It provides visible isolation for a circuit without overload or short-circuit protection — it's a disconnect, not a breaker. The integrated undervoltage release (24 V DC) drops the switch if control voltage is lost, and the auxiliary switch plus trip alarm switch give feedback for PLC or status lamp circuits. The 100 A continuous rating is the key selection number — it's sized for a 100 A feeder or branch disconnect. Clamp connections on the main circuit mean stranded or solid copper up to the terminal range, typical for panel feed-throughs. The undervoltage release at 24 V DC holds the switch closed; if the DC supply drops, the switch opens — common in emergency-stop chains or safety circuits where loss of control voltage must isolate the load. This mounts on the standard DIN rail in the enclosure. The IEC frame 160 footprint is a known size — 4-pole unit occupies roughly 140 mm width. Clamp terminals face forward, so wiring from the gland plate is straightforward. The undervoltage release coil draws from the 24 V DC bus; verify the power supply can handle the inrush when multiple releases are paralleled. The auxiliary and alarm switch terminals are separate — wire them to the PLC input card or a status indicator.","metaTitle":"SENTRON 3VA1110-1AA46-0BF0 Switch Disconnector, 100A, 4-Pole","metaDescription":"SENTRON 3VA1110-1AA46-0BF0 switch disconnector, 100A, 4-pole, IEC frame 160, with undervoltage release 24V DC, 1 aux switch, 1 trip alarm.
