The 4P configuration with earth-leakage protection (integral, not add-on) suits TN or TT systems where you need both overcurrent and ground-fault protection in one package.
Deployment context
Mounts on a backplate (fixed mounting, not DIN rail) with front connections both top and bottom. Pollution degree 3 per IEC 60947 covers industrial atmospheres with conductive or dry non-conductive pollution, typical of most control rooms and switchgear enclosures. The toggle handle provides positive contact indication — you can see and feel the contact position, which simplifies lockout/tagout verification.
Certified to GB/T 14048.2, EN/IEC 60947-2, and JIS C8201-2-2. The IEC 60947-2 listing covers the breaking capacity ratings and the isolation suitability mark — the breaker is certified for use as a disconnecting means (isolation function) per that standard. The IK07 impact rating (per EN 50102) means the enclosure withstands a 2 J impact, typical for industrial switchgear.
