The TM220 trip unit provides adjustable overload protection (Ir = 70…100 A) and a fixed short-circuit pickup at Ii = 10 x In. The thermal element tracks cable heating; the magnetic element clears hard shorts instantly. This variant ships with the N conductor unprotected (no integral neutral protection) and includes a nut keeper kit. It is configured for a DC Power OEM in China — the nut keeper kit simplifies bus-bar assembly in OEM switchgear builds where the breaker lands on a pre-drilled copper grid. ## Integration into a panel or OEM assembly The nut keeper kit supplied with this variant holds M6 or M8 bus-bar nuts captive during assembly — a time-saver on repetitive OEM builds where the breaker lands on a pre-drilled bus-bar grid. Four-pole configuration occupies the full width of a 4-module DIN cutout. Plan for side clearance per Siemens mounting instructions to allow arc-chamber gas venting.","metaTitle":"Siemens 3VA1110-5EE42-0AA0-ZD00 Circuit Breaker, 100A, 55kA","metaDescription":"Siemens 3VA1110-5EE42-0AA0-ZD00 IEC frame 160 MCCB, 4-pole, 100A, 55kA breaking capacity at 415V.
