CH141B-PV Equivalent & Substitute Parts

Part Overview

The CH141B-PV is a cartridge fuse holder manufactured by Eaton - Bussmann Electrical Division, rated for 40 A at 600V with a single circuit configuration. Designed for DIN rail mounting, this component is classified as obsolete. Due to its obsolete status, identifying equivalent and substitute parts is necessary to maintain system functionality and ensure continued availability for replacement and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

The CHPV141U qualifies as a substitute for the CH141B-PV based on the following critical parameters:

• Mechanical compatibility: Both use 14mm x 51mm cartridge fuses
• Mounting configuration: Both mount on DIN rail with single circuit design
• Termination: Both employ screw terminal connections
• Manufacturer: Both are Eaton - Bussmann Electrical Division products within the CH series
• Fuse holder type: Both are cartridge fuse holders

The CHPV141U represents an active product alternative, addressing the obsolescence of the CH141B-PV while maintaining mechanical and electrical interface compatibility for the specified fuse cartridge format.

Parameter Comparison

Engineering Selection Recommendations

The CHPV141U is the designated substitute for the CH141B-PV. Selection of this alternative is supported by:

• Active product status ensuring ongoing availability and supply chain continuity
• RoHS compliance certification, meeting current regulatory requirements
• Identical mechanical interface and fuse cartridge compatibility
• Voltage and current ratings that exceed the original specification, providing operational margin
• Maintained screw terminal connection standard

The higher current rating (50 A vs. 40 A) and voltage rating (700V vs. 600V) of the CHPV141U do not compromise compatibility; these represent enhanced electrical capability within the same mechanical form factor.

Frequently Asked Questions (FAQ)

Q: Can the CHPV141U directly replace the CH141B-PV in existing installations?

A: Yes. Both components share identical mechanical dimensions (14mm x 51mm cartridge fuse format), DIN rail mounting, single circuit configuration, and screw terminal termination. The CHPV141U's higher ratings provide operational compatibility.

Q: What is the significance of the voltage and current rating differences?

A: The CHPV141U operates at 50 A and 700V compared to the CH141B-PV's 40 A and 600V. These higher ratings indicate enhanced electrical capability. In applications where the original 40 A / 600V specification is required, the CHPV141U remains compatible and suitable.

Q: Why is the CH141B-PV classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The CHPV141U represents the active alternative within the CH series, ensuring continued access to equivalent fuse holder functionality.

Q: Does RoHS compliance affect substitution?

A: The CHPV141U's RoHS compliance status meets current environmental and regulatory standards. This represents an improvement over the original part and does not impact mechanical or electrical compatibility.

Q: Are the fuse cartridges interchangeable between these two holders?

A: Yes. Both holders accept 14mm x 51mm cartridge fuses, maintaining standardized fuse compatibility across the product line.
