No auxiliary contacts or communication module are fitted on this variant, so any status feedback to a PLC must come from an external auxiliary switch block or the separate 3VA9608-0BB25 auxiliary trip unit. In a sealed, uncooled enclosure the effective current may be lower — factor the derating curve into the panel thermal budget. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep, which fits the standard SENTRON 3VA mounting footprint. Front IP40 protection means the breaker is suited for dry indoor panels; no washdown rating. The undervoltage release coil draws its supply from the control circuit — verify the coil voltage matches the panel's control transformer output before wiring.","metaTitle":"Siemens 3VA1120-6EF36-0DA0 SENTRON MCCB, 20 A, 220 kA at 240","metaDescription":"Siemens SENTRON 3VA1120-6EF36-0DA0 molded case circuit breaker, 3-pole, 20 A rated, 220 kA at 240 V.
