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.","metaTitle":"Siemens 3VA1216-5EF32-0DC0 SENTRON MCCB, 160 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA1216-5EF32-0DC0 molded case circuit breaker, 160 A at 40 °C, 3-pole, 187 kA interrupting at 240 V.
