USCC3I Equivalent & Substitute Parts

Part Overview

The USCC3I is a 600V 30A 3-pole cartridge fuse holder with indicator manufactured by Mersen USA Newburyport-MA L.L.C. This component is classified as active product status and is ROHS3 compliant. The device is designed for industrial electrical distribution and protection applications requiring reliable cartridge fuse accommodation at 600V operating voltage with 30A current capacity across three circuits.

Alternative models become necessary when addressing specific application requirements such as DIN rail mounting compatibility, standardized fuse holder form factors, or when sourcing from alternative qualified manufacturers within the same electrical specification class.

Key Parameters

Substitute Part Grouping Explanation

The LPSC0003ZXID qualifies as an equivalent substitute based on the following critical parameters:

Voltage Rating: Both parts are rated for 600V operation, ensuring compatibility in the same electrical distribution systems.

Current Capacity: Both parts accommodate 30A current, maintaining identical load handling capability.

Circuit Configuration: Both parts provide 3-circuit (3-pole) functionality for three-phase or multi-circuit protection applications.

Fuse Type Classification: Both parts are cartridge fuse holders designed for Class CC fuses with standard 13/32" x 1-1/2" dimensions (10mm x 38mm).

Compliance Status: Both parts maintain ROHS3 compliance, satisfying modern environmental and regulatory requirements.

The LPSC0003ZXID introduces DIN rail mounting capability as an additional feature, which represents a functional enhancement rather than a deviation from the core electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the USCC3I and LPSC0003ZXID maintain active product status with ROHS3 compliance certification, confirming their suitability for current industrial applications. Selection between these parts should be based on mounting infrastructure requirements and termination interface compatibility within the target installation environment.

The LPSC0003ZXID POWR-GARD® series offers explicit DIN rail mounting specification, making it the appropriate choice for standardized industrial control panel installations utilizing DIN rail infrastructure. The USCC3I remains the specified component when existing mounting configurations or legacy system requirements mandate its use.

Both parts accept Class CC cartridge fuses with identical dimensional specifications, ensuring interchangeability at the fuse level regardless of holder selection.

Frequently Asked Questions (FAQ)

Q: Can the LPSC0003ZXID replace the USCC3I in existing installations?

A: Electrical compatibility is confirmed across all critical parameters: 600V voltage rating, 30A current capacity, and 3-circuit configuration. Physical installation compatibility depends on the mounting method of the existing installation. DIN rail mounting capability of the LPSC0003ZXID may require infrastructure modifications if the original installation uses alternative mounting methods.

Q: What fuse types are compatible with both holders?

A: Both the USCC3I and LPSC0003ZXID accommodate Class CC cartridge fuses with dimensions 13/32" x 1-1/2" (10mm x 38mm). Fuse selection must maintain the 30A current rating and 600V voltage rating to ensure proper system protection.

Q: Are there differences in termination methods between these parts?

A: The LPSC0003ZXID specifies screw terminal and pressure plate termination. The USCC3I termination method is not detailed in available specifications. Verify termination compatibility with the control circuit wiring and connection infrastructure before implementation.

Q: Do both parts meet current regulatory compliance requirements?

A: Yes. Both the USCC3I and LPSC0003ZXID maintain ROHS3 compliance status, confirming compliance with current environmental and hazardous substance restrictions applicable to electrical components.

Q: What is the inventory status for these parts?

A: The USCC3I has 727 pieces available. The LPSC0003ZXID has significantly higher availability at 100,399 pieces, which may influence lead time considerations for procurement planning.
