The adjustable thermal-magnetic trip can be set between 300 A and 1500 A, giving you a wide band to coordinate with the motor's locked-rotor current and the upstream feeder.
Breaking capacity — the real-world so-what
The interrupting ratings are what separate this MCCB from a standard feeder breaker. At 240 V it clears 330 kA; at 415 V and 440 V it holds 242 kA; at 500 V it drops to 187 kA. The 690 V figure of 3.7 kA tells you this is not the breaker for a 690 V motor branch unless the available fault current is very low.
Built-in undervoltage release
The trip indicator is not fitted, so you won't get a local mechanical flag showing whether the breaker tripped on overload, short, or UVR; plan for a remote indication if the application requires it.
That matches the SENTRON 3VA series being the current-generation MCCB platform.
It mounts directly to a back panel or DIN rail via integral mounting lugs. The depth of 86 mm (3.39 in) fits in most enclosures with room for wiring behind it.
Maximum power dissipation is 12.5 W at rated current. In a sealed enclosure with multiple breakers side by side, that heat adds up — allow for natural convection or a ventilation grille if the ambient inside the panel approaches the 70 °C operating maximum.
