2C4UM Thermal Magnetic Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 2C4UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, part of the V-EA series. This DIN rail-mounted breaker is designed for 4A applications at 480V AC / 80V DC with lever actuation and 2-pole configuration. The product is active and widely stocked, with 1080 units available. Equivalent substitute parts are necessary when primary inventory is depleted, when specific thermal characteristics (C, D, E, G, or Z curve ratings) are required for application-specific protection profiles, or when alternative sourcing is needed while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

All substitute parts for the 2C4UM maintain identical electrical and mechanical parameters: 4A current rating, 480V AC / 80V DC voltage ratings, thermal magnetic protection type, 2-pole lever-actuated configuration, and DIN rail mounting. The substitutes differ only in their thermal trip curve characteristic, designated by the letter designation in the part number (C, D, E, G, or Z). These curve ratings define the thermal response time and trip threshold behavior under overload conditions. All substitute parts are manufactured by Altech Corporation within the V-EA series and share the same base product architecture. Substitution is valid when the application permits interchangeability of thermal curve characteristics or when a specific curve rating is required for circuit protection coordination.

Engineering Selection Recommendations

All five part numbers (2C4UM, 2D4UM, 2E4UM, 2G4UM, 2Z4UM) are active products with full regulatory compliance. The 2C4UM, 2D4UM, and 2E4UM carry CSA, UL508, and VDE approvals. The 2G4UM and 2Z4UM carry CSA and UL508 approvals. Selection between these interchangeable parts depends on the required thermal trip curve characteristic for the specific circuit protection application. All parts are ROHS3 compliant and REACH unaffected. Inventory levels are adequate across all variants, with 2D4UM showing the highest stock position at 1169 units.

Frequently Asked Questions (FAQ)

Q: Can 2D4UM, 2E4UM, 2G4UM, and 2Z4UM be used interchangeably with 2C4UM?

A: Yes, these parts are parametric equivalents with identical electrical ratings (4A, 480V AC / 80V DC), mechanical configuration (2-pole, lever-actuated, DIN rail mount), and breaker type (thermal magnetic). The only difference is the thermal trip curve characteristic. Interchangeability is valid when the application does not require a specific curve rating.

Q: What determines the choice between C, D, E, G, and Z curve ratings?

A: The thermal curve designation defines the overload trip response time and threshold. Selection is determined by the circuit protection coordination requirements and the specific application's inrush current characteristics. Consult application-specific protection coordination studies to determine the appropriate curve.

Q: Are all substitute parts manufactured by the same company?

A: Yes, all five parts are manufactured by Altech Corporation and belong to the V-EA series, ensuring consistent design architecture and performance characteristics.

Q: What are the regulatory compliance differences between the substitute parts?

A: The 2C4UM, 2D4UM, and 2E4UM carry CSA, UL508, and VDE approvals. The 2G4UM and 2Z4UM carry CSA and UL508 approvals. All parts are ROHS3 compliant and REACH unaffected.

Q: Is there a preferred part number for general applications?

A: Selection should be based on the required thermal curve characteristic for your specific circuit protection application. All parts maintain identical electrical and mechanical specifications, so the choice depends on protection coordination requirements rather than general preference.
