Power switch 4P, 40kA, TM release (thermal and magnetic regulation) EB2S 250/4HA 250A 4P 004671938

Power switch – reliable protection of electrical installations

This four-pole EB2S 250/4HA power switch is a solid solution for securing circuits with a current of 250A. Designed by ETI Polam, it combines high performance with a durable construction. It is ideal for both industrial installations and public buildings where high reliability and overload resistance are required.

Functionality and application

This switch, thanks to its adjustable thermal and magnetic characteristics, provides optimal protection against the effects of overloads and short circuits. The thermal release (TM) allows precise adjustment to the specifics of the protected circuit, and the high short-circuit breaking capacity (40kA at 400V) guarantees a quick and safe response in emergency situations. The possibility of mounting a motor drive (optional) further increases the functionality of the device, enabling remote control.

Characteristics and benefits

• High short-circuit breaking capacity: 40kA at 400V ensures effective protection of the installation against damage caused by a short circuit.
• Adjustable tripping characteristics: Allows precise adjustment to the load and protection against unwanted shutdowns. The setting range of the overload release is 157.5…250A, and the short-circuit release is 787.5…2750A.
• Solid construction: The permanently mounted device, made of high-quality materials, guarantees long-lasting and trouble-free operation.
• Trip indicator: Facilitates identification of the switch status and location of any problems in the installation.
• Screw connection: Ensures a secure and durable connection of wires.
• Protection class IP20: Protects against accidental contact and the ingress of solid objects larger than 12.5 mm.
• Expandability: Optional motor drive enables remote control of the switch.

The EB2S switch is an investment in the safety and reliability of your electrical installation – both for professionals involved in installation and for end-users expecting long-term protection of their devices.
