Breaking capacity drops from 220 kA at 240 V to 154 kA at 415 V, then 121 kA at 440 V, and 17 kA at 500 V and 690 V — the steep drop above 480 V means this is primarily a 240 V / 480 V class device; for 690 V applications the available fault current must be verified against the 17 kA rating. The breaker measures 76.2 mm wide (3 in), 130 mm tall (5.12 in), and 70 mm deep (2.76 in) — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures with the appropriate SENTRON mounting accessories. Front IP40 protection means it is suitable for general-purpose indoor panels but not washdown areas. No undervoltage release or shunt trip is fitted as standard; those are add-on accessories if the safety circuit requires a remote trip. ## Approvals and Compliance Documentation As a Siemens SENTRON product, this MCCB carries CE marking for the European market and is designed to meet IEC 60947-2. UL and CSA listings are typical for the 3VA family, though specific certification details should be confirmed from the nameplate or factory certificate. RoHS and REACH compliance documentation is available from Siemens per standard industrial practice.","metaTitle":"Siemens 3VA1120-6ED36-0AA0 SENTRON MCCB, 20 A, 3-Pole, 220 k","metaDescription":"Siemens SENTRON 3VA1120-6ED36-0AA0 molded case circuit breaker, 20 A rated, 3-pole, line protection.
