That's a practical advantage for a panel in a hot machine room or near a furnace line — you don't have to oversize the frame for ambient temperature.","metaTitle":"Siemens 3VA2140-7JP46-0AA0 SENTRON MCCB, 40 A, 4-Pole, 330 k","metaDescription":"Siemens SENTRON 3VA2140-7JP46-0AA0 molded case circuit breaker. 40 A continuous, 4 poles, ETU550 release.
