The Siemens 3VA1080-3ED32-0AA0-ZD00 is a 3-pole IEC frame 100 circuit breaker in the 3VA1 series, rated with breaking capacity class N and an Icu of 25 kA at 415 VAC. It carries a TM210 thermal-magnetic trip unit with a fixed overload protection setting Ir=80 A and a fixed short-circuit protection threshold Ii=10 x In. The description also notes a nut keeper kit and a DC Power OEM designation for China.
What the ratings mean for fit
The 25 kA Icu at 415 V defines the maximum short-circuit current the breaker can safely interrupt under IEC 60947-2 — critical for verifying the available fault current at the installation point. The TM210 trip unit provides thermal-magnetic protection: the thermal element handles overloads (Ir=80 A fixed), and the magnetic element responds to short-circuits at 10 times the rated current (Ii=800 A). Because Ir is fixed at 80 A and not adjustable, this breaker is specified for a dedicated 80 A load branch, not for applications needing field-adjustable overload protection.
