Residual current circuit breaker, 4P, A, 100A, 30mA, short-delay F204 A-100/0.03 AP-R 2CSF204401R1900

Protection of installations and people with ABB F204 A-100/0.03 residual current circuit breaker

This four-pole residual current circuit breaker (RCD) from ABB's F200 series is a key element ensuring safety in every electrical installation. Designed to protect against the effects of short-circuit currents to earth, it protects both people and equipment. Its task is to quickly disconnect the circuit in the event of a dangerous leakage current being detected, minimizing the risk of electric shock.

This circuit breaker, with a rated current of 100A and a sensitivity of 30mA (type A), is perfect for residential, commercial and industrial installations. The A characteristic means that it is particularly effective in detecting leakage currents with frequencies close to those found in electronic devices – making it an ideal choice for modern installations.

#### Construction features and mounting

* **Four-pole design:** allows protection of the entire circuit.

• Width of 4 modules: allows for efficient use of space in the switchgear.

• Mounting on DIN rail: ensures quick and easy installation.

• Locking: prevents accidental switching on of the circuit breaker after it has been switched off by the protection device.

• Short-circuit strength 1kA: ensures reliable operation even in the event of high short-circuit currents.

• Impulse withstand voltage 3kA: increases the safety and durability of the device.

• Wire cross-section: accepts solid wires with a diameter of 35 mm² and stranded wires up to 35 mm², providing flexibility in wire selection.

• Operating temperature: can operate in an ambient temperature from 0°C to 55°C, making it a universal solution for different environmental conditions.

The use of a rated voltage of 400V AC and a rated impulse withstand voltage Uimp of 4kV guarantees reliable operation in standard network conditions. The degree of protection IP2X provides basic protection against contact with solid foreign objects. The rated differential current at 0.03A provides effective protection against electric shock.
