Parameter Category Specification Assembly Type LV Switchgear Functional Unit / Feeder Compartment Standard IEC 61439-1 & -2 Internal Separation Form 1 (F1) - Common compartment for busbars, breaker, and terminals. Busbar System • Rated Current (Ibm): 1600 A • Short-Time Withstand (Icw): Typically 50-65 kA for 1s (Design dependent) • Peak Withstand (Ipk): ~2.2 x Icw Main Protective Device • Type: ABB SACE Emax E1/E2 Frame, Draw-out Air Circuit Breaker. • Likely Rated Current (In): 1600A (E1.4 or E2.1 frame). Could be 1250A depending on design. • Poles: 3 • Trip Unit: Electronic (PR1 series - e.g., PR121/P). Typically provides LSI protection. • Breaking Capacity (Icu): Typically 50 kA (H) or 65 kA (N) at 400V AC, depending on specific breaker order. Key Breaker Features • Draw-out (W) for isolation, testing, and easy maintenance. • Electric Charging Motor (M) for automatic spring recharge. • Shunt Trip (MX) (P) for remote electrical tripping. Typical Additional Breaker Accessories • Auxiliary Contacts (OF/SD) for status signaling - Highly likely included but not in code; must verify. • Undervoltage Release (MN) - May or may not be included; must verify. Control Voltage Motor and shunt trip require an auxiliary control supply (e.g., 110V/220V DC or 230V AC). Must be specified separately. Physical Configuration One vertical compartment in a switchboard, including: • Draw-out breaker truck with guides and shutters. • Busbar connections. • Cable connection chamber (typically rear or bottom). • Door with possible control elements (buttons, indicators). IP Rating (Enclosure) Typically IP31, IP41, or IP54.
