2B6UM 6A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 2B6UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 6A at 480V AC / 80V DC with lever actuation and DIN rail mounting. This component is classified as Active product status with full compliance to CSA, UL508, and VDE standards. Substitute parts are identified based on identical electrical ratings, mechanical mounting compatibility, and thermal-magnetic trip characteristics within the V-EA series.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2B6UM are qualified based on the following criteria:

Electrical Equivalence: All substitute parts maintain identical current rating (6A), AC voltage rating (480V), and DC voltage rating (80V).

Mechanical Compatibility: All substitutes feature identical mounting type (DIN Rail), actuator type (Lever), and pole configuration (2-pole).

Functional Equivalence: All substitutes employ thermal magnetic trip characteristics within the V-EA series.

Regulatory Compliance: All substitutes maintain ROHS3 compliance and REACH unaffected status.

The primary distinction among substitute parts lies in the trip characteristic designation (B, C, D, E, G), which defines the thermal-magnetic response curve but does not affect the core electrical or mechanical parameters that determine physical and functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts (2C6UM, 2D6UM, 2E6UM, 2G6UM) are functionally equivalent to the 2B6UM based on identical electrical ratings, mechanical mounting specifications, and thermal-magnetic operation within the V-EA series.

Compliance Status: The 2B6UM, 2C6UM, and 2D6UM maintain full CSA, UL508, and VDE certification. The 2E6UM and 2G6UM maintain CSA and UL508 certification. All parts are ROHS3 compliant and REACH unaffected.

Availability: Inventory levels vary across substitute parts, with 2C6UM offering the highest stock position (1067 pcs) and 2G6UM the lowest (651 pcs).

Selection among equivalent parts should be based on application-specific trip characteristic requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 2C6UM, 2D6UM, 2E6UM, or 2G6UM be used as direct replacements for 2B6UM?

A: Yes. All substitute parts share identical electrical ratings (6A, 480V AC, 80V DC), mechanical mounting (DIN Rail, 2-pole, lever actuation), and thermal-magnetic operation. Physical and functional interchangeability is confirmed across all parameters provided.

Q: What is the difference between the B, C, D, E, and G designations?

A: These designations indicate the trip characteristic curve of the thermal-magnetic breaker. The specific curve affects the response time to overcurrent conditions but does not alter the core electrical or mechanical compatibility parameters.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. All parts listed are ROHS3 compliant and REACH unaffected.

Q: Do all substitute parts carry the same certifications?

A: The 2B6UM, 2C6UM, and 2D6UM carry CSA, UL508, and VDE certifications. The 2E6UM and 2G6UM carry CSA and UL508 certifications. Verify certification requirements for your specific application before selection.

Q: What packaging is available for these parts?

A: All parts are supplied in Bulk packaging.
