RCD adapter DPX3 250 TH35 421074

Residual Current Circuit Breaker – Reliable Installation Protection

This DPX3 250 TH35 power switch is a key element of every safe and efficient electrical installation. Designed by Legrand, it combines the functions of an overcurrent and residual current circuit breaker, providing comprehensive protection against overloads, short circuits, and electric shock. This solution is ideal for both demanding industrial installations and advanced systems in residential buildings.

Design and application

The DPX3 250 circuit breaker is designed for mounting on a TH35 rail, making it easy to integrate with existing distribution boards. Its solid construction guarantees long-lasting and trouble-free operation even in difficult conditions. The rated continuous current of 250A and high short-circuit breaking capacity (25kA at 400V) make it suitable for protecting circuits with high power consumption. The built-in residual current module further increases the level of safety by detecting earth leakage currents and immediately disconnecting the power.

Advantages and benefits

• Comprehensive protection: Combination of overcurrent and residual current functions in one device – saving space and costs.
• High reliability: Legrand products are known for their high quality workmanship and durability, which translates into a long service life.
• Easy installation: Standard TH35 rail mounting ensures quick and easy installation.
• Wide range of applications: Suitable for protecting circuits in residential, commercial and industrial buildings.
• Safety of use: Provides effective protection against electric shock and damage to the installation caused by short circuits and overloads.
• Precise settings: The ability to adjust the overload release settings allows you to adapt the circuit breaker's operating characteristics to the specific needs of the installation.

Additional information for professionals

The DPX3 250 circuit breaker has screw connections, which ensures a secure and durable connection of the wires. The tripping indicator makes it easy to identify the status of the device after the protection has operated. Thanks to the wide range of rated voltage (220-690V), the circuit breaker can be used in various power systems. Compliance with safety standards guarantees proper operation of the device and minimizes the risk of failure.
