Breaking capacity reaches 330 kA at 240 V and 242 kA at 415 V, tapering to 3 kA at 690 V; those numbers tell you this breaker is built for high-fault locations like transformer secondaries or large motor control centers where fault current can exceed 200 kA. The adjustable thermal-magnetic trip range spans 150 A to 1 200 A (the maximum setting), so the 100 A frame can be tuned to protect feeders well above its continuous rating — typical for an MCCB with an electronic trip unit. Ground-fault monitoring is built in as summation current sensing on L+N conductors, which covers TN and TT systems without an external module.
The 140 mm width is standard for a 4-pole MCCB in the SENTRON 3VA platform, so it drops into the same mounting footprint as other 4-pole 3VA frames.
