CH222B

Fuseholders are mechanical devices designed to hold a fuse for protection, isolation, and safe operation of electrical circuits. The CH222B series of fuseholders from Eaton\'s Cooper Bussmann division is designed for use in medium voltage applications up to 600 volts. It is a special type of fuseholder that is used to protect both personnel and equipment from dangerous electrical faults. The CH222B fuseholder is designed to provide an easy and reliable way to install and maintain circuit protection fuses.

CH222B Application Field

The CH222B series is designed for use in circuit applications with external fault current ratings ranging from 7.5kA to 212.5kA. It is ideally suited for indoor and outdoor use in submersible pump applications and is UL rated, making it a safe and reliable option for use in hazardous areas. The CH222B is available in both pull-out and clip mount versions, and is designed to hold one or two circuit protection elements. The clip mount version is especially suitable for panel mounting applications where controllable access to the fuses is required.

CH222B Working Principle

The CH222B features a robust construction and utilizes the latest innovation technology to provide high levels of circuit protection. It consists of two screws that attach the fuseholder housing into the backing plate. Power is routed to the screws, which secure the fuse element. The fuse element consists of a core of heat-resistant material that is permanently charged with energy from the circuit. When the circuit is faulted, the energy released from the fuse element will intervene to switch the current off and prevent any further damage to the equipment or personnel.

Once the fault has been cleared, the CH222B is designed to reset and provide protection again. It is tested and approved to UL 508, CSA Standard 22.2 No. 235-95, and IEC 947-2 standards. This ensures that the CH222B is engineered to perform to the highest standards, giving you peace of mind that your circuit is properly protected.

Conclusion

The CH222B from Eaton’s Cooper Bussmann division is a robust fuseholder designed for medium voltage applications. It is UL rated and easy to install, providing reliable circuit protection for personnel and equipment. The CH222B utilizes the latest innovation technology to provide high levels of circuit protection. It is tested to the highest standards, giving you quality assurance that your circuit is properly protected.
