Twenty amps, five hundred volts, and a window that says which way it is.

The indicator

Red and green, readable at a glance. Green means the breaker is in a normal closed state. That is the one thing a handle position cannot tell you — a breaker that tripped an hour ago and a breaker somebody switched off look the same from the handle.

The ratings

20 A, 500 V DC, two poles, 35 mm DIN rail. The four figures that place it.

The handle

C-shaped with a wide ergonomic curve, described for operation under load. On a DC isolator that is not decoration: opening a live string takes a firm, complete movement.

The lines this listing leaves blank

The breaking capacity. The other DC breaker in this catalogue gives 4.5 kA; this one gives nothing, and it is the rating that describes the worst case.

The trip curve. And the polarity — on DC, the direction the current flows decides how the arc is pushed into the chute.

Availability

German, French and Spanish Amazon stores quoted 15 € to 17 € when this page was compiled.

Italian Amazon store wanted more than 1.6× what the cheapest country wanted. A margin that wide usually means stock shipped in from elsewhere rather than a seller on the ground, so that quote stays out of the range above.

American and British Amazon catalogues carry an entry for it, with nobody selling.

These figures are what Keepa reported on the day this page was last updated. Availability and pricing move without notice.
