That rating places it in the medium-high fault-current tier for IEC distribution panels, sized for industrial main or sub-feed protection where the prospective short-circuit current sits above 25 kA but below 65 kA. The TM210 trip unit provides fixed thermal-magnetic line protection: In = 100 A, Ir = 100 A (overload), and Ii = 10 × In (short-circuit magnetic pickup at 1000 A). N-conductor protection is set at 100%, meaning the neutral pole tracks the phase poles — typical for 4-wire systems where the neutral carries full phase current. For IEC 60947-2 installations, this class M rating covers most industrial distribution boards fed from a transformer in the 1–2 MVA range. If your available fault current exceeds 55 kA, you need a higher-class frame (class H or class L in the 3VA family). The fixed Ir = 100 A and Ii = 10 × In (1000 A) means this is not field-adjustable for load changes. If the downstream load is exactly 100 A and the cable is sized for that, it fits. If you need a different overload setting or a wider magnetic pickup range, you would look at the 3VA2 series with electronic trip units. ## Deployment Context This 4-pole MCCB mounts in a standard IEC distribution panel or switchboard via the 3VA mounting accessories. The nut keeper kit simplifies panel-builder installation for the DC Power OEM application it was configured for. No DIN-rail mounting — this is a bolted-frame breaker for fixed or withdrawable chassis.","metaTitle":"Siemens 3VA1110-5GD42-0AA0-ZD00 Circuit Breaker, 100A, 55kA","metaDescription":"Siemens 3VA1110-5GD42-0AA0-ZD00 IEC frame 160 MCCB, 4-pole, 100A TM210, 55kA Icu @ 415V.
