Fuse terminal blocks RSP

Application

The structure of these terminal blocks allows inserting a fuse element into the circuit - a tube protective fuse that is inserted into the tilted holder between the conductive contacts. The range of possible connectible conductors is from 0,5 mm2 to 6 mm2.The fuse terminal blocks of all offered types can be classified into the circuits either with alternating, as well as direct voltage. The terminal block can be fastened to DIN rails TS 15, TS 35x7,5, TS 35x15 and TS 32. The recommended position during an assembly of horizontally placed terminal blocks is such that the fuse holder is tilted downwards

Design

In the fuse terminal blocks, screws are used with a combined head of the screw - a screwdriver with a flat blade or cross type PH can be used. The material of the screw is steel, hardened, galvanic surfaced ZnCrCo. During the application of the recommended tools and tightening torque, the supplier will guarantee the resistance of the screw against damage even in the case of several applications. The material of the insulating body is polyamide PA 6, inflammability V0  according to UL 94, halogen-free. The electric conductive part is brass, galvanic-nickel, the contact part is tin-bronze.  It is possible to clamp the terminal blocks to TS 15, TS 35x7,5, TS 35x15 and TS 32 DIN rails

Specifics by the application of terminal blocks with  LED

These terminal blocks can find application in circuits where by the fuse interruption the circuit that powers the LED diode, stay closed through connected load (e.g.  a inductor relay, contactor, etc.). This state is signaled by alight of LED diode. The circuit is therefore not galvanic disconnected. If the circuit is interrupted at the same time with the fuse interruption, the LED diode will not be lit.  By direct voltage it is necessary to keep the polarity of the positive pole, marked on the terminal block.

Protection against injury from electric current

The coverage of the fuse terminal blocks is IP 20. In the case of an opened fuse holder, the coverage of the parts under voltage is IP 10.

Interconnection

In the row of the neighbouring terminal blocks, it is possible to mutually interconnect by plug-in bridges, it is not possible to interconnect by screw connecting units as basic terminal blocks.
