It is a 3-pole device designed for isolation and switching duty — no overload or short-circuit protection built in, so it functions purely as a disconnect, not a protective breaker. Above that, derating is gradual: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. That 150 A floor at the maximum operating temperature of 70 °C means the part holds 94% of its nominal rating at the top of the ambient range — useful for panels with poor airflow or high ambient heat from adjacent drives. ## Integration notes The 3VA1116-1AA32-0DH0 occupies a 3-pole MCCB footprint: 130 mm height, 76.2 mm width, 70 mm depth. Front terminals accept busbar connection — no lug kit needed if the panel uses a busbar feed. The UVR coil draws from a 208-230 V AC control circuit; verify the control transformer taps before energizing. The auxiliary contact block provides 3 CO contacts total (2 aux + 1 trip alarm), all HQ-rated. Mechanical life is 15,000 operating cycles typical. Optional motor drive available as a field-addable extension. ## What it is not — and why that matters for your BOM This is a switch disconnector in an MCCB housing, not a molded-case circuit breaker. It has no overcurrent release — no thermal-magnetic or electronic trip unit inside. If your BOM calls for a 3VA1 MCCB with overload and short-circuit protection (like the 3VA1110-5EF32-0AM0, which carries a TM240 release and 100 A frame), this part will not provide that protection. The 3VA1116-1AA32-0DH0 is the disconnect-only variant: same frame, same footprint, same auxiliary wiring scheme, but no trip curve. Use it where the upstream breaker or fuse already handles protection and you just need a local disconnect with status signaling.","metaTitle":"Siemens 3VA1116-1AA32-0DH0 SENTRON Switch Disconnector, 160","metaDescription":"Siemens 3VA1116-1AA32-0DH0 SENTRON switch disconnector, 160 A at 40 °C, 3-pole, with undervoltage release 208-230 V AC.
