SENTRON 3VA1063-4ED32-0AH0 — 63 A MCCB, Line Protection, TM210 Release
The TM210 overcurrent release is a fixed thermal-magnetic unit — thermal for overload protection, magnetic for short-circuit.
At 240 V this breaker interrupts 121 kA — that's the full rated short-circuit current without upstream fusing in most 240 V distribution schemes. At 415 V it still handles 75.6 kA, dropping to 52.5 kA at 440 V and 11.9 kA at 500 V and 690 V. For a 63 A frame, those numbers give real selectivity headroom against a downstream 10–25 A branch breaker: the high interrupting capacity lets you coordinate without oversizing the main. The 3-pole construction fits three-phase line protection — common in industrial distribution panels feeding motor control centers or lighting subpanels.
Panel Fit and Auxiliary Switching
The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a compact 3-pole footprint that mounts on a DIN rail or panel-mount adapter in standard distribution enclosures. The auxiliary switches are pre-configured; no field wiring of add-on modules is needed for basic open/closed and trip indication.
Environmental and Storage Range
Maximum power loss is 17.3 W — relevant for thermal budgeting in sealed enclosures. The trip indicator is standard, so a visual check confirms the breaker tripped on fault versus being manually opened.
