Circuit breaker DPX3 250 HP EL S1+RCD 4P 160 A 36 kA 423217

Protection and reliability in your electrical installation

The DPX3 250 HP EL S1+RCD circuit breaker is an advanced solution for protecting electrical circuits, combining the functions of an overcurrent and residual current device. Designed to operate in systems with a rated voltage from 230 to 690 V, it provides comprehensive protection against overloads, short circuits and electric shock. A rated continuous current of 160 A and a high short-circuit breaking capacity (36 kA at 400 V) guarantee stable operation even in demanding conditions.

Design and application

The DPX3 250 HP EL S1+RCD circuit breaker is a fixed-mounted device with four poles. Its design allows for easy connection of wires using bolted connections. The integrated residual current protection with adjustable rated current (0.03 - 0.3 - 1 - 3 A) and time delay (0 - 0.3 - 1 - 3s) increases the safety of use. This makes the device ideal for both domestic and industrial installations where high reliability and personal protection are required.

Advantages and benefits

• Comprehensive protection: combining the functions of an overcurrent and residual current device in one device minimizes the risk of failure and ensures safety.
• High short-circuit breaking capacity: 36 kA at 400 V guarantees effective protection of the installation against the effects of sudden overvoltages.
• Parameter adjustment: the ability to adjust the residual current rated current and time delay allows the device to be adapted to the specific needs of the installation.
• Tripping indicator: informs about the operation of the circuit breaker, making it easier to locate the problem.
• Expandability: an optional motor drive allows for remote control of the circuit breaker. The availability of two switchable auxiliary contacts expands the functionality of the device to integrate with automation systems.
• Overload release setting range: from 64 to 160 A allows precise matching to the installation load.
• Solid construction: the device made of high-quality materials ensures durability and reliable operation for a long time. Protection class IP30 protects against contact and access to hazardous live parts.
