The 4-pole configuration suits three-phase systems with a switched neutral, common in European and Asian panel designs where the neutral must be isolated during maintenance. The 20 A rating holds steady from 40 °C through 55 °C, then derates to 19 A at 60 °C and 19 A at 70 °C. For a panel running warm — say, 50 °C ambient — this breaker still delivers its full 20 A without a sizing penalty. Dimensions are 70 mm deep, 101.6 mm wide, 130 mm high — a standard 4-pole MCCB footprint that fits Siemens 3VA switchboard and distribution board cutouts. The IP40 front protection means it's suitable for enclosed panels where tools or fingers won't contact live parts during operation. Maximum power loss is 12 W at rated current — a modest figure that won't drive significant cabinet heating in a typical distribution board with natural convection.","metaTitle":"Siemens 3VA1120-6GE46-0AA0 SENTRON MCCB, 20A 4-Pole, 220kA a","metaDescription":"Siemens 3VA1120-6GE46-0AA0 SENTRON molded case circuit breaker, 20 A, 4-pole, TM220 release, 220 kA at 240 V AC.
