160 A MCCB with high interrupting capacity for line protection
Its interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V — figures that cover high-fault scenarios downstream of large transformers or in utility-tied services. The trip indicator is absent, so remote trip indication depends on the auxiliary switch state.
Current derating and interrupting performance across voltage
The 160 A rating holds flat from 40 °C to 50 °C (–), then derates to 156 A at 55 °C, 151 A at 60 °C, 147 A at 65 °C, and 142 A at 70 °C (–). This thermal curve means the breaker delivers full rated current in most ventilated enclosures; only at sustained ambient above 50 °C does the ampacity drop. Interrupting capacity degrades with system voltage: 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 (–).
Active production, sourcing via RFQ
This order code carries a lifecycle stage of "current", meaning Siemens continues to manufacture the 3VA1216-5EF32-0DC0 as an active catalog item. No last-time-buy or phase-out notice applies. For volume BOM commitments, request a firm quotation with lead time.
The undervoltage release coil and auxiliary switches are factory-integrated; no field-assembly of accessories is required for this variant.
