Residual current circuit breaker type G/B 4-pole FRCdM-63/4/03-G/B 167898

Safety and Reliability in Your Electrical Installation

Residual Current Circuit Breaker (RCCB) FRCdM-63/4/03-G/B is a key element ensuring the protection of people and equipment in every electrical installation. This device, manufactured by the renowned Eaton company, effectively protects against electric shock and prevents fires resulting from short circuits and overloads. Designed for both professional installers and end-users, it offers high reliability and easy mounting on a DIN rail.

Functionality and Parameters

The FRCdM-63/4/03-G/B RCCB is a 4-pole device with a rated current of 63A and a B tripping characteristic, meaning it reacts to leakage currents of 0.3A. This ensures effective protection in circuits exposed to the risk of electric shock. Its short-circuit strength of 10 kA guarantees safety even in the event of strong overvoltages. Additionally, the tripping mechanism lock prevents accidental switching on of the breaker after it has tripped.

• Short-circuit protection: The breaker quickly disconnects the circuit in the event of a short circuit, minimizing the risk of equipment damage and fire.
• Shock protection: Reacts to small leakage currents, protecting users from dangerous electric shocks.
• Wide range of applications: Suitable for use in domestic, commercial and industrial installations.
• DIN rail mounting: Allows for quick and easy mounting in a distribution board.
• High quality workmanship: Ensures long-lasting and trouble-free operation of the device.
• IP20 protection rating: Protects against touching with fingers and solid objects larger than 12.5 mm.

Construction and Application

The FRCdM-63/4/03-G/B RCCB is characterized by a compact design with a width of 4 modules, which allows for efficient use of space in the distribution board. It has connection terminals allowing the connection of wires with a cross-section from 1.5 mm² to 35 mm² (solid) and from 1.5 mm² to 16 mm² (stranded). The device is designed to operate in an ambient temperature from -25°C to 40°C and has a rated insulation voltage Ui of 440V and a rated impulse withstand voltage Uimp of 4kV. This allows it to be used in various environmental conditions. Additionally, the breaker has the possibility of expansion with auxiliary contacts, which increases its functionality.
