It carries a continuous current rating of 100 A at 40 °C, holds that rating through 50 °C, and derates to 91 A at 70 °C — so for most panel environments below 50 °C it delivers full rated current without headroom loss. The 3-pole construction and 800 V rated insulation voltage suit it for 400/480 VAC three-phase systems common in industrial and commercial switchboards.
The interrupting ratings span the voltage range a panel sees in practice: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500/690 V.
Release and auxiliary options
The auxiliary release is a shunt trip (STL), which lets a remote signal (e.g., emergency stop, fire alarm, undervoltage relay) open the breaker. There is no undervoltage release on this variant, so if you need UVR for motor starter coordination, look at the -0LA0 sibling. The unit has no trip indicator, no communication function, and no ground-fault monitoring — it is a straight line-protection breaker for standard distribution.
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that fits most Siemens SENTRON panelboards and third-party enclosures with DIN-rail or bolt-on mounting.
