Its breaking capacity ranges from 75.6 kA at 240 V down to 7.5 kA at 690 V, so the same frame covers high-fault panels at lower voltages and still interrupts a 7.5 kA fault on a 690 V line — useful when a single MCCB type must be specified across a mixed-voltage plant. The TM210 overcurrent release is a thermal-magnetic trip unit — the thermal element handles overloads with an inverse-time curve, the magnetic element snaps on short-circuit.
Temperature derating — the real current you get
Above that, the continuous current must be reduced: 30.72 A at 55 °C, 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C. The storage limit is wider because the breaker isn't carrying current — that's the handling limit, not the running limit.
Front protection is IP40 — splash-resistant from the front, but the terminals and sides are not sealed. Mount it inside a panel with at least IP54 enclosure if washdown or dust is present.
Auxiliary release and accessories
The specific accessory order code for the integrated shunt trip is 3VA9688-0BL30. No undervoltage release, no auxiliary contacts, no communication module are fitted on this variant. If you need remote status feedback or undervoltage protection, you'd order a different 3VA configuration or add external aux contacts separately.
