Altech Corporation 3CU30L Circuit Breaker - Equivalent & Substitute Parts

Part Overview

The Altech Corporation 3CU30L is a thermal-magnetic circuit breaker rated for 30A at 480V AC/DC with lever actuation and DIN rail mounting. This component is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing system maintenance and new installations. The 3CU30L remains available in inventory (1107 pcs) but active substitute options should be evaluated for long-term supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3CU30L is determined by strict equivalence across the following critical parameters:

• Current Rating: 30A (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: 3 (exact match required)
• Approval Agencies: CE, cULus, UL489 (minimum compliance required)

The 3C30UL meets all substitution criteria as an active product from the same manufacturer with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The 3C30UL is a direct functional equivalent to the 3CU30L. Both components share identical electrical ratings (30A, 480V AC), mechanical configuration (3-pole, lever-actuated, DIN rail mount), and regulatory compliance (CE, cULus, UL489). The 3C30UL holds active product status with current inventory availability (1151 pcs), making it the appropriate selection for applications requiring the 3CU30L specification. Compliance certifications are equivalent across both parts, supporting direct substitution in existing designs and new installations.

Frequently Asked Questions (FAQ)

Q: Can the 3C30UL be used as a direct replacement for the 3CU30L?

A: Yes. Both parts are 30A, 480V AC, 3-pole thermal-magnetic circuit breakers with lever actuation and DIN rail mounting. All electrical and mechanical parameters are identical, and both hold equivalent regulatory approvals (CE, cULus, UL489).

Q: What is the difference between the 3CU30L and 3C30UL?

A: The primary difference is product status. The 3CU30L is discontinued at DiGi Electronics, while the 3C30UL remains active. The series designation differs (L vs. UL), but all functional specifications are equivalent.

Q: Are there packaging differences between these parts?

A: The 3CU30L is supplied with standard packaging, while the 3C30UL is supplied in bulk packaging. This does not affect electrical or mechanical performance.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 3CU30L and 3C30UL carry CE, cULus, and UL489 approvals. Both are ROHS3 compliant and REACH unaffected.

Q: Which part should be selected for new designs?

A: The 3C30UL should be selected for new designs due to its active product status and current availability. It provides identical functionality to the 3CU30L with assured supply chain continuity.
