2B13UM 13A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 2B13UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 13A at 480V AC and 80V DC. This DIN rail-mounted breaker features a lever actuator and dual-pole configuration, designed for industrial control applications. The part is active in production with full stock availability (1087 units). Equivalent substitute parts are necessary when primary inventory is depleted, when specific approval certifications are required for regional compliance, or when operational requirements necessitate alternative thermal-magnetic characteristics within the same current and voltage ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2B13UM is determined by strict equivalence across the following parameters: current rating (13A), voltage ratings (480V AC / 80V DC), breaker type (thermal magnetic), mounting configuration (DIN rail), pole count (2), and actuator type (lever). All substitute parts listed maintain identical electrical and mechanical specifications. The primary distinction between the main part and substitutes lies in the breaker characteristic designation (B, C, or G channel), which reflects different trip curve profiles. Substitutes 2C13UM and 2G13UM meet all parametric requirements for direct replacement in applications where the specific trip characteristic is interchangeable with the original 2B13UM specification.

Parameter Comparison

Engineering Selection Recommendations

All three parts—2B13UM, 2C13UM, and 2G13UM—are active production items with full regulatory compliance. The 2B13UM and 2C13UM both carry CSA, UL508, and VDE certifications, while the 2G13UM carries CSA and UL508 certifications. Selection between these parts should be based on application-specific trip curve requirements and regional certification mandates. For applications requiring VDE compliance, the 2B13UM or 2C13UM are appropriate selections. All parts are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements. Inventory availability ranges from 654 to 1087 units across the three options.

Frequently Asked Questions (FAQ)

Q: Can 2C13UM and 2G13UM be used interchangeably with 2B13UM? A: Yes, provided the application permits variation in breaker trip characteristics. All three parts share identical current ratings (13A), voltage ratings (480V AC / 80V DC), mounting configuration (DIN rail), pole count (2), and actuator type (lever). The B, C, and G designations indicate different thermal-magnetic trip curves; substitution is valid only when the specific trip characteristic is not a design requirement.

Q: What is the difference between the B, C, and G channel designations? A: The channel designation reflects the breaker's trip curve profile, which determines the response time to overcurrent conditions. These are distinct product variants within the V-EA series, each with specific thermal-magnetic characteristics.

Q: Are all three parts certified for the same applications? A: The 2B13UM and 2C13UM carry identical certifications (CSA, UL508, VDE). The 2G13UM carries CSA and UL508 certifications. Applications requiring VDE certification must use either 2B13UM or 2C13UM.

Q: What is the inventory status for each part? A: 2B13UM has 1087 units in stock, 2C13UM has 654 units, and 2G13UM has 732 units. All are available as new original stock in bulk packaging.

Q: Are these parts RoHS and REACH compliant? A: Yes, all three parts are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.
