The Siemens 3VA1063-3ED42-0DH0 is a 4-pole IEC frame 100 molded-case circuit breaker rated 63 A continuous (Ir fixed at 63 A) with a TM210 thermal-magnetic trip unit — the thermal element handles overloads, the magnetic element (fixed at 10 x In, so 630 A) clears short-circuits.
Deployment context — panel integration
The nut keeper kit (included) secures the breaker to the mounting plate without loose hardware — a time-saver during panel assembly. The UVR coil draws power from the control circuit (208–230 V AC); verify the control transformer is sized to handle the inrush. Auxiliary and alarm switches are pre-wired to terminal blocks on the breaker face, simplifying the wiring to the PLC input card.
