Rated insulation voltage is 800 V, and the breaking capacity varies sharply with system voltage: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V.
Current rating holds across temperature — no derate needed up to 70 °C
That is unusual for an MCCB; most require a reduction above 40 °C.
This part carries a current-production lifecycle status — it is still in the SENTRON catalog as an active line. No last-time-buy window, no successor part to cross-reference.
The 140 mm width on a 4-pole MCCB is standard for the SENTRON 3VA2 frame — it occupies the same footprint as other 4-pole units in the series, so a panel layout designed for a 3VA2 4-pole breaker accepts this one without re-spacing the DIN rail or drilling new gland-plate holes. Suitable for indoor panel mounting where the breaker is behind a closed cabinet door. No IP rating on the sides or rear; clearance to grounded metal per the manufacturer's mounting instructions applies.
