SU2C10AC Equivalent & Substitute Parts

Part Overview

The SU2C10AC is a 2-pole circuit breaker with C-curve characteristic and 10A current rating manufactured by Weidmüller. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance and component procurement. The part operates across AC and DC voltage ranges and is designed for DIN rail mounting applications. Due to its obsolete status, sourcing direct replacements requires evaluation of active alternatives that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SU2C10AC is determined by alignment of the following critical parameters:

• Current Rating: 10A (exact match required)
• Number of Poles: 2 (exact match required)
• Breaker Characteristic: C Curve (exact match required)
• Voltage Ratings: AC and DC capability (480V AC / 125V DC minimum)
• Mounting Standard: DIN Rail compatibility
• Regulatory Compliance: CE, CSA, TUV, UL1077, VDE certifications
• Product Status: Active alternatives preferred for ongoing availability

The substitute part 2480340000 meets all critical electrical parameters and maintains regulatory compliance through multiple international standards. This part is currently active in inventory, addressing the obsolescence constraint of the original component.

Parameter Comparison

Engineering Selection Recommendations

The 2480340000 is a direct functional substitute for the SU2C10AC based on the following criteria:

• Both components are manufactured by Weidmüller, ensuring design consistency and quality standards
• Electrical ratings are identical: 10A, 2-pole configuration with C-curve thermal-magnetic protection
• The substitute part is currently active in production, eliminating obsolescence risk
• Regulatory certifications (CE, CSA C22.2 No 5, CSA C22.2 No 235, TUV, UL1077, VDE) confirm compliance with international safety standards
• RoHS compliance of the substitute part meets modern environmental regulations
• DIN rail mounting and lever actuator provide mechanical compatibility with existing installations
• Voltage ratings (480V AC / 125V DC) exceed typical industrial application requirements

Selection of part 2480340000 is supported by product availability (824 pcs in stock) and active product status, ensuring long-term supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the 2480340000 directly replace the SU2C10AC in existing installations?

A: Yes. Both parts share identical current ratings (10A), pole configuration (2-pole), and breaker characteristic (C-curve). The substitute maintains DIN rail mounting compatibility and lever actuation. Voltage ratings of the substitute (480V AC / 125V DC) accommodate standard industrial applications.

Q: What is the difference between C-curve and thermal-magnetic protection?

A: C-curve is a specific thermal-magnetic characteristic curve that defines the trip point and response time of the breaker. The 2480340000 uses thermal-magnetic technology to implement the C-curve characteristic, providing equivalent protection performance.

Q: Are there compliance differences between the two parts?

A: No. Both parts carry EAR99 ECCN classification and MSL 1 (Unlimited) moisture sensitivity rating. The substitute part adds RoHS compliance certification, which represents an enhancement for modern regulatory requirements.

Q: What packaging differences exist?

A: The SU2C10AC is listed with "-" packaging notation. The 2480340000 is supplied in bulk packaging, standard for DIN rail-mounted industrial components. This does not affect functional compatibility.

Q: Why is the SU2C10AC obsolete?

A: Product obsolescence is determined by manufacturer discontinuation. The 2480340000 represents the active equivalent in the Weidmüller product line, specifically within the MCB 1077 series.
