It is rated 30 A at 40 °C, with interrupting capacity of 65 kA at 240 V AC and 25 kA at 480 V AC — figures that govern its use as a main or feeder breaker in distribution panels where fault current levels are known.
At 240 V the breaker clears 65 kA; at 480 V that drops to 25 kA, and at 600Y/347 V it is 14 kA.
Current rating is temperature-dependent: 30 A at 40 °C, derating to 29 A at 45–50 °C, 28 A at 55 °C, 27 A at 60–65 °C, and 26 A at 70 °C.
Dimensions are 76.2 mm wide, 129.4 mm high, and 75.1 mm deep — a standard 3-pole MCCB footprint that fits most Siemens SENTRON panelboards and distribution blocks. The breaker is rated for 690 V AC and carries UL file SEAB, confirming UL 489 listing for the US market.
