32 A MCCB with TM210 release — line protection for distribution panels
Its TM210 thermal-magnetic release handles overload and short-circuit curves without external trip units — a fixed-trip design that simplifies BOM management on panel builds where the customer's approved vendor list (AVL) specifies SENTRON for the distribution section. Rated 32 A at 40 °C through 50 °C without derating; above 50 °C the current tapers to 28.8 A at 70 °C. That thermal profile means the breaker holds its full rating across most panel ambient conditions — only above 55 °C does the integrator need to check the derate curve against the actual enclosure temperature. Breaking capacity is 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. For a 415 V distribution board this gives 32 kA SCCR — enough to coordinate with most downstream panelboard breakers without requiring a current-limiting upstream device.
Integrated undervoltage release and auxiliary contacts
That is a common requirement for safety circuits and emergency-stop chains where the MCCB must open when the control supply drops. The alarm switch changes state only on a fault trip, not on manual switching — useful for remote annunciation in a PLC input or a panel lamp circuit. The 3-pole footprint measures 76.2 mm wide by 130 mm tall by 70 mm deep, matching the standard SENTRON 3VA mounting grid for busbar or cable connection.
Current lifecycle — active production, no phase-out notice
The integrated auxiliary trip accessory is order code 3VA9608-0BB24 — if the panel BOM already carries that accessory, verify it matches this breaker's release interface.
