Circuit breaker RX3 ВА 3Ф С 63A 4,5KA LEGRAND

Powerful protection for three-phase networks: Legrand RX3 circuit breaker (3P, C 63A, 4.5kA) For ensuring the safety of power lines and industrial equipment, the three-pole Legrand RX3 series circuit breaker is a benchmark of reliability. It is designed to open all three phases simultaneously when an overload or short circuit is detected, which is critically important for protecting three-phase motors and complex electrical installations. Technical characteristics The RX3 3P 63A model has the parameters required for operation in high-power distribution networks: Number of poles (3P): Designed for operation in 380–400 V three-phase networks. Provides simultaneous switching of the three phase conductors. Rated current (63 A): A high rating able to carry a load of up to 41.5 kW (with three-phase connection), which is suitable for incoming distribution boards or high-power equipment. Tripping characteristic (C): Medium tripping threshold of the electromagnetic release, optimal for networks with mixed loads. Breaking capacity (4.5 kA): Guarantees interruption of the circuit when short-circuit currents occur, in line with residential and civil construction standards. Endurance: A high number of mechanical and electrical switching cycles, typical of the Legrand professional series. Advantages of Legrand RX3 three-phase circuit breakers Legrand equipment is valued for the careful design of every detail: Protection against indirect contact: The housing design minimizes the risk of touching live parts. Reliable terminals: Screw terminals provide a stable clamping force, preventing the contact from loosening over time and reducing the risk of heating. European quality: The RX3 series combines Legrand's advanced engineering with the cost-effectiveness required for the mass-market segment. Compatibility: The standard size allows the breaker to be installed in any DIN-rail distribution board alongside other modular devices. Fields of application The Legrand 3P 63A circuit breaker is a key element for the following tasks: Incoming device: Use as the main switch in the distribution boards of private houses, cottages and workshops with a three-phase supply. Industrial equipment: Protection of powerful electric motors, pumping stations and machine tools. Climate control systems: Supply of central air-conditioning systems and powerful electric heating boilers. Installation recommendations Important: When installing a breaker rated at 63A, a copper cable with a cross-section of at least 10–16 mm² must be used. The three-pole version requires accurate balancing of the load across the phases. Check the tightness of the terminals regularly (once a year) to avoid contact resistance. Installation must be carried out by qualified personnel in compliance with all ПУЭ requirements.
