Two poles, five hundred volts, and a breaking capacity.

The figure that distinguishes it

4.5 kA. That is the fault current the breaker will interrupt and survive — the rating that says what happens on the worst day rather than on an ordinary one. Two DC breakers in this catalogue; one publishes it.

The ratings

16 A at 500 V DC, two poles. Stated plainly in the title and confirmed in the second bullet.

The construction

A flame-retardant, non-combustible housing with copper internals, described in the third bullet.

The mounting

A distribution box or 35 mm DIN rail, with screw terminals.

Trip curve and polarity, both unstated

A trip curve. “Highly sensitive with a fast response” is an adjective, and a curve — B, C or D — is what tells you whether an inverter can start behind it without tripping it.

And any polarity marking. On a DC breaker the direction of current decides how the arc is blown into the chute, and a breaker wired backwards clears a fault worse than one wired correctly.
