Strong connections in the proven screw connection system!
Everything for classic wiring in the screw connection system - even for high currents: from SRK feed-through and protective conductor terminals to RK high-temperature variants for conductor cross-sections from 0.2 mm² to 240 mm². The classic: proven - safe - reliable..
SRK screw connection system
The tried-and-tested terminal blocks in the screw connection system with a minimum cross-section of 0.08mm2 to 120mm2 are available in feed-through and protective conductor terminal block versions. The easy-to-use screw connection element enables rigid and flexible conductors with and without ferrules to be connected safely and quickly. To ensure mechanical and electrical safety, the PE foot contact on all PE conductor terminals is designed with screwless latching on both sides and up to a cross-section of 35 mm².
Compact and contour-matching
The external geometry of the SRK feed-through and SSL protective conductor terminals is identical for cross-sections of 2.5 mm², 4 mm², 6 mm² and 10 mm². Standardised end plates and partition walls are therefore possible. The overall width is 2.5 mm² (5 mm), 4 mm² (6 mm), 6 mm² (8 mm) and 10 mm² (10 mm). Despite their compact design, SRK feed-through terminal blocks offer a rated voltage range of up to 1000 V.

Fuse disconnect terminals SSIK 4 | SSIK 6
The SSIK fuse disconnect terminal blocks made of glass fibre-reinforced polyamide PA 6.6 V-0 offer interesting application possibilities in electrical engineering thanks to the extended temperature range of the housing material up to 140 °C (RDI Elec). They are characterised by good dimensional stability at elevated temperatures. The terminal blocks have a hinged disconnect lever that locks in the end position and can accommodate a spare fuse on the side. Two cross-connection channels within the fuse disconnect terminals enable potential distribution to neighbouring SRK series fuse and feed-through terminals.
Test disconnect terminals SPTK
SPTK test disconnect terminal blocks are primarily used in the field of electricity generation and electricity supply. They are tailored to the diverse switching requirements of current transformer secondary circuits. When replacing measuring instruments, electricity meters and for comparative measurements, current transformers must always have a closed secondary circuit. All versions are safe to touch in accordance with DGUV regulation 3. The current or voltage paths are separated by means of a captive, screwable isolating slide. The switch position is easily recognisable at all times as the disconnecting screw has a yellow insulating sleeve.
