3WA1116-3AB03-4KA0-Z C01 SIEMENS

The 3WA1116-3AB03-4KA0-Z C01 circuit breaker from Siemens is a robust and reliable solution for power distribution systems. This fixed-mounted circuit breaker is designed according to IEC 60947-2 standards, ensuring compliance with international safety and performance requirements. With a frame size of 1 and a 3-pole configuration, it is suitable for applications up to 690V AC at 50/60Hz. The circuit breaker has a rated current (In) of 1600A, making it capable of handling substantial electrical loads. Its breaking capacity S, with Icu values of 66kA at 500V and 50kA at 690V, provides effective protection against short-circuit faults. The ETU300 trip unit offers LSI protection functions, optimized for standard applications, and does not include a display. Protection features include LT (Long Time), ST (Short Time), and INST (Instantaneous) protection, with N-protection requiring an external N-sensor. It includes a trip alarm switch (1xCO), front connection with a double hole, and lacks communication and metering functions. The device is equipped with both manual and motorized operating mechanisms (M) that operate at 208-240 V AC / 220-250 V DC, along with storage status and ready-to-close signaling switches, auxiliary switches (2NO+2NC), and a closing coil (CC) 5% OP 24-30 V DC for momentary duty, and option C01 which is an operations counter for the circuit breaker.
