It carries a TM240 thermal-magnetic overcurrent release, so the trip curve is fixed at the factory — no interchangeable trip units here, which simplifies spares stocking but means you order the exact amp rating you need.
The interrupting rating is 220 kA at 240 V, dropping to 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 500 V and 690 V.
Thermal derating — don't let the panel oven fool you
Above that it derates: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. The maximum power loss is 19.2 W, which matters for thermal rise calculations in a crowded cabinet.
Approvals and documentation
The product is RoHS and REACH compliant; UL and IEC certifications are standard for the SENTRON series. Compliance documentation (declaration of conformity, CE mark) is available from the manufacturer.
