That matters for panels that run warm; you don't lose headroom the moment the ambient ticks up. The overcurrent release is a TM210 thermal-magnetic type — fixed thermal pickup, adjustable magnetic trip. The auxiliary release is a shunt trip (STL), so you can remotely trip the breaker via a separate control signal, which is handy for emergency-stop circuits or remote disconnect scenarios. ## Breaking capacity — what it handles on a fault This MCCB's interrupting rating depends on the system voltage: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. That's a lot of fault-clearing muscle at the lower voltages — enough for high-available-fault-current panels downstream of a large transformer. The breaker dissipates 17.3 W at full load — something to account for in a dense panel's thermal budget. The breaker measures 130 mm high, 101.6 mm wide, and 70 mm deep — a 4-pole frame that fits standard Siemens 3VA mounting accessories and busbar systems.","metaTitle":"Siemens 3VA1063-4ED42-0HA0 SENTRON MCCB, 63 A, 4-Pole, 121 k","metaDescription":"Siemens 3VA1063-4ED42-0HA0 SENTRON molded case circuit breaker, 63 A, 4-pole, TM210 release, shunt trip.
