Parameters: Parameter Value / Description Product Series Harmony WATSNB (Watertight Enclosure with Built-in Circuit Breaker) Main Device Integrated 400A Molded Case Circuit Breaker (MCCB) Rated Current (In) 400 A Number of Poles (Main) 4 (L1, L2, L3, N) - Providing full protection and isolation. Breaking Capacity (of MCCB) Depends on the specific breaker model integrated (e.g., likely Compact NSX400 with a standard or high breaking capacity). Configuration Code (4CBI) 4-Pole + Circuit Breaker + with Indicator Lights (typically for ON/OFF/TRIP status). Protection Rating (IP) IP65 (Dust-tight and protected against water jets) when closed. IP66 often available. Enclosure Material Polycarbonate (PC) or Stainless Steel (SS) – High impact, corrosion, and UV resistance. Mounting Surface mounting. Operation Manual handle operation for the integrated circuit breaker. Handle is typically removable for locking in OFF position. Status Indication Integrated pilot lights (as per “I” in code) to visually indicate the breaker’s status (e.g., Power ON, Trip). Control & Signaling May include auxiliary contacts (depending on exact configuration) for remote signaling. Standards IEC/EN 60947-2 (for the circuit breaker) & IEC/EN 60947-1 (for the enclosure). Typical Applications Main supply isolation and protection for outdoor pumps, large fans, compressor stations, marina power supplies, construction site distribution, and heavy machinery in wet/dusty areas.
