Its job is safe isolation under load, not fault interruption. The 4-pole configuration switches three phases plus neutral, which matters for TN-S or TN-C-S systems where you need full isolation of the neutral conductor. Rated insulation voltage is 800 V, with maximum operational voltage 690 V AC 50/60 Hz and 600 V DC. That DC rating is useful for 480 VDC bus applications common in data-center or solar-string isolation. ## Built-in auxiliary and release package This variant ships with an integrated undervoltage release (UVR) rated 208-230 V AC, plus two HQ auxiliary switches and one HQ trip alarm switch — three CO contacts total. The UVR ensures the disconnector opens automatically if control voltage drops, a standard requirement for safety isolation in conveyor or machine-tool circuits. The auxiliary and alarm contacts feed status back to a PLC or panel indication without needing separate add-on modules. The main current circuit uses busbar connection on front terminals — designed for direct busbar stabs or bolted link bars, not lug or box terminals. That means the panel bus must be planned around this connection style; retrofitting into a lug-terminated panel requires an adapter kit. Optional motor drive is supported for remote switching. ## Mechanical and environmental limits Mechanical endurance is rated at 15 000 operating cycles — typical for a switch disconnector in this frame class, suitable for daily isolation duty but not for frequent switching as a load-break device.","metaTitle":"Siemens 3VA1116-1AA42-0DH0 Switch Disconnector, 160 A, 4-Pol","metaDescription":"Siemens SENTRON 3VA1116-1AA42-0DH0 switch disconnector, 160 A rated continuous current, 4-pole, 690 V AC / 600 V DC.

The MCCB has interrupting ratings up to 187 kA at 240 V; the disconnector has no SCCR because it is not designed to clear faults. They share the same 70 mm depth and 130 mm height, but the disconnector is wider at 101.6 mm vs 76.2 mm for the 3-pole MCCB.
