1C30UM 30A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 1C30UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 30A at 480V AC and 24V DC. This single-pole DIN rail-mounted breaker with lever actuation is part of the V-EA series and maintains active product status. Equivalent and substitute parts are identified based on matching electrical specifications, mechanical compatibility, and regulatory approvals to support procurement flexibility and inventory management.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1C30UM is determined by equivalence across the following critical parameters: current rating (30A), AC voltage rating (480V), DC voltage rating (24V), breaker type (thermal magnetic), mounting configuration (DIN rail), actuator mechanism (lever), pole count (1), series designation (V-EA), and regulatory certifications (CSA, UL508). All identified substitutes match these specifications without deviation. The substitutes differ only in their base product designation (1B30 and 1D30 versus 1C30), which reflects internal manufacturer classification within the same electrical and mechanical family.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—1C30UM, 1B30UM, and 1D30UM—are functionally equivalent for applications requiring a 30A thermal magnetic circuit breaker at 480V AC and 24V DC on DIN rail. Each part maintains active product status and carries identical CSA and UL508 certifications, confirming compliance with applicable safety standards. Selection among these equivalents may be based on inventory availability: 1C30UM (760 pcs), 1B30UM (917 pcs), or 1D30UM (668 pcs). All parts are supplied in bulk packaging and are ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can 1B30UM or 1D30UM be used as direct replacements for 1C30UM? A: Yes. Both 1B30UM and 1D30UM are parametric equivalents with identical electrical ratings (30A, 480V AC, 24V DC), breaker type (thermal magnetic), mounting (DIN rail), and certifications (CSA, UL508). They are mechanically and electrically interchangeable.

Q: What determines substitution eligibility for these circuit breakers? A: Substitution is valid when current rating, AC/DC voltage ratings, breaker type, mounting type, actuator type, pole count, series designation, and regulatory approvals are identical. All three parts meet these criteria.

Q: Are there any differences in performance or application between 1C30UM, 1B30UM, and 1D30UM? A: No performance or application differences exist. The base product number designation (1C, 1B, 1D) reflects internal manufacturer classification but does not affect electrical or mechanical function.

Q: What is the significance of the "UM" suffix? A: The "UM" suffix indicates bulk packaging. All three parts share this packaging designation.

Q: Are all three parts ROHS3 compliant and certified? A: Yes. All three parts are ROHS3 compliant and carry CSA and UL508 certifications, confirming compliance with environmental and safety standards.
