Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-7K1250 is based on the following critical electrical and mechanical parameters:

• Current Rating: 1.25kA (must match exactly)
• Voltage Rating: 700V AC (must match exactly)
• Mounting Type: Requires Holder (mechanical compatibility requirement)
• Manufacturer: Eaton - Bussmann Electrical Division (same manufacturer ensures design compatibility)
• RoHS Compliance: Required for regulatory alignment
• Regulatory Certifications: CSA and UR approvals provide equivalent safety validation

The substitute part 170M6516 satisfies all substitution criteria through matching current and voltage ratings, identical mounting requirements, and equivalent regulatory compliance status.
