Continuous current holds flat at 320 A from 40 °C through 50 °C, then derates to 292 A at 70 °C — meaning the breaker can be applied near its nameplate rating in most ventilated enclosures without oversizing. The breaker measures 138 mm wide, 248 mm tall, and 110 mm deep — a 3-pole frame that fits standard switchboard and panelboard mounting patterns without special adapters. Front face carries an IP40 protection rating, suitable for general indoor panel environments where tools or fingers won't contact live parts. Maximum power dissipation is 80 W at rated load, so panel thermal calculations should account for that heat — particularly in sealed or compact enclosures.","metaTitle":"Siemens 3VM1332-4ED32-0AA0 SENTRON MCCB, 320 A, 3-Pole","metaDescription":"Siemens SENTRON 3VM1332-4ED32-0AA0 molded case circuit breaker, 320 A, 3-pole, 121 kA at 240 V.
