It delivers a 36 kA breaking capacity at 800 V AC, sized for distribution applications where the load profile demands a coordinated LSI curve — long-time overload (L), short-time short-circuit (S), and instantaneous (I) protection in a single electronic package.
Above that, the electronic trip unit's thermal memory (L protection) tracks the heating curve of the conductors, so a series of overloads doesn't let the insulation bake — it accumulates heat and trips earlier on the next event. That's an F performance level in the EasyPact Solar line, which means it's sized for high-fault-current solar distribution panels where the array strings can feed substantial short-circuit energy. The electronic trip unit (ETU) with LSI functions gives you adjustable long-time pickup and delay, short-time pickup and delay, and instantaneous pickup. That's the difference between a thermal-magnetic breaker and this one: you can coordinate selectively with downstream breakers by setting the short-time delay, so a fault on a branch trips the branch breaker first, not the main. The IP20 finger-safe terminals keep personnel out, but the internal creepage distances are designed for degree 3 conditions. Suitability for isolation per EN/IEC 60947-2 means the open contacts provide a visible break that meets the isolation standard — no need for a separate disconnect switch upstream in many configurations, provided local code accepts it.
Fixed mounting on a backplate, 180 mm wide by 250 mm high by 105 mm deep. Horizontal or vertical orientation is permitted, which helps when the enclosure layout forces a non-standard rotation. That heat has to leave the panel — factor it into the ventilation or derating calculation if the ambient around the breaker climbs above 40 °C.
