Power switch 3P, 25kA, TM release (thermal and magnetic regulation) EB2S 250/3SA 250A 3P 004671908

Power circuit breaker EB2S 250/3SA is a three-pole device designed to protect electrical installations against overloads and short circuits. The rated continuous current of 250A makes it an ideal solution for both industrial installations and public buildings. The construction with a thermal-magnetic (TM) trip unit provides effective and precise protection, reacting to various types of disturbances.

Characteristics and application

This circuit breaker is part of the EB2S series, characterized by high reliability and durability. The short-circuit breaking capacity of 25kA at 400V, 50Hz guarantees the safety of the installation in the event of a serious failure. Thanks to the adjustable overload (157.5…250A) and short-circuit (787.5…2750A) trip settings, the device can be adapted to the specific requirements of the protected installation. This circuit breaker is used to protect circuits powering various types of loads, such as motors, transformers, and switchboards.

Construction and mounting

The EB2S 250/3SA circuit breaker has screw connections, ensuring a secure and durable connection with the wires. Thanks to the lever-operated design of the actuating element, the device is intuitive and convenient to operate. The trip indicator allows for quick identification of the device status – whether it has tripped due to an overload or short circuit. The device is designed for permanent mounting, ensuring stability and safety of operation. The IP20 degree of protection means that the circuit breaker is protected against finger contact and against the ingress of solid objects larger than 12.5 mm – standard protection for devices mounted in enclosures.

• Adjustment: The ability to precisely adjust the trip settings allows for optimal adaptation to the load characteristics and ensures selective protection of the installation.
• Protection: High short-circuit breaking capacity (25kA) minimizes the risk of damage to the installation in the event of a serious failure.
• Indicator: The presence of a trip indicator facilitates troubleshooting and quick fault location.
• Mounting: Screw connections ensure a solid and reliable connection with the power supply cables.
• Versatility: Optional mounting of a motor drive expands the functionality of the device, enabling remote control.
• Standards: Compliance with standard 60947 confirms that it meets stringent safety and quality requirements.
