SENTRON 3VA1120-4ED22-0AA0 — 20 A, 2-Pole MCCB with TM210 Release
Rated 20 A continuously at 40 °C, it derates to 19 A at 60 °C and holds that level through 70 °C — the full operating range of the breaker. Interrupting capacity reaches 121 kA at 240 V AC and 75.6 kA at 415 V AC, giving headroom for high-fault panels without cascading upstream.
Panel Fit and Integration
Two-pole footprint at 50.8 mm wide, 130 mm tall, 70 mm deep — fits standard DIN-rail or panel-mount enclosures with matching cutouts. Front face carries IP40 protection; the breaker is designed for line protection without communication, undervoltage release, or ground-fault monitoring.
Electrical Ratings and Duty
Rated insulation voltage is 500 V; operating voltage is 415 V AC or 250 V DC. Maximum power loss is 8 W. The TM210 release provides fixed thermal and magnetic trip settings for standard motor and distribution protection without adjustment.
