This simplifies panel sizing in warm enclosures or near other heat sources. The 800 V rated insulation voltage (Ui) and 690 V AC / 500 V DC operational voltage (Ue) cover standard 400/480 V and 690 V industrial distribution. The part is a pure disconnect — no overload or short-circuit protection elements inside. It is designed for applications where isolation and remote trip capability are needed, but protection is handled upstream or by a separate device. Mechanical service life is 15,000 operating cycles typical. The main circuit connects via busbar connection with front terminals — no lug terminal option on this variant.
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — the same footprint as the 3VA1 IEC frame 160 molded-case circuit breakers. The front terminal arrangement and busbar connection pattern match the 3VA breaker family, so it can share busbar systems and panel cutouts with the line-protection variants. Maximum power loss is 38 W at rated current — account for this in enclosure thermal calculations, especially in multi-unit panels.
