The four-pole design handles three-phase-plus-neutral or three-phase with switched neutral applications. Breaking capacity is the headline figure for this frame: 121 kA at 240 V, 76 kA at 415 V, and 53 kA at 440 V.
The 3VA platform is Siemens' current-generation MCCB family, so documentation, accessories, and coordination data are all actively supported. No last-time-buy window to track.
The 3VA1110-4FE46-0AA0 measures 101.6 mm wide, 130 mm tall, and 70 mm deep — a 4-inch-wide footprint that matches the standard SENTRON 3VA frame. It mounts via screw terminals onto a mounting plate or DIN rail adapter (not integral DIN-rail clip; the 3VA frame uses a separate mounting bracket for DIN or panel-mount). The N-conductor protection is set at 50% of the phase rating — a common setting for distribution where the neutral is not expected to carry full phase current.
Selectivity and coordination context
The TM220 release provides fixed thermal (overload) and fixed magnetic (short-circuit) trip characteristics — no interchangeable trip units.
