Professional three-pole 10A circuit breaker with 50kA breaking capacity, C curve protection, IP20 finger-safe terminals, and DIN rail mounting for reliable electrical circuit protection.
The Legrand DX3 three-pole modular thermal-magnetic circuit breaker (Reference 410160) is a professional-grade electrical protection device designed for control, protection, and isolation of electrical circuits. This advanced circuit breaker features a 50kA breaking capacity at 400V AC, providing superior protection for residential and small commercial applications. With C curve tripping characteristics, it delivers fast response to short-circuit conditions between 5In and 10In, ensuring reliable circuit protection. The device incorporates IP20 finger-safe terminals that comply with IEC/EN 60529 standards, making it safe for installation in accessible locations.
This modular circuit breaker is engineered for DIN rail mounting with a compact 4.5-module width (80.1mm), allowing efficient panel space utilization. The visible breaking mechanism with red/green mechanical indicator provides clear status indication of circuit conditions. Built-in label holder enables convenient circuit identification. The DX3 breaker accepts copper cable connections from either top or bottom, supporting multi-wired conductors from 1.5-35mm² and solid-core conductors up to 50mm². It operates reliably across a wide ambient temperature range of -25°C to +70°C and maintains halogen-free construction for environmental compliance.
The product is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and accessories, offering flexible system expansion. With a rated voltage of 400V AC, insulation voltage of 500V, and impulse withstand voltage of 6kV, this circuit breaker meets stringent international standards including IEC 60947-2. The device demonstrates IK02 impact resistance and includes comprehensive environmental data with a carbon footprint of 5.436 kg CO2 eq during manufacturing. Installation should be performed by qualified electricians in compliance with local electrical codes.
