Circuit Breaker Thermal Magnetic 2CU10L - Equivalent & Substitute Parts

Part Overview

The Altech Corporation 2CU10L is a thermal magnetic circuit breaker rated for 10A at 480V AC and 250V DC, designed for DIN rail mounting with lever actuation. This component is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives to maintain system continuity and procurement flexibility. The 2CU10L remains available in inventory (785 pcs) but active substitute options provide ongoing supply assurance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2CU10L is determined by the following critical parameters:

• Current Rating: 10A (exact match required)
• Voltage Rating - AC: 480V (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Actuator Type: Lever (exact match required)
• Number of Poles: 2 (exact match required)
• Approval Agencies: CE, cULus, UL489 (must include all three certifications)

The 2C10UL meets all substitution criteria. While the 2C10UL does not specify a DC voltage rating in the provided data, it maintains identical AC voltage rating, current capacity, breaker topology, mounting configuration, and regulatory approvals. Both parts share the same base product number (2C10 vs. 2CU10), indicating common design lineage within the Altech thermal magnetic breaker family.

Parameter Comparison

Engineering Selection Recommendations

The 2C10UL is a direct functional equivalent for the 2CU10L in applications requiring a 10A thermal magnetic circuit breaker at 480V AC on a DIN rail with lever actuation. Both parts carry identical regulatory approvals (CE, cULus, UL489) and maintain ROHS3 compliance. The 2C10UL offers the advantage of active product status with higher inventory availability (980 pcs vs. 785 pcs), supporting long-term procurement continuity. Selection between these parts should be based on application-specific DC voltage requirements, as the 2CU10L explicitly specifies 250V DC capability while the 2C10UL data does not include DC rating specification.

Frequently Asked Questions (FAQ)

Q: Can the 2C10UL replace the 2CU10L in all applications?

A: The 2C10UL matches all specified AC electrical parameters, mounting configuration, and regulatory certifications. Substitution is appropriate for 480V AC applications. For circuits requiring DC operation at 250V, the absence of DC rating specification in the 2C10UL data requires clarification with the manufacturer before substitution.

Q: What is the significance of the series designation change from "L" to "UL"?

A: The series designation reflects internal Altech product line organization. Both parts share the base product number (2C10), indicating they belong to the same thermal magnetic breaker family. The series change does not affect electrical performance or mechanical compatibility for the specified parameters.

Q: Are there packaging differences between these parts?

A: The 2CU10L is specified with "-" packaging notation, while the 2C10UL is supplied in Bulk packaging. Both are DIN rail mounted components; packaging designation refers to distribution format rather than physical form factor.

Q: Why is the 2CU10L discontinued if the 2C10UL is available?

A: Product discontinuation reflects manufacturer and distributor portfolio decisions. The 2C10UL represents the active continuation within the Altech thermal magnetic breaker line, offering equivalent functionality with ongoing supply assurance.

Q: What compliance certifications apply to both parts?

A: Both the 2CU10L and 2C10UL carry CE, cULus, and UL489 approvals, meeting European and North American regulatory requirements for circuit protection devices. Both maintain ROHS3 compliance and REACH unaffected status.
