It is built in MCCB design but configured as a dedicated disconnector — no overload or short-circuit protection elements onboard. That means it serves as a manual load-break isolator for a 160 A circuit, not as a circuit breaker. The 160 A rating sets the maximum uninterrupted current the main contacts can carry; the switch is intended for infrequent switching of loads under rated conditions, with a mechanical latching endurance of 15,000 operations. Rated insulation voltage Ui is 800 V, and the maximum operational voltage is 690 V AC (50/60 Hz) or 500 V DC.
The 3VA1116-1AA36-0HC0 occupies a 76.2 mm wide footprint on the DIN rail or panel-mount surface, with a depth of 70 mm behind the panel and a height of 130 mm. The front terminal arrangement keeps the main power conductors accessible from the front, which simplifies wiring in a dense panel layout. An optional motor drive can be added for remote motorized operation.
