3 Pole 125A Residual Current Circuit Breaker RCBO 30mA DIN Rail Mounted with Thermal Magnetic Protection

Compact circuit breaker designed to protect electrical circuits from overloads and short circuits while minimizing downtime and panel space. Key benefits Clear protection: thermal and magnetic trip action detects overloads and short circuits, reducing risk of circuit damage and component failure. Flexible compatibility: available in single pole and multi pole configurations and a range of current ratings to match residential, commercial, and light industrial systems. Space efficient: compact footprint fits standard distribution boards and DIN rail enclosures, allowing denser layout without compromising accessibility. Durable construction: robust thermoset housing and corrosion resistant contact materials provide reliable operation in typical electrical environments. Simple operation and maintenance: manual toggle for easy reset and clear trip indication for quick troubleshooting. What it does and why you need it Interrupts current when levels exceed the selected rating to protect wiring and downstream devices. Combines thermal response for gradual overloads and magnetic response for abrupt faults, giving balanced protection across common fault types. Lets you select the appropriate pole count and current rating for individual circuits, improving system reliability and making maintenance safer and faster. Key attributes Function: thermal and magnetic circuit interruption with manual reset. Compatibility: designed for use in standard electrical panels, control cabinets, motor starters, inverter systems, and power distribution blocks. Compatible with common wiring practices and terminal types. Size: compact modular form factor suitable for DIN rail mounting or panel mounting versions; multiple pole widths available to fit standard enclosures. Material: flame retardant thermoset housing with copper alloy contacts and wear resistant contact surfaces for consistent electrical performance. Performance: available breaking capacities and current ratings to suit lighting circuits, motor feeds, auxiliary circuits, and control circuits. Stable trip characteristics across expected temperature ranges. Typical applications Residential distribution board: protect lighting, receptacle, and small appliance circuits with a compact breaker that fits common panel spaces. Industrial control panel: isolate and protect motor control circuits, solenoids, and machine control components while simplifying service procedures. Mobile and off grid systems: protect inverter outputs, battery feeder circuits, and onboard distribution in marine, RV, and renewable installations where space and reliability matter. Installation and selection guidance Choose the correct current rating and pole count for the circuit and load type. Confirm trip curve and breaking capacity meet the application requirements. Verify mounting style and terminal orientation for your panel or enclosure. Tighten terminals to specified torque and follow standard wiring practices. Use coordinated upstream and downstream protection where required to achieve selective tripping and minimize system downtime. Reliable, easy to install protection for a wide range of electrical circuits. Select the model and rating that match your system to ensure consistent performance and straightforward maintenance.
