SCHURTER 4430.3052 Thermal Circuit Breaker Equivalent & Substitute Parts

Part Overview

The SCHURTER 4430.3052 is an active thermal circuit breaker rated for 20A at 120V AC and 60V DC with rocker panel mount actuation and dual-pole configuration. This component is part of the TA45 series and maintains ROHS3 compliance. Equivalent and substitute parts within this series provide alternative voltage ratings and manufacturing variants while maintaining identical electrical and mechanical specifications for current rating, breaker type, actuator style, and mounting configuration.

Substitute Part Grouping Explanation

Substitution within the SCHURTER TA45 series is determined by matching the following critical parameters:

Current Rating: 20A (fixed across all equivalents)
Breaker Type: Thermal (fixed across all equivalents)
Mounting Type: Panel Mount (fixed across all equivalents)
Actuator Type: Rocker (fixed across all equivalents)
Number of Poles: 2 (fixed across all equivalents)
Series: TA45 (fixed across all equivalents)

The primary variation among substitute parts is the AC voltage rating. The main part 4430.3052 operates at 120V AC, while the majority of substitute parts operate at 240V AC. Both configurations maintain 60V DC rating and identical mechanical form factors. Selection between 120V AC and 240V AC variants depends on the specific circuit voltage requirements of the application.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance. Parts 4430.0572, 4430.1067, and 4430.1068 carry additional regulatory certifications including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. These certifications provide expanded geographic and application scope for installations requiring multi-standard compliance.

Selection between 120V AC (4430.3052) and 240V AC variants (all other listed parts) is determined solely by circuit voltage requirements. The 240V AC rated parts represent the majority of available inventory across the TA45 series, with stock levels ranging from 673 to 1098 units. The 120V AC main part maintains 910 units in stock.

Frequently Asked Questions (FAQ)

Q: Can a 240V AC rated circuit breaker substitute for the 120V AC rated 4430.3052?

A: No. The AC voltage rating is a critical parameter that must match the circuit voltage. Installing a 240V AC rated breaker on a 120V AC circuit will not provide proper protection. Conversely, a 120V AC breaker cannot be used on a 240V AC circuit.

Q: Are all substitute parts mechanically identical to the 4430.3052?

A: Yes. All parts in this substitution group share identical mounting type (panel mount), actuator style (rocker), pole configuration (2-pole), and current rating (20A). The only variation is AC voltage rating.

Q: What is the significance of the additional certifications on parts 4430.0572, 4430.1067, and 4430.1068?

A: These parts carry certifications for CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. These certifications indicate compliance with North American (CSA, UL), European (EN), and international (IEC) standards. Selection of certified variants depends on geographic market requirements and application standards.

Q: Is the 60V DC rating consistent across all substitute parts?

A: Yes. All parts in this group, including the main part 4430.3052, maintain a 60V DC rating. This parameter does not vary among substitutes.

Q: What packaging is available for these parts?

A: All parts are supplied in bulk packaging.
