Product details

The SENTRON 3VA1116-1AA32-0CA0 is a 3-pole switch disconnector from the 3VA1 IEC frame 160 series, rated at 160 A continuous without overload or short-circuit protection — it's a pure disconnect, not a breaker. It carries an undervoltage release (UVR) for 120-127 V AC 50/60 Hz, so if control voltage drops, the switch opens automatically.

Compared to the 3VA1112-5EF32-0CA0 — a line-protection MCCB with thermal-magnetic trip — this 3VA1116-1AA32-0CA0 has no overcurrent release, no short-circuit protection, and no trip indicator. If your BOM calls for a disconnect-only device with UVR, this is the one. If you need integrated protection, the 3VA1112-5EF32-0CA0 is the breaker variant.

Mounts in a standard panel enclosure with front terminals and busbar connection for the main circuit. The 76.2 mm width fits a 3-pole frame on DIN rail or direct panel mount. IP40 on the front keeps dust out in a clean control cabinet. Ambient operating range -25 °C to 70 °C; above 55 °C the continuous current derates from 160 A down to 150 A at 70 °C — factor that into your busbar sizing.

Frequently asked questions

Where can I buy 3VA1116-1AA32-0CA0?

Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.

What is the closest functional second-source to 3VA1116-1AA32-0CA0?

The 3VA1112-5EF32-0CA0 is the same frame and footprint but it's a molded case circuit breaker with thermal-magnetic overcurrent protection — not a pure disconnect. For a disconnect-only with UVR, this 3VA1116-1AA32-0CA0 is the specific variant.

Will 3VA1116-1AA32-0CA0 drop into a panel specified around 3VA1112-5EF32-0CA0 without rewiring?

Yes — same frame dimensions (70 mm deep, 76.2 mm wide, 130 mm high) and both use front terminal busbar connection, so mechanical fit and busbar alignment are identical. The wiring difference is that the 3VA1116 has no auxiliary contacts and no overcurrent trip wiring.
