Advantage 1 - Functional design
A concept with a future – design follows function
Elegant blue design
- Modern design
- User-friendly ergonomics
- Easy-to-understand product designation
- Clearly legible On/Off marking
ABL SURSUM miniature circuit breakers are so attractive because of their technology-oriented
design with elegant blue accents and a maximum focus on practical application. The product
range is exceptional due to its fully-developed concept in all product details.
Optimum user ergonomics
The centrally arranged handle is ergonomically optimised and ensures anti-slip-off and comfortable switching thanks to its
practical corrugation. The clear On/Off marking on the handle is clearly legible in every position.
All designations are easy to understand and clearly printed on the devices. Thus, there is no danger of confusion.
A clear advantage for more ease of use and ordering.
Advantage 2 -Compact construction
More space for wiring – when size is decisive only
- Minimum dimensions – with an installation height of 82.5 mm, one of the smallest miniature
circuit breakers on the market
- Maximum saving of space for comfortable wiring
Advantage 3 - Easier busbar removal
At ABL SURSUM, we know that there is little space for wiring in a small installation
distribution board. Every millimetre counts and creates advantages when installing.
Therefore, our miniature circuit breakers have a particularly compact design.
With an installation height of only 82.5 mm, they rank among the smallest devices on the
market. Thus a significantly larger wiring space is available. The extended
installation space allows for easy, comfortable and thus quick.
A clear advantage for more convenient mounting.
Simplify installations –increase efficiency
- Innovative fixing slides for easy removal from a busbar combination
- No laborious moving of the mounted miniature circuit breakers
- “singlefix” for removal from a bottomfixed busbar
- “twinfix” for removal from a busbar on both sides
Easier removal of circuit breakers for busbars at the bottom
ABL SURSUM has developed a new system for easier busbar removal – the fixing slide singlefix:
Ideal for removing the miniature circuit breaker from the lower busbar combination.
This allows for removing individual miniature circuit breakers of the S and SL range from a
bottom-fixed busbar – without any laborious moving.
Feasible with every standard busbar (busbars fork type).
In this way, electrical systems can be extended or modernized even more easily.
A clear advantage for more installation efficiency.
Easier removal of circuit breakers even for busbars at the top
- Innovative fixing slides for easy removal from a busbar
combination on both sides
- No more time-consuming moving required
in the field of industrial installation technology, maximum flexibility for
the highest requirements is often required. Quick mounting or replacing of miniature circuit
breakers is one of the most important prerequisites to keep downtimes at the lowest possible level.
For the T range, we have developed an innovative system of two fixing slides that
solves this problem perfectly: twinfix.
The two fixing slides enable removing from a busbar combination on both sides.
This makes it possible to remove individual miniature circuit breakers without difficulty.
Feasible with every standard busbar (busbars fork type).
A clear advantage for more installation flexibility.
Advantage 4 - Screwless terminal technology
Speed and safety – screwless terminal technology
- Innovative, screwless connection technology “plug2power”
- Quick mounting – easy removal
- Highest wiring safety
- Integrated test opening for voltage measurement
Quicker installation with “plug2power”
In present-day installation technology, saving time is an important competitive advantage. Our innovative, screwless terminal
technology “plug2power” makes this time saving possible. For “plug2power” connections, the
screw terminal at the upper output is replaced by a plug terminal with particularly high clamping force.
Safer installation with “plug2power”
Of course, our ABL SURSUM “plug2power” plug terminals are absolutely safe. In addition, their tensile load capacity is high and they are
maintenance free. Due to their special design, the terminals even allow higher tensile loads than screw terminals. An involuntary release is
practically impossible due to the self-correcting forces of the tension spring.
We have also considered the details for our “plug2power” technology: Measuring the voltage and releasing the connected conductor with a
screwdriver through the practical measuring opening.

Advantage 5 - Professional
- Optimal labelling concept for device marking
- Maximum communication safety
- Optically uniform, continuous labelling
ABL SURSUM miniature circuit breakers offer you all the options for individual and user-friendly labelling. The big transparent
labelling window can easily be opened and closed. It holds your labels securely. Nothing gets soiled. Best requirements for good
Simple communication: The “pictoplan” labelling sheet
Miniature circuit breakers are often not labelled because it simply takes too long. For this reason, we offer the
“pictoplan” labelling sheet with pre-punched labelling symbols. Simply remove the symbols and insert them into the labelling
window. Can be done quickly and looks perfect. Your customers will be pleased.
Another advantage for good communication.
Unlimited communication – the “pictoplan” labelling software.
If the labelling symbols are not sufficient, we offer you the newly-developed, cost-free “pictoplan”
labelling software. Theperfect solution for machine and switchgear manufacturers to label several switching circuits
individually with numbers and letters.
