160 A MCCB with TM210 release — what the ratings mean for your panel
The Siemens 3VM1116-4ED22-0AA0 is a SENTRON molded case circuit breaker (MCCB) in a 2-pole, line-protection configuration. It carries a 160 A continuous rating at 40 °C, and the thermal derating is shallow — still 160 A at 50 °C, then 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. That means in a warm panel you lose only 10 A from 40 °C to 70 °C, so the breaker holds its rating well in tight enclosures. The TM210 overcurrent release is a thermal-magnetic type with a fixed thermal pickup and an adjustable magnetic trip set to 1600 A (10× In). The LI protection characteristic (long-time and instantaneous) covers cable and busbar protection in distribution panels. No ground-fault monitoring, no communication module, no motor drive option — this is a straight line-protection breaker for fixed-trip applications.
Breaking capacity — S-class at 240 V and 415 V
Rated breaking capacity hits 121 kA at 240 V AC and 76 kA at 415 V AC. That's the S switching capacity class — high enough for most industrial main or sub-feed applications where fault current is stiff. The 2-pole format with 250 V DC max (Ue DC) means it also handles DC circuits up to that voltage, though the DC breaking values are covered in the separate 3VA manual.
Panel fit and integration
Footprint is 50.8 mm wide (2 in), 130 mm tall (5.1 in), 70 mm deep (2.8 in). That's a compact 2-pole MCCB — fits standard DIN-rail or panel-mount enclosures where a 50 mm wide slot is allocated. IP40 on the front means dry indoor panels only; no washdown rating. The neutral conductor is not upgradeable or retrofittable, and there are zero auxiliary contact COs on this variant.
