The TM210 line protection provides fixed overload protection at Ir = 40 A and a fixed short-circuit pickup at Ii = 10 × In (400 A). That means no field-adjustable dials for the thermal or magnetic settings — what you order is what protects the circuit. The nut keeper kit included (ZD00 suffix) is a detail for the DC Power OEM channel in China; it secures the breaker's busbar connection in high-vibration shipping or panel builds. ## Breaking Capacity — What Class M Means on the Panel Siemens rates the 3VA1 frame in three breaking capacity classes: S (standard), M (medium), and H (high). This unit carries the M class at 55 kA Icu @ 415 V AC. For a 160 A frame, that 55 kA figure sits above the typical 25–36 kA for standard-duty MCCBs, meaning it can clear a bolted fault at the main lug without upstream fuses or a larger frame. If your SCCR study calls for 50 kA at the panel entry, this breaker covers it without stepping up to a 250 A frame. ## Integration Notes — Frame and Mounting The nut keeper kit (ZD00) retains the busbar connection hardware — useful if the breaker ships loose to an OEM line in China where final torque is applied at the panel shop. The TM210 trip unit is fixed, so verify the 40 A Ir matches your load before committing the BOM; there is no field adjustment range to cover a 50 A conductor.","metaTitle":"3VA1140-5ED32-0AA0-ZD00 Siemens 3VA1 40A Circuit Breaker, 55","metaDescription":"Siemens 3VA1140-5ED32-0AA0-ZD00 IEC frame 160, 40A TM210 overload, 55kA @ 415V breaking capacity.
