The 80 A rating holds steady from 40 °C up to 50 °C, then derates to 72 A at 70 °C, so the ambient temperature inside the enclosure drives the actual ampacity you can count on. The 121 kA at 240 V and 75.6 kA at 415 V are the short-circuit current ratings (SCCR) — the maximum fault current this breaker can safely interrupt at those voltages. For a 480 V panel fed from a 1000 kVA transformer, the available fault current often exceeds 50 kA; this MCCB handles that with headroom. The IP40 protection on the front means the breaker face is protected against tools and small wires entering, but the enclosure itself must provide any washdown or dust rating. The TM210 release is a thermal-magnetic trip unit — the thermal element protects against sustained overloads (heating), the magnetic element handles short-circuit instantaneously. It is non-electronic, so no field programming or communication; it is a fixed-characteristic breaker for straightforward line protection where you do not need adjustable long-time or short-time pickup. The trip alarm is normally open and closes only when the breaker trips on fault, so a PLC can distinguish a manual open from a protective trip without extra logic. Its 76.2 mm width (3-pole, standard 25.4 mm per pole) matches the footprint of other SENTRON 3VA frame breakers, so a panel laid out for a 3VA1010 will accept this unit without re-drilling.","metaTitle":"Siemens 3VA1080-4ED32-0HH0 SENTRON MCCB, 80 A, 3-Pole","metaDescription":"Siemens 3VA1080-4ED32-0HH0 SENTRON molded case circuit breaker, 80 A rated continuous current, 3-pole, 121 kA at 240 V.
