The Siemens SENTRON 5TL1492-0 is a four-pole on/off switch disconnector designed for isolating AC electrical circuits. It provides four normally open contacts and is rated for an operational current of 125 A at up to 440 V AC, with a frequency range of 50/60 Hz and a short-circuit current rating of 10 kA.
Occupying four modular width units, the 5TL1492-0 measures 89.8 mm high and 74.5 mm deep, with a 70 mm installation depth. Its screw terminals accept rigid or flexible conductors from 2.5 mm² to 50 mm² and require a tightening torque of 2.5–3 N·m. The switch disconnector operates within an ambient temperature range of -5°C to 40°C and has a net weight of 443 g.
