Siemens Air Circuit Breaker Accessory 3WL9314-5AA00-0AA2 | ETU45B

1. Accessory Unit: Siemens 3WL9314-5AA00-0AA2

                      This module is an accessory for Siemens 3WL Air Circuit Breakers, specifically supporting the ETU45B electronic trip unit.

            Description: A configurable overcurrent release – ETU45B, Release 2 – providing adjustable LSIN (Long-time, Short-time, Instantaneous, Neutral) protection.

It comes without a rating plug, metering, display, or ground fault module, and includes CubicleBUS connection for integration.

                      Application: Designed for use in switchgear panels with a 3WL series breaker, enabling parameterization and CAN/Ethernet comms via CubicleBUS.

2. ETU45B Electronic Trip Unit

                        This module is the intelligent heart of the assembly: a microprocessor-based trip unit with adjustable protection characteristics.

Function: It provides advanced protection (LSI), overload, short-circuit, and neutral protection; adjustable via front-mounted rotary coding switches.

                   ETU45B also supports communication via CubicleBUS for remote settings, data logging, and integration with PROFIBUS/Ethernet systems.

                       Capabilities:

• Adjustable overload protection (e.g., 0.4-1 × In)
• Instantaneous trip settings and multiple time-lag options
• Optional add-ons: metering, display, communications—but the 5AA00 variant lacks these extras
