Residual current circuit breaker, 2P, A, 63A, 30mA, instantaneous F202 A-63/0.03 2CSF202101R1630

Safety and reliability in your installation

The ABB F202 A-63/0.03 residual current circuit breaker (RCCB) is a key element of electrical protection, designed for both home use and more demanding industrial installations. Its task is to protect people from electric shock and to protect the installation from the effects of short circuits to earth and overloads. This device, with a rated current of 63A and a sensitivity of 30mA, provides a quick response to dangerous situations, disconnecting the power supply when a leakage current is detected.

Construction and mounting

The circuit breaker is designed for mounting on a DIN rail, which facilitates its installation and replacement. Compact dimensions (width 2 modules, depth 69 mm) allow for efficient use of space in the distribution board. The solid construction guarantees long-term and trouble-free operation even in difficult environmental conditions (ambient temperature from -25°C to 55°C). The locking mechanism prevents accidental switching on of the circuit breaker after it has been switched off by the protection device.

Characteristics and application

This two-pole residual current circuit breaker type A is characterized by high resistance to electromagnetic interference, which ensures its reliable operation in various environments. It is designed to operate with a rated voltage of 230V and an insulation voltage of 500V. Short-circuit strength at the level of 1kA provides protection of the device in case of a short circuit in the installation. The rated differential current of 0.03A (30mA) is a commonly used value to ensure effective protection of people from electric shock. The cross-section of the connectable solid conductor up to 25mm² allows connection of wires of different thicknesses, adapting to the specifics of the installation. Compliance with IEC EN 61008 confirms its safety and quality of workmanship.
