Reliable motor protection with Eaton Z-MS-4.0/2 circuit breaker

Eaton Z-MS-4.0/2 motor circuit breaker is a compact and efficient solution for protecting electric motors in single-phase installations. The device combines thermal and short-circuit protection, ensuring comprehensive safety for the motor and the entire installation. It is an ideal choice for both professional installers and end-users looking for reliable protection.

Functionality and application

The circuit breaker is designed to protect motors with a power of up to 0.37 kW at a voltage of 230 V AC-3. The rated continuous current of 4A and the adjustable overload release setting range (2.5…4 A) allow for precise adaptation to specific application needs. The use of a thermal-magnetic mechanism guarantees a quick response to overloads and short circuits, minimizing the risk of damage. Therefore, the device is perfect for protecting various devices such as pumps, fans, and conveyors.

Key features and benefits

• Dual protection: The thermal-magnetic mechanism protects against overloads and short circuits – ensures long-lasting and safe motor operation.
• Current adjustment: The ability to set the overload current in the range of 2.5-4 A allows for optimal adaptation to the load characteristics.
• High short-circuit capacity: The rated short-circuit switching capacity of 10 kA at 400 V AC guarantees effective circuit interruption in the event of a failure.
• Compact size: The modular design facilitates mounting in standard electrical cabinets and switchboards (dimensions: 75 mm x 36 mm x 80 mm).
• Durable connection: Screw connection ensures a secure and stable connection of wires, minimizing the risk of loosening connections.
• Renowned manufacturer: Eaton is a synonym for quality, reliability, and innovative solutions in the electrical industry.
• IP20 protection degree: Indicates protection against touching with a finger and solid objects larger than 12.5 mm – requires mounting in an enclosure or switchboard.

The Eaton Z-MS-4.0/2 circuit breaker is a solid and reliable device that will meet the expectations of even the most demanding users. Its simple construction and ease of installation make it an ideal choice for both professionals and individuals performing electrical installations themselves.
