SPP-4M60 Equivalent & Substitute Parts

Part Overview

The SPP-4M60 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 60A at 700V operation. This component is part of the Semitron™ SPP series and requires an external holder for installation. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance and component replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

The 170M3560 is identified as a substitute for the SPP-4M60 based on the following electrical and mechanical compatibility criteria:

• Voltage Rating Compatibility: Both components operate at voltages within the same classification range (700V and 690V respectively), suitable for equivalent circuit protection applications
• Current Rating Proximity: The 170M3560 is rated at 63A, providing current protection in the same operational band as the 60A SPP-4M60
• Mounting Configuration: Both components require external holders, ensuring mechanical compatibility in existing installations
• Manufacturer Consistency: Both are manufactured by Eaton - Bussmann Electrical Division, maintaining supply chain and quality standards
• Regulatory Classification: Both components share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications

Parameter Comparison

Engineering Selection Recommendations

The 170M3560 is an active product with current manufacturing support and RoHS compliance certification. As the SPP-4M60 is obsolete, the 170M3560 provides continuity for circuit protection requirements in applications requiring 60A-class fusing at voltages up to 700V. Both components share identical regulatory classifications and are supplied by the same manufacturer, supporting standardized procurement and inventory management.

Frequently Asked Questions (FAQ)

Q: Can the 170M3560 directly replace the SPP-4M60 in existing installations?

A: Both components require external holders and share compatible voltage and current ratings within the same operational classification. Physical form factor differences (Fuse Link versus Square) must be verified against the specific holder design in your application.

Q: What is the significance of the current rating difference (60A vs. 63A)?

A: The 63A rating of the 170M3560 provides equivalent or slightly higher protection capability. This 3A difference falls within standard fuse rating classifications and does not alter the fundamental protection function for 60A-class circuits.

Q: Why is RoHS compliance listed only for the 170M3560?

A: The SPP-4M60 is an obsolete product with historical manufacturing records. The 170M3560, as an active product, carries current RoHS compliance certification.

Q: Are there any packaging considerations for procurement?

A: The SPP-4M60 was supplied in standard packaging, while the 170M3560 is available in bulk packaging. Verify minimum order quantities and lead times with your supplier based on your application requirements.

Q: Do both fuses have the same response time characteristics?

A: The SPP-4M60 response time is not specified in available documentation. The 170M3560 is rated as Fast Blow. Application requirements for response time should be evaluated against your circuit protection specifications.
