Circuit Breaker Thermal Magnetic 30A Altech 2CU30L

Part Overview

The Altech 2CU30L is a thermal magnetic circuit breaker rated for 30A at 480V AC and 250V DC, designed for DIN rail mounting with lever actuation. This component is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing system maintenance and new installations. The 2CU30L remains available in inventory (779 pcs) but alternative models from the same manufacturer provide active product status and continued supply chain support.

Key Parameters

Substitute Part Grouping Explanation

The Altech 2C30UL qualifies as a direct substitute for the 2CU30L based on the following critical parameters:

• Current Rating: Both rated at 30A
• Voltage Rating - AC: Both rated at 480V
• Breaker Type: Both thermal magnetic
• Mounting Type: Both DIN rail mount
• Actuator Type: Both lever actuated
• Number of Poles: Both 2-pole configurations
• Approval Agencies: Both carry CE, cULus, and UL489 certifications
• RoHS Compliance: Both ROHS3 compliant

The primary difference is product status: the 2CU30L is discontinued while the 2C30UL maintains active status, ensuring continued availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

The 2C30UL is the appropriate substitute for the 2CU30L in applications requiring a 30A thermal magnetic circuit breaker with 480V AC rating and DIN rail mounting. Both components meet identical regulatory requirements (CE, cULus, UL489) and maintain ROHS3 compliance. The 2C30UL's active product status provides superior long-term supply chain assurance compared to the discontinued 2CU30L. Selection between these parts should prioritize the 2C30UL for new designs and ongoing procurement.

Frequently Asked Questions (FAQ)

Q: Can the 2C30UL directly replace the 2CU30L in existing installations?

A: Yes. Both components share identical current ratings (30A), AC voltage ratings (480V), breaker type (thermal magnetic), mounting configuration (DIN rail), pole count (2), and regulatory certifications (CE, cULus, UL489). Physical form factor and electrical performance are equivalent.

Q: What is the primary reason to substitute the 2CU30L?

A: The 2CU30L is discontinued at DiGi Electronics. The 2C30UL maintains active product status, ensuring continued availability and supply chain support for future orders and replacements.

Q: Are there voltage rating differences between these parts?

A: The 2CU30L specifies both 480V AC and 250V DC ratings. The 2C30UL documentation specifies 480V AC. For applications requiring DC voltage operation at 250V, verify the 2C30UL's DC rating with the manufacturer before substitution.

Q: Do packaging differences affect compatibility?

A: No. The 2CU30L uses standard packaging while the 2C30UL is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility in the installed application.

Q: Are both parts RoHS compliant?

A: Yes. Both the 2CU30L and 2C30UL are ROHS3 compliant and carry REACH Unaffected status, meeting current environmental and regulatory requirements.
