80 A, 4-pole MCCB with TM220 release — active production, high interrupting capacity
The 3VA1180-5EE46-0AA0: Breaking capacity is the headline here: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. Those numbers mean it can safely interrupt very high fault currents at common distribution voltages — useful downstream of large transformers or in high-fault-capacity industrial grids where a standard MCB would weld shut. Current rating holds flat at 80 A from 40 °C through 50 °C, then derates gradually to 74 A at 70 °C. The rated insulation voltage is 800 V, and maximum power loss is 19.2 W. An optional motor drive is available for remote operation.
Lifecycle and sourcing
Lifecycle status is current — this is an active, in-production catalog number from Siemens. No end-of-life notice or last-time-buy window has been published. Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.
Physical fit and panel integration
Dimensions are 101.6 mm wide (4 in), 130 mm tall (5.12 in), and 70 mm deep (2.76 in). That 4-pole width is the main panel-space constraint — it's wider than a 3-pole equivalent. The IP40 front protection means it's suited for enclosed distribution boards where the door provides the environmental seal.
