The TM210 thermal-magnetic release gives fixed thermal and magnetic trip thresholds, no electronic adjustment. Breaking capacity hits 187 kA at 240 V AC and 121 kA at 415/440 V AC, which means it can interrupt fault currents up to those levels without upstream cascading — important for high-fault installations like industrial mains or transformer secondaries. ## Sourcing and lifecycle — still current, quoted to order No official successor exists because none is needed. ## Panel integration — footprint and mounting Front IP40 protection means it's suited for enclosed panel mounting where no water jets or dust ingress are expected.","metaTitle":"Siemens 3VM1340-5ED32-0AA0 SENTRON MCCB, 400 A, 3-Pole, TM21","metaDescription":"Siemens SENTRON 3VM1340-5ED32-0AA0 molded case circuit breaker, 400 A rated at 40 °C, 3-pole, TM210 release, 187 kA at 240 V.
