It is a 3-pole device, meaning it switches all three phases simultaneously, and it carries a maximum rated operational voltage of 690 V AC at 50/60 Hz or 500 V DC. The part is designed for busbar connection with front terminals, so it lands directly onto a panel's main distribution bus without extra adapters.
The 2 kA limited-time (0.5 s or 1 s) rating tells you the short-time withstand capability; this is a switch disconnector, not a breaker with a high interrupting rating, so it is meant for isolation and load switching, not fault clearing upstream of a breaker. The 690 V AC / 500 V DC max operational voltage covers most industrial distribution voltages, including 400 V and 480 V three-phase systems. The shunt trip release (STL) is included as standard — that is a voltage-triggered remote trip coil that lets a safety circuit or PLC force the disconnect open. No undervoltage release, no auxiliary contacts, and no communication module are fitted on this variant.
