions <strong>and</strong> is capable of<br />
disconnecting <strong>high</strong> inductive loads.<br />
Patent is also pending <strong>for</strong> the arc extinction<br />
<strong>technology</strong> which will enhance the typical<br />

life of <strong>relays</strong> considerably with <strong>voltages</strong> of<br />
<strong>DC</strong> 24 V plus. Electronic extinction of the<br />
arc in a mechanical contact can increase<br />
the max. number of cycles at rated load<br />
to equal mechanical endurance of the<br />
relay even with inductive loads.<br />
