The TM220 thermal-magnetic trip unit provides adjustable overload protection from 112A to 160A (Ir), and fixed short-circuit protection at 10 times the rated current (Ii=10 x In). ## DC Power OEM variant — nut keeper kit The -ZD00 suffix flags this as a special variant built for a DC Power OEM in China, including a nut keeper kit. That kit prevents the terminal nuts from backing off under vibration or thermal cycling — a common failure point in high-current DC bus connections where loose hardware generates arcs. If you're replacing a standard 3VA1 in a DC power cabinet, confirm the nut keeper kit matches your bus bar hole pattern; the rest of the breaker — frame, trip, breaking capacity — is identical to the catalog 3VA1216-4EE32-0AA0. For volume or project pricing, send the RFQ with target quantity and delivery window. The nut keeper kit variant may have different MOQ than the base catalog breaker — we'll confirm at quote.","metaTitle":"Siemens 3VA1216-4EE32-0AA0-ZD00 MCCB, 160A, 36kA @ 415V","metaDescription":"Siemens 3VA1 IEC frame 250 MCCB, 3-pole, In=160A, Icu=36kA @ 415V, TM220 overload 112-160A, short-circuit Ii=10xIn.
