Eaton 170M1569 Square Fuse 160A 690VAC Equivalent & Substitute Parts

Part Overview

The Eaton 170M1569 is a square fuse rated for 160A at 690VAC, designed for industrial and electrical applications requiring high breaking capacity. This part is classified as obsolete, making identification of active equivalent models essential for procurement and system continuity. The 170M1569D serves as the direct active substitute, maintaining identical electrical and mechanical specifications while offering improved availability and current compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

The 170M1569D is classified as a direct substitute based on the following criteria:

• Current Rating Match: Both parts rated at 160A
• Voltage Rating Match: Both rated for 690VAC operation
• Fuse Type Match: Both are square fuses with identical form factor
• Mechanical Compatibility: Identical dimensions (53.00mm x 20.50mm x 52.00mm) and mounting requirements
• Electrical Performance: Matching breaking capacity (200kA) and melting I²t (2300)
• Package Compatibility: Both use rectangular blade package configuration

The substitution is valid because all critical electrical and mechanical parameters are identical between the main part and substitute.

Parameter Comparison

Engineering Selection Recommendations

The 170M1569D is the appropriate selection for applications currently using the 170M1569. Both parts are manufactured by Eaton - Bussmann Electrical Division and maintain identical electrical and mechanical specifications. The 170M1569D offers the advantage of active product status with expanded certification coverage (CE, CSA, UR versus UR only), providing enhanced compliance for international applications. The transition from the obsolete 170M1569 to the 170M1569D requires no circuit modifications or holder changes, as all critical parameters remain constant.

Frequently Asked Questions (FAQ)

Q: Can the 170M1569D directly replace the 170M1569 in existing installations?

A: Yes. The 170M1569D is a direct substitute with identical current rating (160A), voltage rating (690VAC), breaking capacity (200kA), physical dimensions, and mounting requirements. No modifications to fuse holders or circuit design are necessary.

Q: Are there any differences in certifications between these parts?

A: The 170M1569D carries expanded certifications (CE, CSA, UR) compared to the 170M1569 (UR only). This provides broader compliance for international and regional regulatory requirements.

Q: What is the significance of the product status change from Obsolete to Active?

A: The active status of the 170M1569D ensures ongoing availability, supply chain continuity, and manufacturer support. Obsolete parts face discontinuation risk and limited procurement options.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both parts measure 2.087" L x 0.807" W x 2.047" H (53.00mm x 20.50mm x 52.00mm) and use the same rectangular blade package configuration.

Q: Do both parts require the same fuse holder?

A: Yes. Both parts are square fuses requiring a compatible holder. No holder modifications are needed when transitioning from 170M1569 to 170M1569D.
