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.
This information provides a comprehensive understanding of the Resi9-2P/C63’s performance and applications, ensuring the safe and reliable operation of household or small commercial electrical circuits.
