2B15UM 15A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 2B15UM is an active thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 15A at 480V AC and 80V DC. This DIN rail-mounted device features a lever actuator and dual-pole configuration, certified by CSA and UL508. Substitute parts are necessary when the primary part is unavailable, when inventory constraints require alternative sourcing, or when application-specific thermal-magnetic characteristics of different channel designations are required within the same electrical specification envelope.

Key Parameters

Substitute Part Grouping Explanation

All substitute parts for the 2B15UM maintain identical electrical and mechanical parameters: 15A current rating, 480V AC and 80V DC voltage ratings, thermal magnetic breaker type, DIN rail mounting, lever actuation, and dual-pole configuration. The substitutes differ only in their channel designation (B, C, D, E, G), which represents internal thermal-magnetic trip curve characteristics specific to each channel variant. All parts share the same series designation (V-EA), approval certifications (CSA, UL508), and compliance status (ROHS3 Compliant, REACH Unaffected). Substitution is valid when the application permits interchangeability of these channel-specific thermal-magnetic characteristics within the specified voltage and current parameters.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts carry identical product status (Active) and hold the same regulatory certifications (CSA, UL508). Selection among 2B15UM, 2C15UM, 2D15UM, 2E15UM, and 2G15UM is determined by application requirements for specific thermal-magnetic trip characteristics associated with each channel designation. All parts maintain ROHS3 compliance and REACH unaffected status. Inventory availability ranges from 680 to 1017 pieces across the substitute group, supporting procurement flexibility.

Frequently Asked Questions (FAQ)

Q: Can 2C15UM, 2D15UM, 2E15UM, and 2G15UM be used interchangeably with 2B15UM?

A: Yes, within applications where the thermal-magnetic trip curve characteristics of the specific channel designation are not a critical design parameter. All parts share identical electrical ratings (15A, 480V AC, 80V DC), mechanical configuration (DIN rail mounting, lever actuation, dual-pole), and regulatory certifications.

Q: What distinguishes the channel designations (B, C, D, E, G) among these parts?

A: Channel designation indicates the internal thermal-magnetic trip curve profile. The provided parameters do not specify the detailed trip curve characteristics for each channel. Selection must be based on application-specific thermal-magnetic requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed (2B15UM, 2C15UM, 2D15UM, 2E15UM, 2G15UM) are ROHS3 compliant and REACH unaffected.

Q: What certifications apply to these circuit breakers?

A: All parts hold CSA and UL508 certifications, meeting North American industrial control standards.

Q: Does packaging differ among substitute parts?

A: All substitute parts are supplied in bulk packaging, consistent with the main part specification.
