Your advantages
More space in control cabinets thanks to only 8 mm overall width
Simple application setup due to bridging option to CLIPLINE complete terminal block system
Transparency regarding the utilization and status of the system thanks to integrated connections for individual or collective signals
Easy commissioning and maintenance thanks to pre-installable wiring that remains untouched when replacing the connector
Frequently asked questions
How does the feed-in work and how is the bridging carried out?
Currents of up to 40 A can be fed in at the upper terminal point. Conductors with up to 6 mm2 flexible or 10 mm2 rigid can be connected. The current fed in can be distributed via the bridge shafts arranged at the top with FBS ..... View more
Currents of up to 40 A can be fed in at the upper terminal point. Conductors with up to 6 mm2 flexible or 10 mm2 rigid can be connected. The current fed in can be distributed via the bridge shafts arranged at the top with FBS ...-8 bridges. The following applies: currents greater than 31 A must be distributed via two bridges; currents up to and including 31 A can be distributed via one bridge.

Two different characteristic curves are available:
- The faster F2 characteristic curve is suitable for more sensitive loads, such as sensors or resistive loads. It triggers at DC voltages in the 4 ... 8 x In range.
- The medium-lag M1 characteristic curve is recommended for more current-intensive (e.g. capacitive) loads or motors. It triggers at DC voltages 8 ... 15 times In.
Are there requirements for the PS? What needs to be considered for correct dimensioning?
For selective protection, the power supply should be able to supply the necessary increased tripping current. Line impedances must also be taken into account.
What is meant by short-circuit breaking capacity and what is the difference between the terms Icn and Inc?
Short-circuit breaking capacity: Maximum short-circuit current that the circuit breaker can safely switch off. What must be observed if the source current is higher than the short circuit breaking capacity? In this case, the protective circuit breake... View more
Short-circuit breaking capacity: Maximum short-circuit current that the circuit breaker can safely switch off. What must be observed if the source current is higher than the short circuit breaking capacity? In this case, the protective circuit breaker may be used with a backup fuse up to the Inc. Certain fuses have been tested and approved for this purpose (see certificate).
- Icn (rated short-circuit breaking capacity): Value that the circuit breaker alone can switch off without backup fuse.
- Inc (Conditional rated short-circuit current): Value that the switch can handle with an upstream fuse.
Can the PTCB TM be used for AC and DC?
Yes, for AC the prospective short-circuit current at the intended installation location must be taken into account. This must not exceed the breaking capacity of the PTCB TM. The magnetic tripping for AC and DC differs by the factor DC/AC = 1.3.
