Description
Fuse terminal block, 281 Series, grayOur fuse terminal block (item number 281-612/281-541) ensures effortless electrical installations. Conductors should only be connected to this fuse terminal block if their strip length is between 9 and 10 mm . Featuring conductor terminals along with CAGE CLAMP®, this product delivers reliable performance. Our CAGE CLAMP® connection offers a safe and maintenance-free way to connect all types of conductors. You do not need to prepare the conductor in any way, such as crimping ferrules. This fuse terminal block is suitable for conductor cross sections ranging from 0.08 mm² to 4 mm².

Electrical data - Ratings per IEC/EN – Notes
| Ratings (note) | Electrical ratings are given by the fuse and blown fuse indication. |
|---|---|
| Rated current (note) | Leakage current in case of a blown fuse: LED 6 mA |
Electrical data - Power Loss
| Power loss (max.) P<sub>l (max.)</sub> (note) | When selecting glass cartridge fuses, make sure that the maximum power loss listed below is not exceeded. The power loss is determined according to IEC or EN 60947-7-3/VDE 0611-6 at 23°C. The temperature rise of the terminal block must be checked according to their application and mounting. Higher ambient temperatures represent an additional impact on miniature fuses. Therefore, in such applications, the rated current must be reduced if necessary. More details are available from the manufacturers. |
|---|---|
| Maximum power loss P<sub>loss</sub> of fuse insert for overload and short-circuit protection (individual arrangement) | 2.5 W |
| Maximum power loss P<sub>loss</sub> of fuse insert for overload and short-circuit protection (block arrangement) | 1.6 W |
| Power loss P<sub>l</sub> max. short-circuit protection (individual arrangement) | 4 W |
| Power loss P<sub>loss</sub> (max.) of fuse cartridge for short-circuit protection (block arrangement) | 4 W |

| Connectable conductor materials (note) | Terminating Aluminum ConductorsWAGO Spring-Clamp Terminal Blocks are suitable for solid aluminum conductors up to 4 mm²/12 AWG if WAGO “Alu-Plus” Contact Paste 249-130 is used for termination.“Alu-Plus” Contact Paste Advantages:Automatically destroys the oxide film during clamping.Prevents fresh oxidation at the clamping point.Prevents electrolytic corrosion between aluminum and copper conductors (in the same terminal block).Provides long-term protection against corrosion.Using terminal blocks with CAGE CLAMP® Spring Pressure Connection Technology, aluminum conductors must first be cleaned with a blade and then immediately inserted into the clamping units filled with “Alu-Plus” contact paste.It is also possible to apply WAGO “Alu-Plus” additionally on the whole surface of the aluminum conductor before termination.Please note that the nominal currents must be adapted to the reduced conductivity of the aluminum conductors:2.5 mm² = 16 A4 mm² = 22 A |
