Residual current circuit breaker type AC 4-pole FRCmM-63/4/003 170412

Safety and reliability in your electrical installation

The Eaton FRCmM-63/4/003 residual current circuit breaker (RCCB) is a key element ensuring the protection of people and equipment in electrical installations. The device is designed to detect short circuits and earth leakage currents, effectively disconnecting the circuit in case of a hazard. The 4-pole design makes it suitable for protecting three-phase and single-phase circuits with a neutral conductor.

Features and application

This AC type RCCB, with a rated current of 63A and a sensitivity of 0.03A, is ideal for use in residential, commercial and industrial buildings. The use of AC characteristic means that it reacts to alternating currents with a sinusoidal waveform, providing effective protection against electric shock. The mechanical lock prevents accidental disconnection of the device, increasing work safety. The possibility of mounting on a DIN rail facilitates integration with the existing electrical infrastructure.

Parameters and benefits for professionals

The circuit breaker is characterized by a high short-circuit strength of 10 kA, which guarantees its reliable operation even in the event of large overvoltages. A wide range of conductor cross-sections (1.5 - 16 mm² for multi-wire and 1.5 - 35 mm² for single-wire) provides flexibility during installation. The rated impulse withstand voltage of 4 kV further increases the device's resistance to interference. The width of 4 modules allows for efficient use of space in the switchgear cabinet. The ambient temperature in operating conditions from -25 to 75°C enables installation in various environmental conditions. The degree of protection IP20 provides basic protection against contact and ingress of solid objects. Additionally, the possibility of expansion with additional equipment allows the circuit breaker to be adapted to the specific needs of the installation.
