Residual current circuit breaker type G/B+ 4-pole FRCdM-40/4/003-G/B+ 167881

Residual Current Circuit Breaker FRCdM-40/4/003-G/B+ is a reliable protection for electrical installations, designed for both home and commercial use. The device effectively protects against electric shock and the effects of short circuits and overloads. The four-pole design allows it to be used in three-phase circuits.

This model, with a rated current of 40A and B+ sensitivity, provides a quick response to leakage currents, minimizing the risk of danger to people and equipment. The B+ characteristic means that the circuit breaker reacts quickly to current increases, but is less sensitive to short-term surges, which is particularly important when connecting devices with electric motors – such as pumps or compressors. The rated differential current of 0.03A guarantees high protection efficiency.

The circuit breaker's design has been carefully considered for easy mounting on a DIN rail (4 module width). Solid construction with high-quality materials ensures long-lasting and trouble-free operation in a wide range of ambient temperatures (-25°C to +60°C). Additionally, the mechanical lock prevents accidental switching on or off of the device during maintenance or repair. The short-circuit strength of 10 kA demonstrates its resistance to extreme working conditions.

• Versatile application: ideal for protecting lighting circuits, socket outlets and electrical appliances in residential and commercial buildings.
• High efficiency: B+ sensitivity and 0.03A differential current ensure quick and reliable protection against electric shock.
• Easy installation: DIN rail mounting design simplifies installation and servicing.
• Durable construction: resistance to weather and mechanical conditions guarantees long device life.
• Safety: mechanical lock prevents accidental changes to settings.
• Compliance with standards: has a CE marking confirming compliance with European safety standards.

This circuit breaker is also characterized by high surge current resistance (3kA) and rated voltage of 415V and rated impulse withstand voltage Uimp 4kV, making it a reliable element of any electrical installation. The IP20 degree of protection provides protection against finger contact, and the possibility of additional equipment allows you to adapt the functionality to individual user needs.
