The interrupting ratings climb to 242 kA at 240 V and stay at 187 kA through 440 V, then drop to 121 kA at 500 V and 3.8 kA at 690 V — so on a 480 V delta service you've got serious fault-current headroom. The 3VA2140-6KQ36-0AA0 measures 105 mm wide, 181 mm tall, and 86 mm deep — that's about 4.1 by 7.1 by 3.4 inches. The ETU860 trip unit is adjustable on the front face, so you can set the long-time and short-time delays and the ground-fault parameters without pulling the breaker out of the panel.","metaTitle":"Siemens 3VA2140-6KQ36-0AA0 SENTRON MCCB, 40 A, 3-Pole, 242 k","metaDescription":"Siemens 3VA2140-6KQ36-0AA0 SENTRON MCCB, 40 A rated continuous current, 3-pole, line protection, 242 kA at 240 V.
