Altech Corporation 2CU5L Circuit Breaker - Equivalent & Substitute Parts

Part Overview

The Altech Corporation 2CU5L is a thermal-magnetic circuit breaker rated for 5A 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 for ongoing system maintenance and new installations. The 2CU5L remains available in inventory (1048 pcs) and maintains full compliance with CE, cULus, and UL489 standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2CU5L is determined by strict equivalence across the following parameters:

• Current Rating: 5A (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 certification (minimum requirement)

The 2C5UL meets all substitution criteria. Voltage Rating - DC is not specified for the 2C5UL in the provided data; however, all other electrical and mechanical parameters align with the 2CU5L requirements.

Parameter Comparison

Engineering Selection Recommendations

The 2C5UL is a direct functional equivalent to the 2CU5L for applications requiring a 5A, 480V AC thermal-magnetic circuit breaker with DIN rail mounting and lever actuation. Both components carry identical regulatory certifications (CE, cULus, UL489) and maintain ROHS3 compliance. The 2C5UL is currently in active production status with 892 pcs available in inventory, providing supply continuity for the discontinued 2CU5L. Selection between these parts should be based on availability, packaging requirements (2CU5L standard packaging vs. 2C5UL bulk packaging), and project lead time constraints.

Frequently Asked Questions (FAQ)

Q: Can the 2C5UL directly replace the 2CU5L in existing installations?

A: Yes. Both components share identical electrical ratings (5A, 480V AC), mechanical configuration (2-pole, lever-actuated, DIN rail mount), and thermal-magnetic protection characteristics. All regulatory certifications align.

Q: What is the difference between the 2CU5L and 2C5UL series designations?

A: The 2CU5L belongs to the L series, while the 2C5UL belongs to the UL series. Both are manufactured by Altech Corporation and meet the same UL489 standard. The series designation reflects internal product line organization but does not affect functional equivalence for the specified parameters.

Q: Is the 2C5UL suitable for DC applications?

A: The provided technical data does not specify a DC voltage rating for the 2C5UL. If DC operation at 250V is required, this parameter must be verified with the manufacturer before substitution.

Q: What packaging differences exist between these parts?

A: The 2CU5L is supplied in standard packaging, while the 2C5UL is supplied in bulk packaging. Packaging selection depends on order quantity and handling requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the 2CU5L and 2C5UL are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.
