Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0CNN150E.H is determined by strict equivalence of electrical parameters: current rating (150A), DC voltage rating (80 VDC), response time classification (Fast Blow), and mechanical mounting interface (Bolt Mount). The substitute part 0CNN150E.HXU maintains these critical parameters while representing an active product in the POWR-GARD® CNN_E-U series. Both components satisfy the same electrical function within lift truck circuits and possess equivalent approval certifications.

Parameter Comparison

Engineering Selection Recommendations

The 0CNN150E.HXU is the designated manufacturer-recommended substitute for the obsolete 0CNN150E.H. Both components carry cURus approval and maintain equivalent electrical performance across the critical parameters: 150A current rating, 80 VDC operation, and Fast Blow response classification. The substitute part holds active product status, ensuring availability and continued manufacturer support. The increased breaking capacity (3kA versus 2.7kA) at rated voltage represents an enhanced capability within the same functional class. Selection between these components should be based on physical mounting geometry compatibility and circuit requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the 0CNN150E.HXU directly replace the 0CNN150E.H in existing applications? A: The 0CNN150E.HXU meets the electrical requirements of the 0CNN150E.H through equivalence of current rating, DC voltage rating, AC voltage rating, response time, and mounting type. Physical installation compatibility depends on the existing mechanical interface and package geometry of the lift truck circuit.

Q: What is the significance of the difference in breaking capacity? A: Both parts operate within the same electrical circuit protection function. The 0CNN150E.HXU provides a higher breaking capacity (3kA) compared to the original part (2.7kA), representing enhanced performance margin without affecting standard operation.

Q: Are there differences in package configuration between these parts? A: The original part uses a Metal Strip package, while the substitute specifies Cylindrical, Blade Terminal (Bolt) configuration. Both maintain Bolt Mount mechanical connection, but the physical form factor differs. Installation clearances and mounting hardware compatibility must be verified for the specific lift truck model.

Q: Do both parts carry the same approvals? A: Both the 0CNN150E.H and 0CNN150E.HXU carry cURus approval, satisfying equivalent regulatory compliance for electrical safety in their respective product statuses.

Q: Why is the AC voltage rating absent from the substitute part specification? A: The 0CNN150E.HXU is specified for 80 VDC operation without explicit AC voltage rating documentation. The substitute is classified for industrial and electrical applications with primary focus on DC operation, consistent with fork lift electrical systems.
