Its interrupting capacity hits 187 kA at 240 V, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 3.7 kA at 690 V. ## Integration and panel fit The front face carries an IP40 protection class, suitable for dry indoor panels where tools or fingers might contact the front but not the terminals. ## Key features for line protection Equipped with an ETU560 electronic trip unit, configurable for line protection. Includes a ground-fault monitoring function using summation current formation on the L-conductor. Communication function is built in, and a motor drive option is available for remote operation. Maximum power loss is 1.6 W.","metaTitle":"Siemens 3VA2140-5JQ32-0AA0 SENTRON MCCB, 40 A, 187 kA at 240","metaDescription":"Siemens 3VA2140-5JQ32-0AA0 SENTRON molded case circuit breaker, 40 A continuous, 187 kA interrupting at 240 V.
