MCCB for panel protection — 100 A, 3-pole, TM210 release
Breaking capacity reaches 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V — covering most LV fault scenarios without cascading upstream. The 15 000 latching endurance cycles suit frequent-switching applications like motor control centers or capacitor bank switching.
Mounting and integration — 76.2 mm wide, IP40 front
Width at 76.2 mm (3-pole) fits standard MCCB panel cutouts. IP40 on the front face protects against tool entry; the back and sides are unrated, so panel clearance around live busbars is on the installer. No auxiliary contact version fitted as standard. An undervoltage release (UVR) is integrated — design 3VA9608-0BB11 is the trip unit that interfaces with the UVR coil. No communication function, no voltage trigger, no phase failure detection on this variant.
For selectivity studies: the 75.6 kA breaking at 240 V and 52.5 kA at 415 V allow this MCCB to serve as a main or feeder breaker upstream of smaller MCBs. The TM210 release is thermal-magnetic — fixed thermal pickup, fixed magnetic trip at 10× In (typical for TM releases). No electronic adjustment, so coordination is curve-based, not programmable.
