At 415 V the breaking capacity holds at 121 kA, dropping to 79 kA at 500 V and 3.4 kA at 690 V; that 690 V figure is the practical ceiling for this frame size in IEC applications.
Dimensions are 181 mm high, 105 mm wide, 86 mm deep, which fits standard SENTRON 3VA mounting footprints; verify busbar and lug clearance against the existing panel layout, especially the 86 mm depth behind the mounting plane.
This MCCB is sourced and quoted to order against an RFQ through independent distribution. Current pricing and availability are confirmed at quote time — no stock count or price figure is published here.
At 240 V the interrupting rating is 187 kA; at 415 V and 440 V it is 121 kA; at 500 V it drops to 79 kA; and at 690 V the rating is 3.4 kA. These figures govern where the breaker can be applied in high-fault panels.
The factory-fitted auxiliary contact block includes two auxiliary switches, one trip-alarm switch, and one electrical-alarm switch — four discrete signals for status monitoring.
Yes, it is equipped with a shunt trip (STL) release for remote tripping via a control voltage. No undervoltage release is fitted.
