Motor protection circuit breakers – reliable protection for your drives

MS132 motor protection circuit breakers are devices designed for comprehensive protection of electric motors, providing both overload and short-circuit protection. The construction based on thermomagnetic technology guarantees a quick and effective response in emergency situations, minimizing the risk of damage and downtime. This device finds application in a wide spectrum of applications – from simple home installations to advanced industrial systems.

Construction features and application

The MS132-1.0 circuit breaker is characterized by compact dimensions (45 mm width, 90 mm height and 86.75 mm depth), which facilitates mounting even in limited spaces. Designed to operate in circuits with a rated voltage of 250…690 V, it allows for the protection of motors with a power of up to 0.25 kW at 400 V AC. The adjustable setting range of the overload release (0.63…1 A) allows for precise adaptation to the characteristics of the protected circuit. It is worth emphasizing that this circuit breaker is compatible with both single-phase and three-phase applications, which increases its versatility.

Advantages and benefits

• Effective protection: Provides reliable motor protection against overload and short circuit thanks to the use of a thermomagnetic release.
• Versatility: Possibility of use in single-phase and three-phase circuits expands the range of applications.
• Compact dimensions: Facilitate mounting in tight installation spaces.
• Current adjustment: Smooth adjustment of the overload release setting range allows for precise adaptation to the needs of a specific application.
• High short-circuit breaking capacity: The rated short-circuit breaking capacity Icu at 400 V AC is as high as 100 kA, which guarantees the safety of the installation even in the event of high short-circuit currents.
• Phase failure sensitivity: The built-in phase failure detection function further increases the safety of motor operation.
• Simple mounting: Connection of the main contacts using screw connection ensures quick and reliable cable mounting.
• TRIP indicator: Informs about the operation of the protection, making it easier to diagnose installation problems.

The MS132-1 circuit breaker is a solid solution for professionals and end-users looking for reliable protection for their electric motors. Thanks to its construction and functionality, it is an optimal choice for various industrial and domestic applications. Additionally, the ability to lock the handle provides additional safety during maintenance or service work.
