The breaker ships with a shunt trip (STL) rated 220–250 V DC / 208–277 V AC, two auxiliary switches (HQ), and one trip alarm switch (HQ). Below that, the TM210 thermal element provides overload protection with a fixed Ir of 80 A, so the breaker is sized for a continuous load up to 80 A. The instantaneous pickup at 10 × In (800 A) clears hard faults fast, which helps with cable protection in IEC 60947-2 applications. The shunt trip allows remote tripping from a safety relay or E-stop circuit; it operates on either 220–250 V DC or 208–277 V AC, so it can be wired into a control transformer secondary or a DC UPS bus without an extra converter.","metaTitle":"Siemens 3VA1080-4ED32-0KH0 Circuit Breaker, 80A, 36kA @ 415V","metaDescription":"Siemens 3VA1080-4ED32-0KH0 circuit breaker, IEC frame 100, 3-pole, 80A fixed TM210, 36kA Icu @ 415V, shunt trip, aux switches.
