Schneider Electric EA9B22530CA is a residual current circuit breaker (RCCB) belonging to the Easy 9 series.
Numero di poli: 2P (two-pole), which can control both the live wire and neutral wire simultaneously.
Corrente nominale: 25UN, indicating that the maximum current the switch can carry for long-term stable operation is 25A.
Residual Operating Current: 30mA. When the residual current in the circuit reaches or exceeds 30mA, the switch will trip rapidly to cut off the circuit, providing residual current protection.
Residual Current Protection Type: Type A. This type of RCCB not only provides protection against alternating sinusoidal leakage current, but also against pulsating direct current leakage current.
Residual Current Release Type: Electronic type, which detects leakage current through electronic circuits and controls the operation of the release.
Tensione nominale: 230VAC, suitable for AC circuits with a rated voltage of 230V.
Packaging Specifications: Usually 6 pieces per box, 48 pieces per carton.
Price: The price varies across different platforms. ForWhatsapp：0086-13811255435, the market price on Cloud Electric Mall is 139.99 CNY per piece.
Scenari applicativi: Suitable for industrial and commercial premises. It can be surface-mounted or hinge-mounted, operates within a temperature range of -40°C to +80°C, and has an IP66 protection rating, making it applicable to harsh environments.
Compared with equivalent products from Siemens (such as models 5SV53120 and 5SV43120), the core advantages of Schneider Electric EA9B22530CA (a 2P, 25UN, 30mA, Type A RCCB in the Easy 9 series) lie in broader protection coverage, stronger environmental adaptability, higher breaking capacity, more compact design, and more flexible installation.
- Comparison of Core Parameters and Protection Performance
| Parameter Item | Schneider Electric EA9B22530CA | Siemens Equivalent Products (5SV53120/5SV43120) | Schneider’s Advantages |
| Protection Type | Type A (protects against AC sinusoidal and pulsating DC leakage current) | Mostly Type AC (only protects against AC sinusoidal leakage current) | Type A offers comprehensive protection, suitable for modern circuits with electronic devices |
| Capacità di interruzione | 6000UN, Im=500A | Generally 4500-6000A | Higher breaking capacity ensures more reliable performance during severe short-circuit faults |
| Tensione nominale | 230VAC, compatible with 240/400V | 230VAC | Wider voltage compatibility, suitable for various power distribution systems |
| Tripping Time | Instantaneous type, ≤0.02s | Instantaneous type, ≤0.02s | Comparable, both meet safety standards |
- Advantages in Environmental Adaptability
- Operating Temperature Range: -40°C to +80°C, far exceeding that of equivalent Siemens products (typically -25°C to +70°C), ensuring more stable and reliable operation in extremely cold or high-temperature environments.
- Protection Rating: IP66. Most equivalent Siemens products have IP20/IP30 ratings. Schneider’s product can be used in outdoor, humid, and dusty harsh environments, with stronger water and dust resistance.
- Anti-interference Performance: It has transient overvoltage resistance and can prevent mal-tripping caused by lightning strikes, misoperations, ecc. Although Siemens products also feature anti-interference design, Schneider’s product performs better in complex industrial electromagnetic environments.
III. Advantages in Structural Design and Installation
- Dimensions and Compatibility: With a width of only 36mm, it supports standard DIN rail mounting, is more compact than some Siemens products, and saves distribution box space.
- Mounting Method: Supports surface mounting or hinge mounting, flexibly adapting to different installation scenarios. Siemens products mostly adopt a single DIN rail mounting method.
- Wiring Convenience: Compatible with wires up to 16mm². The reasonable design of wiring terminals enables faster installation and easier maintenance.
- Neutral/Live Wire Identification: The neutral wire is located on the left side, which conforms to the operating habits of most electricians in China (the neutral wire of Siemens products is mostly on the right side), reducing the risk of installation errors.
- Other Differentiated Advantages
- Current-limiting Feature: Built-in current-limiting design reduces the impact of faults on the system and equipment, and extends electrical service life.
- Integrated Design: The independent and complete residual current protection function can be seamlessly combined with EA9 series circuit breakers to form a comprehensive protection solution.
- Packaging Specifications: 6 pieces per box, 48 pieces per carton, suitable for bulk purchasing, reducing procurement and inventory costs.
- Price Competitiveness: The market reference price is approximately 96-139 CNY per piece. The price on some channels is lower than that of equivalent Siemens products, delivering higher cost-effectiveness.
- Comparison of Application Scenarios
| Scenario applicativo | Schneider Electric EA9B22530CA | Siemens Equivalent Products |
| Industrial Environments | Better (IP66 protection + wide temperature adaptability) | Good (suitable for conventional industrial environments) |
| Commercial Buildings | Excellent (compact design + comprehensive protection) | Excellent (high stability) |
| Residential Premises | Good (safe, reliable, and easy to install) | Good (high brand recognition) |
| Outdoor/Humid Premises | Significant advantage(IP66 waterproof and dustproof) | Not applicable (low IP rating) |
| Circuits with Electronic Devices | Significant advantage(Type A protection) | Requires special models (Type AC is not applicable) |
Compared with equivalent Siemens products, the core value of Schneider Electric EA9B22530CA lies in comprehensive Type A protection coverage, strong adaptability to extreme environments, high breaking capacity, e installazione flessibile, while also offering better price competitiveness and practicality. It is particularly suitable for industrial and commercial projects with high protection requirements and complex environmental conditions, as well as modern electrical systems that need to address diverse leakage current risks.
