SU1C3AC Equivalent & Substitute Parts

Part Overview

The SU1C3AC is a single-pole circuit breaker with C-curve characteristic and 3A current rating manufactured by Weidmüller. This component is classified as obsolete, requiring identification of active equivalent models for continued system design and maintenance applications. The part operates across AC and DC voltage ranges suitable for industrial control and distribution circuits. Obsolescence necessitates sourcing of functionally equivalent active alternatives to maintain supply chain continuity and ensure design compatibility in new installations and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SU1C3AC is determined by the following critical parameters derived from the provided data:

Current Rating: 3A — The substitute must maintain identical current protection threshold.

Pole Configuration: Single-pole (1P) — The substitute must provide equivalent single-pole switching and protection.

Curve Characteristic: C-curve — The substitute must exhibit identical thermal-magnetic trip characteristics for C-curve applications.

Voltage Ratings: AC and DC voltage compatibility — The substitute must support equivalent voltage ranges for both AC and DC operation.

Mounting and Actuation: DIN Rail mounting with lever actuation — The substitute must use compatible mechanical interface and control mechanism.

Regulatory Compliance: REACH and export classification alignment — The substitute must maintain equivalent compliance status.

The substitute part 2480050000 satisfies these criteria through matching current rating, pole count, curve type, voltage specifications, and mounting standard, while maintaining active product status and current regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The part 2480050000 is the designated active equivalent for the obsolete SU1C3AC based on the following engineering criteria:

Functional Equivalence: Both parts share identical current rating (3A), pole configuration (1P), and thermal-magnetic protection characteristic. The substitute maintains the same protective function within equivalent voltage and current operating ranges.

Regulatory Compliance: The substitute carries multiple international approvals (CE, CSA, TUV, UL1077, VDE) and maintains RoHS compliance, ensuring suitability for current regulatory environments. Both parts share identical ECCN and HTSUS classification, confirming export and tariff equivalence.

Supply Status: The substitute is in active production with confirmed inventory availability (1224 Pcs), whereas the original part is obsolete. Selection of the active equivalent ensures long-term supply chain continuity and eliminates obsolescence risk.

Mechanical Compatibility: DIN Rail mounting with lever actuation provides standard industrial interface compatibility for panel and distribution applications.

Frequently Asked Questions (FAQ)

Q: Can 2480050000 directly replace SU1C3AC in existing installations?

A: Yes. Both parts are single-pole, 3A thermal-magnetic circuit breakers with C-curve characteristics from the same manufacturer. Mechanical mounting (DIN Rail) and electrical function are equivalent. Physical form factor and terminal configuration must be verified against the specific installation geometry.

Q: What are the key parameters that define substitution eligibility?

A: Current rating (3A), pole count (1), curve type (C-curve thermal-magnetic), voltage compatibility (AC/DC ranges), and mounting standard (DIN Rail) are the primary substitution criteria. All these parameters match between the obsolete and active parts.

Q: Does the substitute meet the same regulatory requirements?

A: The substitute carries broader regulatory approvals (CE, CSA, TUV, UL1077, VDE) compared to the original part specification. Both maintain identical ECCN (EAR99) and HTSUS (8536.20.0020) classification. The substitute is RoHS compliant, meeting current environmental standards.

Q: What is the packaging difference between these parts?

A: The original part SU1C3AC packaging is listed as "-" (not specified). The substitute 2480050000 is supplied in Bulk packaging. Bulk packaging is standard for DIN Rail circuit breakers and does not affect electrical or mechanical function.

Q: Are there any voltage rating differences I should consider?

A: The substitute specifies 277 V AC and 60 V DC ratings. The original part voltage ratings are not provided in the available data. The specified ratings for the substitute are typical for industrial single-pole circuit breakers in this current class and are suitable for standard control and distribution applications.

Q: What is the moisture sensitivity level for both parts?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components are suitable for standard industrial environments without special moisture control requirements during storage or handling.
