Power switch 3P, 25kA, TM release (thermal adjustment) EB2S 160/3SA 125A 3P 004671904

Power switch – reliable installation protection

This three-pole power switch with a rated current of 125A is a solid solution for securing electrical circuits. Designed for demanding applications, it provides effective protection against overloads and short circuits. Its construction, based on an adjustable thermal release, allows for precise adjustment to the load characteristics.

Characteristics and application

The EB2S 160/3SA switch is characterized by a high short-circuit breaking capacity – up to 25kA at 400V, making it an ideal choice for industrial and commercial installations. The adjustable overload release setting range (78.8…125A) allows adaptation to the specific needs of a given circuit, minimizing the risk of unnecessary tripping during short-term load surges. This makes the device perform well when starting motors that generate high inrush currents. The switch is permanently mounted and intended for use in installations with a voltage of up to 690V AC and 250V DC.

Advantages and design features

• High short-circuit breaking capacity (25kA): ensures installation safety in the event of serious disturbances.
• Adjustable thermal release: allows precise adjustment to the load characteristics and minimizes the risk of false tripping.
• Three-pole construction: ideal for protecting three-phase electrical circuits.
• Tripping indicator: facilitates identification of the switch status and quick location of the problem in the event of a failure.
• Screw connection of main contacts: guarantees a secure and durable connection of the wires.
• Protection degree IP20: provides protection against touching and against the ingress of solid objects larger than 12.5 mm.
• Solid construction of a permanently mounted device: ensures stability and reliable operation for a long time.
• Lever actuator: enables intuitive operation of the device.

The device does not have a built-in or optional motor drive or an integrated short-circuit protection to earth, making it a classic solution for a wide range of applications. Its design has been designed for easy installation and maintenance by professional installers, but is also understandable for end-users looking for reliable protection of their electrical installations.
