The interrupting ratings are 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V, which gives you the SCCR headroom for high-fault utility feeds or transformer secondaries. The thermal derating curve is flat from 40 °C to 50 °C at 20 A, then drops to 19.2 A at 55 °C, 18.8 A at 60 °C, 18.4 A at 65 °C, and 18 A at 70 °C. For a panel that runs warm near the top of a switchboard, you can still count on 18 A at 70 °C — no need to oversize a frame for ambient. ## Auxiliary and Trip Configuration The shunt trip allows remote tripping from a PLC or emergency-stop circuit — useful when the MCCB is in a remote panel and you need a hard-wired trip without a communication module. The integrated auxiliary trip order code is 3VA9688-0BL30, which is the factory-fitted accessory. There is no undervoltage release, no ground fault monitoring, no phase failure detection, and no communication function — this is a pure line-protection breaker with a remote trip capability. ## Mechanical Endurance and Environmental Range The latching endurance is rated at 15,000 operations — typical for a distribution MCCB that sees infrequent switching. Front protection is IP40, which means it is protected against tools and small wires entering from the front, but not against dust ingress from the sides — standard for panel-mounted breakers. Dimensions are 130 mm height, 76.2 mm width, and 70 mm depth, fitting the standard 3-pole SENTRON 3VA footprint.","metaTitle":"Siemens 3VA1020-3ED36-0HH0 SENTRON MCCB, 20 A, 3-Pole, 75.6","metaDescription":"Siemens 3VA1020-3ED36-0HH0 SENTRON molded case circuit breaker, 20 A rated continuous current, 3-pole, line protection, TM210 release, 75.6 kA at 240 V.

Both are 3-pole, 20 A, TM210 line-protection MCCBs with the same interrupting ratings and dimensions. The -0HH0 variant adds the shunt trip (STL) and the 2 aux + 1 trip alarm switch configuration; the -0AA0 is the base variant without those accessories. If your panel was specified around the -0AA0 and you need the shunt trip, the -0HH0 will drop into the same footprint and bus connections without rewiring — just verify the auxiliary wiring plan."},{"question":"Will 3VA1020-3ED36-0HH0 drop into a panel that was specified around 3VA1020-3ED36-0AA0 without rewiring?","answer":"Yes. Both variants share the same 130 mm height, 76.2 mm width, and 70 mm depth, and the same 3-pole bus-bar connection pattern. The -0HH0 adds the shunt trip and auxiliary switches, so you gain remote trip capability without changing the mounting or power connections."},{"question":"What compliance documentation does this brand provide for 3VA1020-3ED36-0HH0?","answer":"Siemens SENTRON MCCBs carry CE marking for the European market and are designed to meet IEC 60947-2.
