CH222B Fuse Holder Cartridge 600V 100A DIN Rail

Part Overview

The CH222B is a cartridge fuse holder manufactured by Eaton - Bussmann Electrical Division, designed for 22mm x 58mm cartridge fuses with a 100A current rating and 600V voltage specification. This component is mounted on DIN rail and features a 2-circuit configuration with screw terminal connections.

The CH222B is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for replacement and new installations where this specification is required.

Key Parameters

Substitute Part Grouping Explanation

The CH222DU qualifies as a direct substitute for the CH222B based on the following critical parameters that determine functional compatibility:

• Fuse size: Both accept 22mm x 58mm cartridge fuses
• Current rating: Both rated for 100A
• Number of circuits: Both feature 2-circuit configuration
• Mounting type: Both mount on DIN rail
• Fuse type: Both are cartridge fuse holders
• Termination style: Both use screw terminals
• Manufacturer: Both manufactured by Eaton - Bussmann Electrical Division

The CH222DU is an active product with improved voltage rating (700V versus 600V) and RoHS compliance, making it suitable for direct replacement in applications requiring the CH222B specification.

Parameter Comparison

Engineering Selection Recommendations

The CH222DU is the direct substitute for the CH222B. Selection is based on the following factors:

• Product status: CH222B is obsolete; CH222DU is active and currently manufactured
• Electrical compatibility: CH222DU maintains the same 100A current rating and 2-circuit configuration, with an increased voltage rating of 700V that exceeds the original 600V specification
• Compliance: CH222DU is RoHS compliant, meeting current regulatory requirements
• Physical compatibility: Identical fuse size (22mm x 58mm), mounting type (DIN rail), and termination style (screw terminal) ensure direct mechanical and electrical fit

Frequently Asked Questions (FAQ)

Q: Can CH222DU replace CH222B in existing installations?

A: Yes. The CH222DU is electrically and mechanically compatible with the CH222B. Both holders accept the same 22mm x 58mm cartridge fuses, operate at 100A, feature 2-circuit configuration, and mount identically on DIN rail with screw terminals. The CH222DU's higher 700V rating provides additional margin over the original 600V specification.

Q: What is the difference between CH222B and CH222DU?

A: The primary differences are product status and voltage rating. CH222B is obsolete and rated for 600V, while CH222DU is an active product rated for 700V. CH222DU is also RoHS compliant. All other electrical and mechanical parameters are identical.

Q: Are the fuse cartridges interchangeable between CH222B and CH222DU?

A: Yes. Both holders accept 22mm x 58mm cartridge fuses. Any cartridge fuse meeting this size specification and appropriate current/voltage rating can be used in either holder.

Q: What packaging is available for CH222DU?

A: CH222DU is available in bulk packaging.
