Power switch 3P, 25kA, TM EB2 250/3L 250A 3p trip unit 004671073

Power switch – reliable installation protection

This three-pole EB2 250/3L power switch with a rated current of 250A and a short-circuit breaking capacity of 25kA is a solid solution for protecting electrical circuits. Designed for both professional and home use, it provides effective protection against overloads and short circuits. The device's construction allows for mounting on a TH rail, which simplifies installation and integration with existing systems.

Functionality and technical parameters

The switch is characterized by an adjustable setting range for the overload release (157.5…250A) and short-circuit release (1500…2500A), which allows for precise adjustment to the specifics of the protected installation. Thanks to this, the device reacts adequately to the type of threat, minimizing the risk of damage and downtime. The tripping indicator informs about the operation of the protection, making it easier to diagnose problems. The switch has a protection degree of IP20, which provides basic protection against contact and ingress of solid objects. The possibility of using a motor drive expands the functionality of the device, enabling remote control.

• Rated current: 250A – ensures stable operation in typical circuits with high power consumption.
• Short-circuit breaking capacity: 25kA at 400V – guarantees effective disconnection of the circuit in the event of a short circuit, protecting the remaining elements of the installation.
• Release adjustment: The setting range for the overload and short-circuit release allows you to adapt the operating characteristics to the needs of a specific application.
• Mounting: Designed for mounting on a TH rail – a standard solution ensuring quick and easy mounting in electrical switchboards.
• Construction: Fixed device – ensures stability and reliability of connections.
• Connection type: Screw connection – guarantees a secure and durable connection of the power supply cables.
