3C6UM 6A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 3C6UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 6A at 480V AC and 80V DC. This DIN rail-mounted breaker features a lever actuator and three poles, designed for industrial electrical distribution and protection applications. The part is currently active in production with full inventory availability. Equivalent substitute parts are necessary when the primary part is unavailable, when managing multi-source supply chains, or when application-specific thermal characteristics require alternative trip curve selections within the same electrical ratings.

Substitute Part Grouping Explanation

All substitute parts for the 3C6UM maintain identical electrical and mechanical specifications: 6A current rating, 480V AC / 80V DC voltage ratings, thermal magnetic operation, three-pole configuration, lever actuation, and DIN rail mounting. The substitutes differ only in their thermal trip curve characteristic, designated by the letter prefix (B, C, D, E, G). These curve designations define the time-current response of the breaker but do not alter the fundamental electrical compatibility or physical form factor. All substitute parts are manufactured by Altech Corporation within the V-EA series and carry equivalent regulatory approvals and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

All five part numbers are active products with current manufacturing status and full regulatory compliance. The 3C6UM, 3B6UM, and 3D6UM carry CSA, UL508, and VDE approvals, while 3E6UM and 3G6UM carry CSA and UL508 approvals. Selection between these interchangeable parts should be based on application-specific thermal curve requirements and regulatory jurisdiction requirements. The 3D6UM offers the highest current inventory level at 1120 pieces, followed by 3G6UM at 1025 pieces. All parts are ROHS3 compliant and carry identical electrical ratings and mechanical form factors.

Frequently Asked Questions (FAQ)

Q: Are all substitute parts electrically interchangeable with the 3C6UM? A: Yes. All substitute parts maintain identical current ratings (6A), voltage ratings (480V AC / 80V DC), pole configuration (3), mounting type (DIN rail), and actuator type (lever). They differ only in thermal trip curve characteristic.

Q: What is the difference between the B, C, D, E, and G designations? A: These letters designate the thermal trip curve of the breaker, which defines the time-current response during overload conditions. The curve selection depends on the specific application and load characteristics, but all curves are compatible with the same electrical system parameters.

Q: Do all substitute parts have the same regulatory approvals? A: The 3C6UM, 3B6UM, and 3D6UM carry CSA, UL508, and VDE approvals. The 3E6UM and 3G6UM carry CSA and UL508 approvals. Verify that the selected part meets the regulatory requirements for your specific jurisdiction and application.

Q: Can I use these parts interchangeably in existing installations? A: Physical and electrical interchangeability is confirmed. However, thermal curve differences may affect circuit protection characteristics. Ensure the selected curve is appropriate for the connected load and system protection scheme.

Q: What packaging is used for these parts? A: All parts are supplied in bulk packaging.

Q: Are these parts RoHS compliant? A: Yes, all parts are ROHS3 compliant and REACH unaffected.
