The integrated auxiliary trip order code is 3VA9688-0BL33. There is no undervoltage release, no auxiliary contact version, no communication function, no phase failure detection, and no ground fault monitoring. The trip indicator is also absent. For applications requiring remote tripping via a control signal, the shunt trip is present; everything else must be added externally.","metaTitle":"Siemens 3VA1020-3ED32-0KA0 SENTRON MCCB, 20 A, 75.6 kA at 24","metaDescription":"Siemens 3VA1020-3ED32-0KA0 SENTRON molded case circuit breaker, 3-pole, 20 A rated continuous current, TM210 release, 75.6 kA breaking at 240 V.
