It carries a TM210 thermal-magnetic trip unit, meaning the thermal element handles overloads and the magnetic element clears short-circuits — no electronic adjustments, just reliable bimetal-and-solenoid operation. At 40 °C it is rated for 100 A continuous, and the 4-pole construction (switching all three phases plus neutral) makes it a natural fit for TN-S or TN-C-S systems where the neutral needs overcurrent protection. Breaking capacity is the headline number for any MCCB, and this one delivers 187 kA at 240 VAC, 121 kA at 415 VAC, and 75.6 kA at 440 VAC. Those figures mean it can safely interrupt a fault current up to 187 kA without welding contacts or rupturing the case — critical for high-fault installations near large transformers or in heavy industrial grids. At 500 V and 690 V the rating drops to 17 kA, so verify the available fault current at your system voltage before specifying. ## Thermal derating — the real continuous current The 100 A rating holds flat from 40 °C up to 50 °C. Above that, derating kicks in: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. If this breaker sits in a non-air-conditioned enclosure near other heat sources, use the 70 °C column for your ampacity calculation — 91 A is the safe continuous limit in that environment. The maximum power loss of 25 W also feeds into enclosure thermal rise calculations. ## Physical fit and panel integration The case dimensions are 130 mm high, 101.6 mm wide, and 70 mm deep. It mounts on a DIN rail or directly to a backplate via the standard MCCB footprint. The IP40 rating on the front means it is protected against tools and solid objects larger than 1 mm — fine for a closed panel, but not for washdown areas. No undervoltage release, no communication function, and no ground-fault monitoring on this variant; it is a straight thermal-magnetic line-protection breaker.","metaTitle":"Siemens 3VA1110-5ED46-0AA0 SENTRON MCCB, 100A, 4-Pole, TM210","metaDescription":"Siemens 3VA1110-5ED46-0AA0 SENTRON molded case circuit breaker, 100A at 40°C, 4-pole, TM210 trip unit, 187 kA at 240 VAC.

The -5ED46 variant carries a higher breaking capacity at 240 V (187 kA vs the -5ED32's lower rating), so it is a functional superset — it will physically fit and electrically replace the lower-rated unit without rewiring, provided the available fault current does not exceed the lower breaker's rating."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1110-5ED46-0AA0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3VA1110-5ED46-0AA0 when reusing this data.
