Product Feature

- These circuit breakers are intended for the protection of circuits against overloads and short circuits in residential, commercial and industrial premises;

- It covers the rating range from 6 to 63A with a uniform breaking capacity of 6.5 kA throughout;

- Current-limiting scheme: in the event of a short circuit, are able to limit the let-through current to 60%-70%  of the rated current;

- The arc extinguishing system: allows the short-circuit currents of very high value to be interrupted extremely rapidly, the remarkable opening speed of contacts opening and the structure of the arcing chamber contribute to extinguishing the arc in the shortest possible time;

-The sensitivity and reliability of the trip mechanism ensures perfect closure every time,thereby considerably improving the performance of these devices and extending their average lifetime;

- The internal contact position allows an exact information of the circuit-breaker status:“green”, open contacts;“red”, closed contacts,independently of the toggle position;

- Sealing/locking sealable with 1 mm wire , to prevent unwanted  tripping;

- The supply lines of the protected circuit can be connected to either the upper or lower terminals of the circuit-breakers(reversibility of connections). The double terminal of these circuit-breakers enables simultaneous connection of cables and busbars.

My own musical tribute to two great men of science. Carl Sagan and his cosmologist companion Stephen Hawking present: A Glorious Dawn – Cosmos remixed. Almost all samples and footage taken from Carl Sagan’s Cosmos and Stephen Hawking’s Universe series.

RIP Dr. Sagan, you will be missed!!

This song is now out on 7″ vinyl through Jack White and friends at Third Man Records! Check it out here:

Lyrics:

[Sagan]
If you wish to make an apple pie from scratch
You must first invent the universe

Space is filled with a network of wormholes
You might emerge somewhere else in space
Some when-else in time

The sky calls to us
If we do not destroy ourselves
We will one day venture to the stars

A still more glorious dawn awaits
Not a sunrise, but a galaxy rise
A morning filled with 400 billion suns
The rising of the milky way

The Cosmos is full beyond measure of elegant truths
Of exquisite interrelationships
Of the awesome machinery of nature

I believe our future depends powerfully
On how well we understand this cosmos
In which we float like a mote of dust
In the morning sky

But the brain does much more than just recollect
It inter-compares, it synthesizes, it analyzes
it generates abstractions

The simplest thought like the concept of the number one
Has an elaborate logical underpinning
The brain has its own language
For testing the structure and consistency of the world

[Hawking]
For thousands of years
People have wondered about the universe
Did it stretch out forever
Or was there a limit

From the big bang to black holes
From dark matter to a possible big crunch
Our image of the universe today
Is full of strange sounding ideas

[Sagan}
How lucky we are to live in this time
The first moment in human history
When we are in fact visiting other worlds

The surface of the earth is the shore of the cosmic ocean
Recently we’ve waded a little way out
And the water seems inviting
