TPS-60L 60A 170VDC Cylindrical Fuse Cartridge Equivalent & Substitute Parts

Part Overview

The TPS-60L is a 60A 170VDC cylindrical fuse cartridge manufactured by Eaton - Bussmann Electrical Division, part of the Telpower® TPS series. This component is designed for bolt mount applications in telecom systems. The product is currently obsolete, making equivalent substitute parts necessary for system maintenance, repair, and replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TPS-60L is determined by strict equivalence across the following electrical and mechanical parameters:

• Current Rating: 60A
• Voltage Rating (DC): 170 VDC
• Fuse Type: Cartridge
• Mounting Type: Bolt Mount
• Package / Case: Cylindrical, Blade Terminal (Bolt)
• Breaking Capacity @ Rated Voltage: 100kA

The identified substitute parts are from Littelfuse Inc., POWR-GARD® TLS series. Both substitute parts (0TLS060.TXL and 0TLS060.TXLB) meet all critical electrical parameters and mechanical mounting requirements. These parts are active products with current manufacturing status, providing long-term availability for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

Both Littelfuse POWR-GARD® TLS series parts (0TLS060.TXL and 0TLS060.TXLB) are direct electrical equivalents to the obsolete TPS-60L. Selection between the two substitute options should be based on physical space constraints within the installation, as they differ in length dimensions while maintaining identical electrical characteristics and bolt mount compatibility.

The substitute parts carry active product status, ensuring continued availability and manufacturing support. Both parts hold CE and cURus certifications, meeting regulatory requirements for telecom applications. The ROHS3 compliance of the substitute parts provides additional environmental compliance benefits over the original obsolete component.

Frequently Asked Questions (FAQ)

Q: Can 0TLS060.TXL and 0TLS060.TXLB be used interchangeably with TPS-60L?

A: Both Littelfuse parts are electrically equivalent to the TPS-60L across all critical parameters: 60A current rating, 170VDC voltage rating, 100kA breaking capacity, and bolt mount cylindrical configuration. Physical dimensions differ between the two Littelfuse options, so installation space must be verified before selection.

Q: What is the primary difference between 0TLS060.TXL and 0TLS060.TXLB?

A: The parts are electrically identical. The difference is physical length: 0TLS060.TXL measures 1.740" (44.20mm) while 0TLS060.TXLB measures 1.580" (40.13mm). Both maintain the same 0.563" (14.30mm) diameter and blade terminal bolt mount configuration.

Q: Why is the TPS-60L obsolete?

A: The TPS-60L is listed as obsolete by the manufacturer. The identified Littelfuse substitutes provide equivalent electrical performance and are active products with current manufacturing support.

Q: Are the substitute parts certified for telecom applications?

A: Both substitute parts carry CE and cURus certifications. They are specified for telecom applications and meet the same regulatory requirements as the original TPS-60L.

Q: Will the substitute parts fit in the same mounting location as the TPS-60L?

A: The bolt mount configuration and diameter are identical. However, the TPS-60L length (0.874") differs from both substitute parts (1.740" and 1.580"). Physical space verification is required before installation to confirm fit within the existing mounting structure.
