The TM220 overcurrent release combines a thermal fixed-trip element for overloads with a magnetic short-circuit trip, no electronic adjustments to fail or mis-set. Breaking capacity is 121 kA at 415 V and 440 V, dropping to 75.6 kA at 500 V and 11.9 kA at 690 V. At 240 V it reaches 187 kA. If your spec calls for shunt trip or aux contacts, you need the -5EE32-0AA0 suffix variant with those options.","metaTitle":"Siemens 3VA1332-5EE32-0AA0 SENTRON MCCB, 320 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA1332-5EE32-0AA0 molded case circuit breaker, 320 A rated, 3-pole, TM220 release, 121 kA at 415 V.
