The TM240 thermal-magnetic trip unit gives an overload adjustment range Ir = 224 A to 320 A, and the instantaneous short-circuit pickup Ii is set between 5 and 10 times In — so you can dial the protection band to match the cable and load without swapping trip blocks. Four-pole construction with 100 % N-conductor protection means the neutral pole is fully rated and trips with the phase poles — essential for TN-S or TN-C-S systems where an open neutral cannot be tolerated. At 55 kA Icu @ 415 V, this breaker coordinates cleanly with downstream 25 kA or 36 kA MCCBs in a selective system — the high interrupting capacity lets it serve as the main or tie breaker without cascading upstream.","metaTitle":"Siemens 3VA1332-5GF42-0AA0-ZD00, 320A 55kA IEC Breaker","metaDescription":"Siemens 3VA1332-5GF42-0AA0-ZD00 circuit breaker, IEC frame 400, 55kA @ 415V, 4-pole, TM240, In=320A, Ir=224-320A, Ii=5-10xIn.
