That curve matters if this breaker sits in a non-air-conditioned enclosure near a heat source; the continuous rating drops roughly 1.5 A per 5 °C step above 50 °C, so a panel designer sizing for a 60 A load at 60 °C needs the 59.22 A derated figure, not the 63 A nameplate. Breaking capacity is voltage-dependent: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. The 690 V rating (7.5 kA) covers 600 V class drives and mining gear, though the capacity drops significantly at that voltage. ## Built-in trip options and panel fit The overcurrent release is a TM210 thermal-magnetic type — no electronics, no communication function, no phase-failure detection. That makes it a straightforward fit for standard feeder protection where you want the simplicity of a bimetal and solenoid trip without a power supply to the trip unit. A shunt trip (STL) is integrated as the auxiliary release, so remote tripping via a control signal is wired directly; the external trip accessory is order code 3VA9688-0BL32. No auxiliary contacts ship with the breaker — if you need a status feedback signal for a PLC or a panel lamp, you add them separately. Dimensions are 70 mm deep, 101.6 mm wide, and 130 mm high — a standard 4-pole MCCB footprint that drops into most SENTRON panelboards and DIN-rail adapters without a panel rework. ## Environmental range and endurance The 70 °C upper operating limit matches the derating curve above 50 °C — the breaker runs, but at a reduced continuous current.","metaTitle":"Siemens 3VA1063-2ED42-0JA0 SENTRON MCCB, 63 A, 4-Pole, 52.5","metaDescription":"Siemens 3VA1063-2ED42-0JA0 SENTRON molded case circuit breaker. 63 A rated, 4-pole, 52.5 kA at 240 V.

No panel rework or bus-bar relocation is needed for the swap — the footprint is the same.
