Its interrupting capacity reaches 121 kA at 240 V and 75.6 kA at 415 V, making it suitable for high-fault-current panelboards and distribution boards where a standard MCB would not hold. Above 50 °C it drops to 30.72 A at 55 °C and 28.8 A at 70 °C, which matters if this breaker sits near heat sources or in a non-ventilated enclosure. The 121 kA at 240 V figure governs its use on the secondary side of a 208Y/120 V transformer or a 240 V delta service; at 480 V the available fault current must be below 75.6 kA, and at 600 V class (690 V rated) the limit is 11.9 kA. The TM210 release is fixed thermal and magnetic — no field-adjustable trip settings, so the breaker is selected for a specific load current, not tuned on site. ## Panel integration and mechanical fit At 76.2 mm wide, 130 mm tall, and 70 mm deep, this MCCB occupies a standard 3-pole footprint for the SENTRON 3VA platform. The 15 000-cycle latching endurance (mechanical) suits applications with occasional switching, not daily load-break duty.","metaTitle":"Siemens 3VA1032-4ED32-0AD0 SENTRON MCCB, 32 A, 3-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1032-4ED32-0AD0 molded case circuit breaker, 32 A rated continuous current, 3-pole, TM210 release, 121 kA at 240 V.
