– finely stranded with end sleeve 2 x 0.5 up to 1.5 mm²;
1 x 0.5 up to 2.5 mm²
– single-wire 2 x 0.5 up to 2.5 mm²;
1 x 0.5 up to 4 mm²
Cable cross section, single or multi-stranded: 2 x AWG 20 up to 14
Tightening torque: 0.8 to 1.2 Nm
• Spring-loaded terminals (1 or 2 cables are connectable at each terminal)
– single-wire 2 x 0.25 up to 1.5 mm²
– finely stranded with end sleeve 2 x 0.25 up to 1.0 mm²
– finely stranded without end sleeve2 x 0.25 up to 1.5 mm²
Cable cross-section, solid or stranded: 2 x AWG 24 up to 16
The rated supply voltage U
s
(24 V DC) is applied at terminals A1(L+) and A2(M).
The terminals have degree of protection IP20 according to EN 60 529.
