Above that it derates linearly: 19.2 A at 55 °C, 18.8 A at 60 °C, 18.4 A at 65 °C, and 18 A at 70 °C. The case dimensions are 130 mm high by 76.2 mm wide by 70 mm deep, and it carries an IP40 front protection rating, so it's fine for general indoor panel mounting but not for washdown areas. No auxiliary contacts, no communication module, no undervoltage release — this is a bare-bones line-protection breaker with a shunt trip for remote opening.","metaTitle":"Siemens 3VA1120-6EF36-0JA0 SENTRON MCCB, 20 A, 3-Pole, 220 k","metaDescription":"Siemens SENTRON 3VA1120-6EF36-0JA0 molded case circuit breaker, 20 A rated, 3-pole, 220 kA interrupting at 240 V.
