SENTRON 3VA1216-5EF32-0JA0 — 160 A MCCB with TM240 Release
Its interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V — figures that govern selectivity coordination in high-fault panels. The TM240 release means the thermal element tracks load heating; the magnetic pickup is fixed at the TM240 curve, so no field adjustment of the short-circuit trip threshold is possible. At 70 °C ambient the breaker still carries 142 A, so the 160 A frame holds up in warm enclosures without an immediate upsizing step.
Current Derating and Ambient Temperature
Above that, the current must be derated: 156 A at 55 °C, 151 A at 60 °C, 147 A at 65 °C, and 142 A at 70 °C. If your panel ambient sits at 60 °C and the load is 155 A, this frame still fits. Maximum power loss is 33 W — account for that in the enclosure thermal budget.
The 3-pole footprint matches the standard SENTRON 3VA frame pattern — if your panel was laid out for a 3VA1010-2ED32-0JA0, the 160 A unit occupies the same 105 mm width but requires checking the busbar and lug clearances for the higher current path. No auxiliary contacts or undervoltage release are included on this order code; those are added via separate accessory modules.
