CH221BMS

CH221BMS is a type of fuseholder that provides protection for medium voltage electrical installations. It is designed for installations up to 1kV AC or 1.5kV DC. This type of fuseholder provides a high level of safety and is suitable for a wide range of applications.

The CH221BMS is designed for easy installation and maintenance and is UL listed for use in multiple systems. It is a double bolted fuseholder with two doors that are completely interlocked. This ensures that the circuit breaker cannot be opened when the fuseholder is closed. This also helps to reduce the risk of accidental arc flash.

The CH221BMS is equipped with a range of safety features to ensure maximum protection for the user. These include a safety bar to prevent accidental opening of the doors and a built-in surge protection circuit. It also features a dedicated grounding bar for easy grounding of the power system.

The CH221BMS is designed to work in a variety of environments. It is made from rugged construction materials and is suitable for both indoor and outdoor use. It is also designed to provide a high level of protection from electromagnetic interference.

The working principle of the CH221BMS is relatively simple. When the fuse is inserted, it is held in place by a spring-loaded lever. When the voltage reaches a predetermined level, the spring loaded lever is released and the fuse is broken. This causes the circuit to be interrupted, thus providing protection to the electrical system.

The CH221BMS is a reliable and cost-effective solution for providing protection to medium voltage electrical installations. It is designed to be easy to install and maintain and provides a high level of protection. It is suitable for a wide range of applications and is UL listed for use in multiple systems.
