It carries LSoI protection functions — long-time overload (L), short-time short-circuit with fixed delay (So), and instantaneous short-circuit (I) — all adjustable within the trip unit's settings. The 3-pole design (3D protected poles) handles 690 V AC at 50/60 Hz, making it a direct fit for generator feeders in switchboards and distribution panels. If your generator feeder sees ambient above 40 °C, you'll need to apply the manufacturer's derating curve — the trip unit's electronic thermal memory holds a 20-minute pre- and post-trip profile, so it remembers load history even after a brief outage. The long-time pickup (Ir) adjusts from 100 A to 250 A in nine steps, letting you match the generator's full-load amp rating exactly. Short-time pickup (Isd) is adjustable from 1.5 to 9 times Ir, which gives selectivity headroom downstream — critical when coordinating with feeder breakers on a generator bus. Instantaneous pickup (Ii) is fixed at 3000 A, meaning it clears hard faults fast but won't nuisance-trip on motor inrush below that threshold. ## Where it goes — generator protection in switchgear This trip unit is designed for generator application, which means its protection curves are shaped for the thermal and fault characteristics of a generator feeder — not a standard distribution feeder. You'll find it in low-voltage switchboards feeding backup generators, cogeneration tie-ins, or prime-power gensets. The EN/IEC 60947-2 standard certifies it for circuit-breaker duty in industrial installations, with pollution degree 3 handling the conductive dust and humidity you'd expect in a generator room or outdoor container. IP40 front-face protection keeps fingers and tools out, but the breaker itself needs panel-side sealing if it's in a washdown area.","metaTitle":"C2532G250 MicroLogic 2.2 G Trip Unit, 250 A, Generator Prote","metaDescription":"C2532G250 MicroLogic 2.2 G trip unit for ComPacT NSX250. 250 A rating at 40 °C, LSoI protection, generator application, EN/IEC 60947-2.

The standard 2.2 unit shares the same LSoI protection functions and 250 A frame but uses curves optimized for distribution feeders rather than generator protection. If your application is a generator feeder, stick with the 2.2 G — the curve shaping matters for coordination with generator damage curves."},{"question":"What standards does C2532G250 comply with?","answer":"The C2532G250 complies with EN/IEC 60947-2, the standard for low-voltage switchgear and controlgear circuit-breakers.
