BCH series AC Contactor is widely used for household electrical appliances control. Modular AC Contactor is used for remote control switch on and switch off the household electrical appliances which no inductance or with lower inductance loading. Such as electromagnetic oven, motors and other electrical appliances.
Modular AC Contactor mainly used in
AC50Hz/60Hz,rated voltage to 400V,rated current of power system to
100A,AC-1,AC-7a (in no inductance or lower inductance load, resistance furnace,
household appliances and similar lower inductance load) categories. Long
distance switch and control circuit. House use AC Contactor is not used for
breaking short circuit current, so it is necessary to choose suitable circuit
protection electrical equipment for short circuit protection.

**Even Campus Network**
The campus network is a broadband, multimedia-based system designed to support teaching, research, and integrated information services for both faculty and students. First and foremost, it should provide an advanced digital learning environment that enhances the educational experience. This requires the campus network to be a high-speed, interactive, and specialized local area network. Features such as a multimedia teaching platform, smart classrooms, teacher preparation systems, electronic libraries, and comprehensive teaching and examination databases can all function seamlessly over this network. If a university has multiple departments or disciplines, separate local networks can be created and connected via wired or wireless means. In addition, the campus network must also support administrative functions, including management, communication, and general operations.
**IPv6**
IPv6 is the next-generation Internet Protocol, designed to replace IPv4, which is currently in widespread use. IPv4 uses 32-bit addresses, limiting the number of available IP addresses. As the global internet continues to expand, the scarcity of IPv4 addresses has become a significant challenge. IPv6, with its 128-bit addressing format, offers a vast number of unique IP addresses, along with enhanced security, mobility, and improved quality of service. These advantages make IPv6 a crucial step toward supporting the growing demands of modern digital life.
Although IPv6 is not yet widely commercialized, it is being deployed in major universities as part of their infrastructure. One reason for this is that many institutions have adopted IPv6 to bypass the limitations of IPv4 billing systems. In practice, users communicate with IPv6 servers using the IPv6 protocol, while the server itself accesses the IPv4 network to retrieve content for the user.
**Where is Our Server?**
Our servers are located in Beijing and Wuhan, ensuring low latency and fast response times compared to foreign servers. This makes accessing international websites like YouTube or Facebook smoother and more efficient.
**Can I Access Facebook, YouTube?**
Yes, you can access platforms like YouTube and enjoy 1080p video streaming without any issues.
**What Is the Bandwidth Speed?**
Our servers offer unlimited bandwidth, and your actual speed depends on your school’s connection. For example, 1 Mbps equals 128 KB/s. You can test your speed at [neu.speed.neu6.edu.cn](http://neu.speed.neu6.edu.cn).
**Can the Network Be Shared?**
Yes, you can share the network by enabling Wi-Fi on your computer.
**Can It Be Used on a Router?**
You can use your account on OpenWRT routers, but due to variations in hardware and firmware, the configuration may differ. We provide a common configuration file, but you will need to configure it yourself.
**Can I Use It at Home or On Campus?**
Yes, with IPv6 support, you can access the campus network freely. Even when you're off-campus, using our account allows you to access IPv6, giving you unrestricted access to foreign websites like Google, YouTube, and others.
**Do I Have an IPv6 Network?**
To check if your device supports IPv6, go to "Network and Sharing Center" > "Change Adapter Settings" > right-click your connection > "Properties" > make sure IPv6 is checked. If you’re unsure, refer to the tutorial in Appendix 1.
**How to Enable IPv6**
1. Right-click the network icon in the taskbar (bottom right corner).
2. Select “Open Network and Sharing Center.â€
3. Click on your active connection (e.g., Ethernet or Local Area Connection).
4. Click “Properties.â€
5. Uncheck IPv4 and ensure IPv6 is selected.
6. Click “Internet Protocol Version 6 (TCP/IPv6)†and set the preferred DNS to `2001:778::37`.
7. Click OK and wait for the connection to establish. Some systems may require a restart.
After enabling IPv6, you can test it by visiting [ipv6.jmu.edu.cn](http://ipv6.jmu.edu.cn), where you should see a tiger. If it works, you can access IPv6-enabled websites like [tv.byr.cn](http://tv.byr.cn) for IPTV services.
