Schneider Electric's Resi9-2P/C63

Schneider Electric's Resi9-2P/C63 is a miniature circuit breaker (MCB) specifically designed for household power distribution. As part of the Resi9 series, it is primarily used to protect electrical circuits from overload and short-circuit faults.

 I. Core Parameters and Functions

1. Basic Specifications  

   Pole Configuration: 2P (simultaneously disconnects live and neutral wires).  

   Rated Current: 63A, suitable for high-power circuits (e.g., air conditioners, kitchen appliances, etc.).  

   Trip Characteristic: Curve C, with an instantaneous trip range of 5-10 times the rated current, ideal for lighting and general household loads.  

   Breaking Capacity: 6kA (complies with IEC 60898-1 standard), capable of safely interrupting short-circuit currents.  

   Rated Voltage: 230/400V AC, supporting single-phase and three-phase systems.  

2. Safety Protection  

   Overload Protection: Triggers tripping via bimetallic strip thermal deformation to prevent wire overheating.  

   Short-Circuit Protection: Electromagnetic trip unit responds rapidly to short-circuit currents with a breaking time of less than 10 milliseconds.  

   Mechanical/Electrical Lifespan: 20,000 mechanical operations and 10,000 electrical operations (for 63A model), ensuring long-term reliability.  

   Visi-Safe Contact Indicator: Green indicator bar clearly shows contact断开 status to avoid misoperation.  

3. Design and Installation  

   Modular Structure: Compatible with standard 35mm DIN rail mounting, and can be combined with Resi9 series residual current accessories (e.g., RCBO).  

   Tunnel-Type Terminal Blocks: Supports 16-35mm² wires, featuring anti-loose connection design and IP20B protection rating.  

   Ergonomic Handle: Large-inclination design for non-slip operation and comfortable grip, suitable for installation in confined spaces.  

 II. Certifications and Compliance

International Standards: Complies with IEC 60898-1 (Household Circuit Breakers) and GB/T 10963.1 (Chinese Standard), certified by CCC.  

Environmental Requirements: Materials meet EU RoHS and REACH directives; packaging contains 70% recycled materials, emphasizing green energy efficiency.  

 III. Application Scenarios

Household Power Distribution: Used as a main incoming circuit breaker or for protecting high-power branch circuits (e.g., kitchens, electric water heaters).  

Small Commercial Premises: Suitable for offices, shops, and other scenarios requiring high electrical safety standards.  

Renewable Energy Systems: Works with inverters and energy storage equipment to protect photovoltaic or wind power generation circuits.  

 IV. Comparison with Similar Products

Compared to other Schneider series (e.g., Easy9, Multi9):  

Resi9: Targets the mid-to-high-end household market, emphasizing pre-installed residual current accessories, sleek design, and environmental sustainability, suitable for users pursuing quality and convenience.  

Easy9: Economical household circuit breaker with lower cost and basic functions.  

Multi9: Industrial-grade product with higher breaking capacity (e.g., 10kA), suitable for complex environments.  

 V. Purchasing Recommendations

1. Confirm Requirements: For residual current protection, select models with RCBO functionality (e.g., R9 RCBO 2P C63A 30mA).  

2. Compatibility: The Resi9 series is compatible with distribution boxes and busbar systems from brands like Hager and Legrand.  

3. Installation Notes: Professional electricians are recommended for installation to ensure secure wiring and compliance with local electrical codes.
