The product is designed to operate within a temperature range of -25°C to +55°C, making it suitable for a wide variety of installation conditions. As part of the Schneider Electric EZ9 series, the EZ9R56463 is recognized for its ease of use and integration with other modular devices such as MCBs and surge protectors. It is an excellent choice for protecting circuits in industrial automation panels, commercial buildings, and residential distribution boards. The device is certified with CE, CCC, and other international marks, ensuring compliance with global electrical safety regulations. Schneider Electric's commitment to quality and innovation is evident in this RCCB, which offers both performance and peace of mind for electrical professionals. The Schneider Electric EZ9R56463 is a high-performance residual current circuit breaker (RCCB) from the EZ9 series, designed for reliable protection against earth leakage currents in residential and commercial electrical installations. Basic Product Information AC type residual current detection for sinusoidal AC currents Rated voltage 400V AC, 50/60Hz, insulation voltage 500V Breaking capacity 6000A (IEC 61008-1) Compact modular design (4 modules) for DIN rail mounting Trip indicator and test button for safety and maintenance Compliant with IEC 61008-1, GB 16917.1, CE, CCC certifications 4-pole RCCB with 63A rated current and 30mA sensitivity Technical Specifications Version & Model Difference The EZ9R56463 is part of the Schneider Electric EZ9 series, which includes various RCCBs with different pole configurations (2P, 4P), rated currents (16A to 63A), and sensitivities (30mA, 100mA, 300mA). Compared to other models in the series, the EZ9R56463 is specifically a 4-pole, 63A, 30mA AC type device. It differs from the EZ9R56440 (40A) and EZ9R56425 (25A) in rated current, and from the EZ9R56463 (AC type) to the EZ9R56463 (A type) in residual current detection type. The '63' in the model number indicates the rated current, while the '30' in the sensitivity is not directly in the model but is a key specification. This model is designed for three-phase systems requiring high current protection with sensitive earth leakage detection. Application Scenarios Can the EZ9R56463 be used in a single-phase system? The EZ9R56463 is a 4-pole device rated for 400V AC three-phase systems. While it can be used in single-phase systems by connecting only one phase, it is not the most economical choice. For single-phase applications, Schneider Electric offers 2-pole RCCBs like the EZ9R56263 (63A, 30mA, 2P). Always ensure the device's rated voltage and current match your system requirements. What is the breaking capacity of the EZ9R56463? The EZ9R56463 has a rated breaking capacity (Icn) of 6000A according to IEC 61008-1. This means it can safely interrupt a short-circuit current up to 6000A without damage. This is suitable for most residential and commercial installations where the prospective short-circuit current is below this value. Does the EZ9R56463 require regular testing? Yes, it is recommended to test the RCCB periodically (typically every month) by pressing the 'T' (test) button. This ensures that the tripping mechanism operates correctly. The test button simulates a residual current and should cause the device to trip. If it does not trip, the device may be faulty and should be inspected by a qualified electrician. What is the difference between AC type and A type RCCBs? AC type RCCBs (like the EZ9R56463) are designed to detect sinusoidal alternating residual currents. A type RCCBs also detect pulsating DC residual currents, which may be present in equipment with electronic components. For most residential and commercial applications with standard AC loads, AC type is sufficient. However, if your installation includes devices like variable speed drives or chargers, an A type RCCB is recommended.
