Residual current circuit breaker, 2P, AC, 63A, 300mA, instantaneous F202 AC-63/0.3 2CSF202001R3630

### Safety and protection of electrical installations

A residual current device (RCD) is a key element of every modern electrical installation, providing protection for people and equipment against electric shock and the effects of short circuits. Model F202 AC-63/0.3, with a rated current of 63A and a sensitivity of 300mA, effectively detects earth leakage currents and instantly disconnects the circuit, minimizing the risk of hazard. This is an instantaneous device, meaning it reacts immediately when a dangerous situation is detected.

Construction and application

This circuit breaker, designed for mounting on a DIN rail, occupies 2 modules in width. Its construction with a lock prevents accidental switching on after switching off as a result of protection operation. It is intended for protecting circuits with a rated voltage of 230V. Thanks to the possibility of connecting wires with a cross-section from 1 to 25 mm², it is compatible with most standard installations. The device is characterized by high resistance to impulse current (0.25 kA) and short-circuit strength at the level of 1 kA, which guarantees its reliable operation even in difficult conditions.

Key features and benefits

• Protection against electric shock: AC sensitivity (alternating current) provides effective protection against dangerous earth leakage currents, protecting users and equipment.
• Fast reaction: Instantaneous tripping time minimizes the duration of the hazard, increasing the level of safety.
• Versatility: Rated current of 63A allows the circuit breaker to be used in various circuits, both in residential and commercial buildings.
• Solid construction: Impulse current resistance of 0.25 kA and short-circuit strength of 1 kA ensure the reliability of the device even in the event of overloads or short circuits.
• Easy installation: DIN rail mounting simplifies and speeds up installation and replacement of the circuit breaker.
• Wide operating temperature range: The ability to operate in a temperature range from -25°C to 55°C makes the device suitable for use in various environmental conditions.
• Compliance with standards: Meets the requirements of IEC EN 61008 standard, which confirms its safety and quality.
• Expandability: Possibility of additional equipment allows adaptation of the circuit breaker to specific installation needs.

Additional information: IP2X protection degree provides basic protection against touching the housing and against the ingress of solid objects larger than 12mm. The rated insulation voltage Ui is 500V and the rated impulse withstand voltage Uimp is 4kV.
