Type B RCCB DC Residual Current Circuit Breaker 2 Pole 63A 30mA for EV Charger Smart Self‑Reclosing

A compact, reliable circuit breaker designed to protect electrical circuits by interrupting fault currents and preventing damage to wiring and equipment. Suitable for panel installation where dependable overcurrent protection and simple reset capability are required. Key benefits Protects circuits from overloads and short circuits by interrupting current quickly and reliably. Reduces downtime with a resettable design that restores service after a cleared fault without replacing fuses. Minimizes equipment damage and wiring stress by isolating fault conditions before they escalate. Compact footprint saves panel space and simplifies system layout. Straightforward installation and replacement reduce service time and labor. What it does Automatically detects abnormal current and opens the circuit to stop fault current flow. Provides manual on off control for normal operation and maintenance isolation. Designed for repeated operation with consistent trip performance and reliable electrical contact. Compatibility and installation Intended for use in standard electrical distribution panels and switchboards; compatible with common DIN rail and panelmount setups where applicable. Accepts typical conductor sizes via screw or clamp terminals; verify model specifications for recommended torque and conductor cross section. Check the product label or specification sheet for exact rated current, voltage, number of poles, and interrupting capacity before installation. Size and material Low profile, spaceefficient housing suited to tight panel environments. Durable insulating enclosure and conductive internal contacts engineered for long service life under normal operating conditions. Built to integrate with standard terminal and mounting systems used in residential, commercial, and industrial installations. Performance and reliability Designed to provide consistent trip response to overload and short circuit conditions. Robust contact design and mechanism ensure reliable electrical connection and switching over many cycles. Modular design facilitates inspection, replacement, and maintenance without extensive panel modification. Practical use scenarios Building distribution panel: Protect branch circuits feeding lighting, receptacles, and HVAC equipment while allowing quick restoration after a cleared fault. Motor and equipment protection: Serve as a primary protective device for motors and control circuits when matched to the correct current rating and trip characteristics. Renewable and storage systems: Use in inverter output or battery string protection where models are rated for the specific system voltage and fault current requirements. Notes for buyers and installers Select the correct model based on rated current, number of poles, voltage rating, and interrupting capacity for your application. Follow local electrical codes and the product specification sheet during installation and commissioning. Periodic inspection and correct tightening of terminals help maintain reliable electrical performance. Refer to the model specifications supplied with the product for exact technical ratings and compatibility details before and installation.
