Residual current circuit breaker type A 2-pole FRCmM-25/2/003-A 170431

Two-pole residual current circuit breaker from the FRCmM series provides reliable protection of electrical installations against the effects of short circuits and electric shock. Model FRCmM-25/2/003-A, with a rated current of 25A and sensitivity A (0.03A), effectively protects people and devices from dangerous leakage currents. It is a key element of every safe electrical installation, both in residential and commercial buildings.

Features and application

This residual current circuit breaker is designed to protect electrical circuits with a rated voltage of 240V and a frequency of 50/60Hz. Its compact width of 2 modules allows for easy mounting on a DIN rail in a distribution box. The mechanical lock prevents accidental disconnection, which increases safety. The rated impulse withstand voltage is 0.25 kA, and the short-circuit withstand capacity (Icw) reaches 10 kA – this guarantees stable operation even in the event of overloads. The possibility of additional equipment allows you to adapt the circuit breaker to specific installation needs.

This circuit breaker is used in circuits with a cross-section of multi-wire conductors from 1.5 to 16 mm² and solid-core conductors from 1.5 to 35 mm². Thanks to type A sensitivity, it effectively reacts to leakage currents generated, for example, due to damage to insulation or failure of electrical devices. It is designed to operate at temperatures from -25°C to 40°C, which makes it suitable for most environmental conditions. The IP20 degree of protection provides protection against finger contact, but does not protect against the effects of water.

Advantages and benefits

• Safety: Provides effective protection against electric shock and equipment damage thanks to high sensitivity and fast reaction to leakage currents.
• Versatility: Suitable for a wide range of applications in AC electrical installations with a voltage of 240V.
• Compactness: A width of 2 modules makes it easy to install even in crowded distribution boards.
• Durability: Made of high-quality materials, resistant to environmental conditions and mechanical damage – this is confirmed by compliance with safety standards (has the CE marking).
• Easy installation: The method of mounting on a DIN rail significantly speeds up installation and replacement of the circuit breaker.
• Mechanical lock: Increases safety by preventing accidental disconnection of the device during operation.
• Interference resistance: The rated impulse withstand voltage is as high as 4 kV, which ensures stable operation even with disturbances in the electrical network.
