SIEMENS WLETU776跳闸装置 英文介绍

SIEMENS WLETU776 is an electronic trip unit specifically designed for Siemens WL series circuit breakers. It uses a graphical LCD display screen to provide precise overload and short circuit protection for low-voltage distribution systems.

Provide four protection functions for LSIG: long delay, short delay, instantaneous, and ground fault protection.

Equipped with a graphical LCD display screen, real-time measurement data such as current, voltage, and power can be viewed.

The rated current range is 200A to 5000A, and it needs to be used in conjunction with the corresponding current transformer plug.

Suitable for low voltage circuit breakers with a voltage of 600V and a 3-pole configuration.

Compliant with UL 489 and UL 1066 standards, certified by UL in the United States.

Supports Modbus RTU communication protocol and can be integrated into SCADA or DCS systems.

The tripping response time can be configured, and the protection curve can be intuitively set through the LCD panel.

Built in event recording function, which can record fault waveforms with timestamps for easy fault analysis.

Compatible with multiple WL series frameworks, including WLS, WLH, WLL, WLC, and other models.

Adopting electronic solid-state design, with high measurement accuracy and low maintenance requirements.

The front panel is equipped with LED status indicator lights, making the operation and fault status clear at a glance.

Optional PROFINET communication module to meet industrial Ethernet integration requirements.

The working temperature range is -25 ℃ to+70 ℃, suitable for harsh industrial environments.

Made in Germany, with a net weight of approximately 2.2 pounds (about 1 kilogram).

Support interchangeable installation, which can be upgraded or replaced without modifying the circuit breaker body.

In summary, the SIEMENS WLETU776 electronic trip unit provides high-precision intelligent protection solutions for industrial and commercial power distribution systems with its LSIG full function protection, graphical interface, and flexible communication capabilities.
