Motor starter switch 3-pole Z-MS-25/3 248413

Motor starter – reliable protection for your devices

This three-pole motor starter Z-MS-25/3 from Eaton is a key element in protecting electrical installations, especially for motors. It provides effective protection against overload and short circuit, and also allows for manual control of the motor. Its compact dimensions (54 mm wide, 75 mm high and 80 mm deep) allow for easy mounting in standard distribution boards.

This starter is designed to operate in circuits with a voltage of 400 V and allows for the protection of motors with a power of up to 11 kW. The adjustable setting range of the overload release (16-25 A) and short-circuit release (250-325 A) allows for precise adjustment to the load characteristics. Thanks to this, both the installer and the end user can be sure that the circuit is properly protected.

Functionality and construction

The Z-MS-25/3 starter is characterized by a solid construction and high quality workmanship. Screw connection of the main contacts ensures a secure and durable connection of the wires. The lever actuator facilitates operation of the device, and the lack of an integrated auxiliary contact or undervoltage release simplifies the construction and reduces the cost. The degree of protection IP20 means that the device is protected against finger contact, which increases safety.

It is worth noting the built-in thermal protection, which protects the motor from overheating. The lack of phase failure sensitivity means that the starter does not react to voltage asymmetry, which may be important in some applications. The rated short-circuit breaking capacity at 10 kA at 400 V ensures effective interruption of the circuit in the event of a short circuit. The device is built as a complete unit in a housing, ready for mounting on a DIN rail (EN 50022).
