Technical Data: Series: Emax 4 (E4) - Top-tier series for ultra-high current applications. Frame Size: S - Largest physical frame in the Emax 4 range. Rated Current (In): 4000 A (The maximum continuous current rating of the breaker's main bus system and contacts). Rated Ultimate Breaking Capacity (Icu): 150 kA at 400/415V AC *(Note: This is a typical high value for the E4S frame; the definitive Icu/Ics must be verified from the Emax 4 catalog, as it can be 150kA or 200kA depending on the specific certified configuration)*. Number of Poles: 3 Poles (3P - phases L1, L2, L3). Trip Unit: Standard Fixed Protection (Implicit in code). The "P" in the code indicates it is equipped with a "PR332" series basic fixed protection trip unit. This is a non-adjustable, non-communicating electronic unit. Protection: It provides fundamental fixed Long-time (L) and Short-time (S) protection with factory-set thresholds based on the 4000A frame rating. It typically does not include an Instantaneous (I) or Ground-fault (G) function as standard, which is suitable for coordination in high-power selective systems. Mounting & Operation: Fixed Horizontal Draw-Out (WMP). "WMP" is a specific draw-out mechanism code, indicating a robust rack-in/rack-out cradle design. The breaker is fixed to the cradle, and the entire cradle assembly can be moved horizontally into the CONNECTED, TEST, or DISCONNECTED positions. Features a motor-operated stored-energy spring mechanism for reliable high-speed closing and tripping. Equipped with a spring charging motor and a closing solenoid as standard for electrical remote operation. Rated Operational Voltage (Ue): Up to 690 V AC, 50/60 Hz. Control Voltage: Standard auxiliary supply voltage is typically 110-240V AC/DC (specifics defined at order). Standards Compliance: IEC/EN 60947-2, UL 1066, CSA C22.2 No. 5, and other international standards.
