Motor starter switch 3-pole Z-MS-0,40/3 248404

Motor starter – reliable protection for motors and installations

This three-pole motor starter from the Z-MS series is a key element in protecting electric motors from overload and short circuit. Designed to operate in installations with a voltage of 400 V, it offers effective protection for both the motor itself and the entire electrical installation. Its compact dimensions (54 mm wide, 75 mm high and 80 mm deep) allow for easy installation even in limited space.

Functionality and application

The Z-MS-0.40/3 starter is designed to protect motors with a power of up to 0.09 kW at a voltage of 400 V. The setting range of the overload release (0.25 – 0.4 A) allows for precise adjustment to the load characteristics, and the instantaneous short-circuit release (3.1 – 4.8 A) ensures a quick response in the event of a dangerous short circuit. This starter finds application in a wide range of devices, from pumps and fans to machines and industrial equipment. Thanks to its solid construction and high-quality materials, it guarantees long-lasting and trouble-free operation.

Characteristics and benefits

• Thermal protection: Built-in thermal protection protects the motor from overheating caused by overload, which extends its lifespan.
• Short-circuit protection: A fast-acting short-circuit release minimizes the risk of damage to the motor and installation in the event of a short circuit.
• Easy installation: Screw connection of the main contacts facilitates cable connection, and the lever of the actuator ensures convenient operation.
• High reliability: The design as a complete device in a housing ensures stable operation and resistance to external conditions (IP20 protection degree).
• Rated breaking capacity: Breaking capacity of 10 kA at 400 V AC guarantees effective disconnection of the circuit in the event of a failure.
• Precise adjustment: The ability to adjust the setting range of the overload release allows for optimal adaptation to the specific motor load.
• Safety: Compliance with safety standards confirmed by the CE marking ensures safe operation of the device.
