The interrupting ratings are 121 kA at 240 V AC (cite:), 76 kA at 415 V and 440 V AC (cites:,), and 53 kA at 500 V AC (cite:); these are the SCCR values for selectivity studies. The 800 V rated insulation voltage (cite:) and 690 V AC / 500 V DC max operating voltages (cites:,) cover standard 480/277 V and 600 V distribution panels. The 3VM1332-4EE42-0AA0 measures 110 mm deep, 184 mm wide, and 248 mm high (cites:,). The 80 W maximum power loss (cite:) should be factored into the panel thermal budget; a 4-pole MCCB at full load dissipates that heat into the enclosure.","metaTitle":"SENTRON 3VM1332-4EE42-0AA0 MCCB, 320 A, 4-Pole, 121 kA at 24","metaDescription":"SENTRON 3VM1332-4EE42-0AA0 molded case circuit breaker, 320 A, 4-pole, TM220 release, 121 kA at 240 V.
