Circuit breaker 4P, 25kA, TM release (thermal and magnetic regulation) EB2S 250/4SA 250A 4P 004671918

Power switch – reliable circuit protection

This four-pole power switch with a rated current of 250A is a solid solution for securing electrical installations. It provides effective protection against overloads and short circuits, and its high short-circuit breaking capacity (25kA at 400V) guarantees safety even in harsh conditions. Equipped with adjustable thermal and magnetic trip units, it allows for precise adjustment of the operating characteristics to the specifics of the protected circuit.

Design and application

The EB2S 250/4SA switch is designed for permanent mounting. Its construction based on screw connections ensures secure and durable wire connections. The control lever makes operation easier, and the trip indicator allows for quick identification of the device's status. It is ideal for electrical switchboards, providing protection for both installers and end users.

Key features and benefits

• High short-circuit breaking capacity (25kA): Ensures installation safety in the event of serious short circuits, minimizing the risk of damage and fire.
• Adjustable thermal (157.5…250A) and magnetic (787.5…2750A) trip units: Allow precise adjustment of the switch characteristics to the load, preventing unnecessary tripping and ensuring optimal protection. Characteristic C allows it to react more slowly to short current surges, therefore it tolerates starting motors well.
• Four poles: Allow protection of three-phase circuits and the neutral working conductor.
• Protection class IP20: Protection against touching fingers and solid objects with a diameter greater than 12.5 mm – standard protection for devices mounted inside switchboard enclosures.
• Possibility of mounting a motor drive (optional): Facilitates remote control of the switch, which is useful in building or industrial automation systems.
• Trip indicator: Quick visual identification of the switch status – whether it has tripped and why.
• Solid construction: The device made of high-quality materials guarantees long-lasting and reliable operation.

Thanks to these features, the EB2S 250/4SA switch is a reliable solution for a wide range of applications – from industrial installations to commercial and residential buildings.
