What the ratings mean for the panel
The Siemens 3VA1180-6ED42-0AA0-ZD00 is a 4-pole IEC frame 160 circuit breaker with breaking capacity class H — Icu of 70 kA at 415 V. The TM210 trip unit has Ir fixed at 80 A and Ii fixed at 10 x In.
Deployment and integration
This breaker mounts on a DIN rail. The 4-pole configuration with an unprotected N conductor means the neutral is not switched.
Lifecycle and sourcing posture
The lifecycle stage is listed as current, meaning Siemens still manufactures this order code. It is not subject to a last-time-buy or phase-out notice. For BOM-line commitment, the key fit criteria are the 80 A fixed Ir, the 70 kA interrupting rating at 415 V, and the 4-pole form factor with unprotected neutral. This part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
