The TM240 overcurrent release handles the thermal-magnetic trip curve, so it responds to sustained overloads and short-circuit events without an external relay. Breaking capacity is the headline number for an MCCB: this one delivers 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. It does not carry undervoltage release, auxiliary contacts, ground-fault monitoring, phase-failure detection, or communication functions. The integrated auxiliary trip is order code 3VA9688-0BL33 if you need to add remote indication later. Front protection is IP40, meaning it's splash-resistant from the front but not sealed for washdown environments. The 63 A continuous rating with flat thermal performance up to 50 °C means this breaker won't nuisance-trip on a warm panel floor. At 480 V (415 V class), the 75.6 kA rating still covers most industrial service-entrance faults. If you need adjustable long-time or short-time pickup, look at the electronic-trip variants in the 3VA family.","metaTitle":"Siemens 3VA1163-4EF36-0KA0 SENTRON MCCB, 63 A, 121 kA at 240","metaDescription":"Siemens SENTRON 3VA1163-4EF36-0KA0 molded case circuit breaker, 3-pole, 63 A rated, 121 kA breaking capacity at 240 V.
