SCHURTER 4430.2849 Circuit Breaker Thermal 20A 240VAC 60VDC Equivalent & Substitute Parts

Part Overview

The SCHURTER 4430.2849 is a thermal circuit breaker rated for 20A at 240V AC and 60V DC, featuring a rocker panel mount actuator with green illumination. This component is classified as Active product status and is designed for applications requiring overcurrent protection in AC and DC circuits. Substitute parts become necessary when the primary part number experiences supply constraints, inventory depletion, or when alternative sourcing from the same manufacturer's product line is required while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 4430.2849 are determined by strict equivalence across the following critical parameters:

• Current Rating: 20A
• Voltage Rating AC: 240V
• Voltage Rating DC: 60V
• Breaker Type: Thermal
• Mounting Type: Panel Mount
• Actuator Type: Rocker
• Number of Poles: 2
• Series: TA45
• Illumination: Green
• Illumination Voltage: 220V (Nominal)
• Approval Agencies: CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077
• RoHS Status: ROHS3 Compliant

All substitute parts listed maintain identical electrical ratings, mechanical configuration, and regulatory compliance certifications. Substitution is valid only when all parameters match exactly.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—4430.2849, 4430.0924, and 4430.2051—are functionally equivalent thermal circuit breakers within the SCHURTER TA45 series. Selection among these alternatives should be based on:

• Inventory availability and lead time requirements
• Supply chain logistics and regional sourcing preferences
• Compliance certification requirements for the target application (all three maintain identical regulatory approvals: CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077)
• RoHS3 compliance status (all three are compliant)
• REACH regulatory status (all three are unaffected)

No technical performance differentiation exists between these part numbers. Direct substitution is permissible in all applications where the 4430.2849 is specified.

Frequently Asked Questions (FAQ)

Q: Can I substitute 4430.0924 or 4430.2051 for 4430.2849 in my circuit design?

A: Yes. All three part numbers are parametrically equivalent across all electrical ratings (20A, 240V AC, 60V DC), mechanical configuration (panel mount, rocker actuator, 2-pole), and regulatory certifications. Direct substitution is valid.

Q: Are there any differences in illumination between these part numbers?

A: No. All three parts feature identical green illumination at 220V nominal voltage.

Q: Do all substitute parts carry the same regulatory approvals?

A: Yes. All three part numbers maintain identical approval certifications: CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077.

Q: What is the difference between these part numbers if they are equivalent?

A: The part numbers represent different manufacturing batches or inventory tracking codes within SCHURTER's product line. No functional or electrical differences exist between them.

Q: Are all three parts RoHS3 compliant?

A: Yes. All three part numbers are ROHS3 compliant and REACH unaffected.

Q: Can I use these parts interchangeably in existing assemblies?

A: Yes. Identical mounting type (panel mount), actuator configuration (rocker), and electrical specifications ensure mechanical and functional interchangeability.
