Power circuit breaker with electronic trip unit with measurement functions DPX3 250 EL+P 4P 100A 25kA 420415

Power circuit breaker with electronic release – reliable protection and precision

The DPX3 250 EL+P circuit breaker is an advanced solution for protecting electrical installations. A four-pole circuit breaker with a rated current of 100A and a short-circuit breaking capacity of 25kA, designed to protect circuits against overloads and short circuits. Equipped with an electronic release, it offers precise and fast response to disturbances, minimizing the risk of damage and downtime.

Functionality and application

This model features a built-in undervoltage release, which provides additional protection for the installation against voltage drops. The electronic release allows for accurate setting of the tripping threshold, which is particularly important in applications requiring high selectivity. This circuit breaker is used in commercial buildings, industrial facilities, and residential installations with increased safety requirements. TH rail mounting ensures easy installation and integration with existing systems.

Advantages for professionals and end users

• Precise protection: Electronic release ensures accurate operation and minimizes the risk of false alarms.
• High short-circuit breaking capacity: 25kA guarantees effective disconnection of the circuit in the event of serious short circuits.
• Undervoltage release: Additional layer of protection against voltage drops, protecting sensitive devices.
• Easy installation: Design adapted for TH rail mounting simplifies and speeds up installation.
• Status indication: Trip indicator informs about the operation of the circuit breaker, facilitating problem diagnosis.
• Expandability: Optional motor drive enables remote control of the circuit breaker.
• Solid connections: Screw connections ensure secure and durable connection of wires.
• Voltage universality: Designed to operate in networks with a voltage of 220 to 690V, which increases its flexibility of application.

The IP30 degree of protection provides protection against touching fingers and against the ingress of solid objects larger than 2.5 mm, which is sufficient for most standard indoor installations. The rated continuous current of 100A allows for safe loading of the circuit without the risk of overheating the device. The adjustment range of the overload release (40-100A) allows you to adapt the operating characteristics to the specifics of the protected circuit.
