Circuit breaker DPX3 250 HP EL S1 3P 250 A 36 kA 423203

Three-pole circuit breaker for demanding applications

This DPX3 250 HP EL S1 power circuit breaker is a robust solution for protecting high-load electrical installations. Designed for operation in three-phase systems, it provides reliable protection against overloads and short circuits. Its high short-circuit breaking capacity (36 kA at 400 V) guarantees safety even in the event of sudden current surges.

Characteristics and application

The DPX3 250 HP EL S1 circuit breaker is a device intended for permanent installation. The rated continuous current of 250 A allows it to be used in circuits powering devices with significant power consumption, such as motors, electric heaters or main distribution boards. The setting range of the overload release (100-250 A) allows precise adjustment to the specifics of the protected installation. This ensures that the device does not switch off unnecessarily during short-term overloads, while effectively responding to emergency situations.

Advantages and design features

• High short-circuit breaking capacity: 36 kA at 400 V – ensures effective protection of the installation against the effects of short circuits.
• Wide adjustment range: The ability to adjust the tripping current of the overload (100-250 A) and short-circuit (375-2500 A) releases allows adaptation to specific needs.
• Three-pole design: Provides complete protection in three-phase systems.
• Trip indicator: Facilitates identification of the circuit breaker status and location of potential failures.
• Possibility of mounting a motor drive: Enables remote control of the circuit breaker, which is useful in automatic energy management systems.
• Solid bolt connections: Ensure secure and durable connection of wires.
• Protection degree IP30: Protects against contact and the ingress of solid objects larger than 2.5 mm, which is sufficient for most standard indoor applications.
• Two switchable auxiliary contacts: Expand the functionality of the circuit breaker, allowing connection of additional signaling or control devices.

The DPX3 250 HP EL S1 circuit breaker is a product of a renowned manufacturer – Legrand Polska – guaranteeing high quality workmanship and reliable operation. It is an investment in the safety and durability of the electrical installation.
