What this MCCB delivers
Its TM210 thermal-magnetic release combines a thermal bimetal for overloads and a magnetic coil for short-circuits, no electronic adjustment. Rated 100 A continuous at 40 °C (derated to 91 A at 70 °C), it handles a 4-pole configuration for three-phase-plus-neutral or three-phase switched-neutral applications. Interrupting capacity is the headline: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 500/690 V. That 52.5 kA figure is the high-fault rating for 240 V systems (common in North American panelboards), while the 32 kA at 415 V covers European 400 V distribution. Dimensions are 70 mm deep, 101.6 mm wide, 130 mm high — a compact 4-pole footprint that fits standard DIN-rail or panel-mount enclosures.
Auxiliary switch complement and trip signalling
The auxiliary switches follow the main contacts (open/closed), while the trip alarm switch only changes state when the breaker trips on a fault — useful for remote fault indication without wiring through the main contacts. The basic switch core is order code 3VA10102ED420AA0 — that's the internal switching mechanism. If you ever need to replace just the switch block (not the whole breaker), that's the part number to order. Trip indicator present as standard, so you get a visible red flag when the breaker has tripped.
