Footprint is 105 mm wide × 181 mm tall × 86 mm deep — standard 3-pole MCCB envelope for a 40 A frame. Bolts onto the mounting plate; line and load lugs accept copper or aluminum conductors sized for the 40 A rating. Interrupting ratings: 242 kA at 240 VAC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V. ## Ground-fault and monitoring This variant includes summation-current ground-fault monitoring on the L conductors — it measures vector sum of the phase currents to detect leakage to ground. No separate voltage trigger or communication function on this order code.","metaTitle":"Siemens 3VA2040-6HM36-0AA0 SENTRON MCCB, 40 A, 3-Pole, 242 k","metaDescription":"Siemens 3VA2040-6HM36-0AA0 SENTRON molded case circuit breaker, 40 A rated, 3-pole, 242 kA breaking capacity at 240 VAC.
