Circuit breaker DPX3 250 HP EL S1 3P 250 A 100 kA 423253

Three-pole circuit breaker DPX3 250 HP EL S1 – reliable installation protection

This power circuit breaker from Legrand's DPX3 series, with a rated current of 250A, is a solid solution for securing electrical circuits. Designed for use in both industry and commercial buildings, it provides effective protection against overloads and short circuits. The device's design allows for a quick response in the event of a failure, minimizing the risk of damage and downtime.

Characteristics and application

The DPX3 250 HP EL S1 circuit breaker is characterized by a high short-circuit breaking capacity – up to 100 kA at 400V, which guarantees safety even in difficult working conditions. Thanks to the adjustable range of the overload release (100-250A) and short-circuit release (375-2500A), it can be precisely adapted to the specifics of the protected installation. Designed for busbar mounting, it offers flexibility in switchboard configuration. It has two switchable auxiliary contacts, which facilitates integration with control and signaling systems.

• Solid construction: The device is made of high-quality materials, which ensures its durability and reliability.
• Wide voltage range: The possibility of use in installations with a rated voltage from 230V to 690V increases its versatility.
• High short-circuit breaking capacity: 100 kA at 400V guarantees effective protection against the effects of short circuits.
• Parameter adjustment: The ability to adjust the setting range of the releases allows for optimal protection for a specific application.
• Trip indicator: Allows for quick identification of the circuit breaker status and causes of failure.
• Possibility of motor drive mounting: Optional motor drive facilitates remote control of the circuit breaker.

Construction and mounting

The DPX3 circuit breaker has bolted connections, ensuring a secure and durable connection of the conductors. Its compact dimensions and the possibility of busbar mounting make installation easy even in tight spaces. The IP30 protection degree protects against contact and the ingress of solid objects larger than 2.5 mm. It is equipped with a lever for manual switching on/off and a contact status indicator. This makes diagnostics and operation of the device simple and intuitive for both the installer and the end user.
