The TM220 overload unit adjusts Ir from 224 A to 320 A; short-circuit pickup Ii is fixed at 10 x In (3200 A). The ATFM (Adjustable Thermal Fixed Magnetic) trip provides thermal overload and fixed magnetic short-circuit protection. The nut keeper kit simplifies DC Power OEM installations — keeps the bus-bar nuts captive during assembly in Chinese OEM lines.","metaTitle":"Siemens 3VA1332-5GE42-0AA0-ZD00 320A MCCB, 55kA @ 415V, TM22","metaDescription":"Siemens 3VA1332-5GE42-0AA0-ZD00 circuit breaker, 4-pole, 320A, 55kA Icu @ 415V, TM220 overload, ATFM.
