Weidmüller 991306 Circuit Breaker - Equivalent & Substitute Parts

Part Overview

The Weidmüller 991306 is a thermal magnetic circuit breaker rated for 600mA at 480V AC and 65V DC, designed for DIN rail mounting with lever actuation. This component is classified as obsolete, making identification of active equivalent parts essential for system maintenance and component replacement in industrial control applications.

The obsolete status necessitates sourcing from available inventory or identifying functionally equivalent active alternatives to ensure continued availability and supply chain reliability.

Substitute Part Grouping Explanation

Substitution of the Weidmüller 991306 is determined by strict equivalence across the following critical parameters:

• Current Rating: 600mA (exact match required)
• Voltage Rating - AC: 480V (exact match required)
• Voltage Rating - DC: 65V (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Number of Poles: 3 (exact match required)
• Actuator Type: Lever (exact match required)
• Series: CB2200 (same product family)

The substitute part 9913060003 maintains identical electrical and mechanical specifications, differing only in product status (active vs. obsolete) and packaging configuration (bulk vs. standard).

Parameter Comparison

Engineering Selection Recommendations

The substitute part 9913060003 is a direct functional equivalent to the obsolete Weidmüller 991306. Both components share identical electrical ratings, mechanical specifications, and regulatory certifications (CSA C22.2 No 235, UL1077, VDE).

Selection of part 9913060003 is appropriate for applications requiring replacement of the 991306, as it maintains full compliance with the same approval standards and RoHS requirements. The active product status of 9913060003 ensures ongoing availability and supply chain continuity.

Packaging differences (bulk vs. standard) do not affect functional compatibility and are determined by procurement requirements rather than technical specifications.

Frequently Asked Questions (FAQ)

Q: Can part 9913060003 directly replace the obsolete 991306?

A: Yes. Both parts are identical in all critical electrical and mechanical parameters: 600mA current rating, 480V AC / 65V DC voltage ratings, thermal magnetic operation, 3-pole lever-actuated DIN rail mounting, and regulatory certifications.

Q: What is the difference between these two part numbers?

A: The primary differences are product status (991306 is obsolete; 9913060003 is active) and packaging configuration (standard vs. bulk). Electrical and mechanical specifications are identical.

Q: Are the regulatory certifications the same?

A: Yes. Both parts carry identical approvals: CSA C22.2 No 235, UL1077, and VDE. Both are RoHS Compliant.

Q: Does packaging affect compatibility?

A: No. Packaging differences relate to order quantity and logistics only. The component itself is functionally identical regardless of packaging configuration.

Q: Is the 9913060003 suitable for new designs?

A: Yes. As an active product in the CB2200 series with full regulatory certifications, part 9913060003 is suitable for both replacement and new design applications.
