It is designed for motor protection, with adjustable trip class settings of 10A, 10E, and 20E, letting you match the overload curve to the motor's starting profile. The interrupting capacity reaches 330 kA at 240 V, dropping to 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V — a wide SCCR envelope that supports high-fault installations without cascading upstream. No undervoltage release or shunt trip is built in (the listing shows no voltage trigger and no undervoltage release), so if you need remote trip, plan for an external accessory. Phase failure detection is included, which is useful for motor circuits where a lost phase can cause single-phasing damage. ## Electrical and environmental limits The breaker is designed for motor protection, not as a main disconnect for general distribution.","metaTitle":"3VA2140-7MN36-0AA0 SENTRON MCCB, 40 A, 3-pole, 330 kA at 240","metaDescription":"Siemens SENTRON 3VA2140-7MN36-0AA0 molded case circuit breaker, 40 A, 3-pole, 330 kA interrupting at 240 V.
