The 4-pole configuration (3 phases + neutral) makes it suitable for three-phase four-wire systems where the neutral needs switching and protection. At 240 V it interrupts 52.5 kA; at 415 V that drops to 32 kA; at 440 V it is 13.6 kA; and at 500 V or 690 V it holds at 7.5 kA. For a 20 A frame, those are high-interrupting ratings — the breaker can sit upstream of smaller branch breakers in a distribution panel and still coordinate. The 52.5 kA at 240 V is typical for North American 240/120 V split-phase service entrance or large subfeed applications. Thermal derating matters when the breaker lives in a warm enclosure. The 3VA1020-2ED46-0AA0 carries its full 20 A up to 55 °C ambient. At 60 °C it derates to 19 A, and it holds 19 A through 70 °C. Simple, reliable, and what you want when the BOM calls for a basic MCCB with no auxiliary electronics. ## Panel fit and physical integration Dimensions: 130 mm height, 101.6 mm width, 70 mm depth. The 101.6 mm width (4 inches) is the standard 4-pole MCCB footprint in the 3VA frame — it occupies the same panel cutout as any other 4-pole 3VA breaker of this frame size. Depth of 70 mm (2.76 in) is shallow enough for most distribution boards; no special enclosure depth needed. IP40 on the front face means protection against tools and small wires entering the front, but the breaker is intended for enclosed installation inside a panel. The 800 V insulation rating means it is suitable for 690 V AC systems with margin — common in industrial panels feeding 690 V motors or transformers. The DC rating to 600 V opens the door for battery or UPS applications, though the DC breaking capacity must be verified per the 3VA DC manual (referenced in the device manual). ## Comparison: 3VA1020-2ED46-0AA0 vs 3VA1020-3ED36-0AA0 The closest functional peer is the 3VA1020-3ED36-0AA0. Both are 4-pole 20 A SENTRON MCCBs in the same physical frame (same height, width, depth). The difference is the release type: the -2ED46-0AA0 carries a TM210 thermal-magnetic release; the -3ED36-0AA0 carries a TM240 release. The TM210 has a fixed thermal pickup at 20 A with magnetic trip adjustable from 160 A to 320 A. The TM240 has a different magnetic adjustment range. For most line-protection applications where you just need a 20 A breaker with standard magnetic pickup, the TM210 is the simpler, more commonly stocked variant. The -3ED36-0AA0 would be chosen only if your coordination study specifically calls for the TM240's magnetic settings. Panel cutout and wiring are identical — no rewiring needed to swap between them.","metaTitle":"Siemens 3VA1020-2ED46-0AA0 SENTRON MCCB, 20 A, 4-Pole, TM210","metaDescription":"Siemens 3VA1020-2ED46-0AA0 SENTRON 4-pole MCCB, 20 A rated, TM210 thermal-magnetic release, 52.5 kA at 240 V.
