Motor protection circuit breakers – reliable protection for your drives

Motor protection circuit breakers are key elements in protecting electric motors, shielding them from overload and short circuit. These devices not only ensure the safety of the installation but also minimize the risk of costly downtime caused by failures. The MS132-10 model, with a rated current of 10A, is a compact and efficient solution for protecting motors with a power of up to 4 kW (AC-3, 400V). Its versatility allows for use in both single- and three-phase installations.

Construction and functionality

The MS132-10 circuit breaker is characterized by a solid construction in a housing with dimensions of 45 x 90 x 86.75 mm. It has a thermal-magnetic tripping method, which means it reacts to both overloads (thermal release) and short circuits (electromagnetic release). Additionally, the built-in phase failure detection function increases the safety of motor operation. The adjustable overload release setting range (6.3 – 10 A) and short-circuit release setting (150 A) allow for precise adaptation to the load characteristics. It is worth noting that the device has a switching capacity Icu at the level of 100 kA at 400 V AC, which guarantees effective protection in the event of a short circuit.

Application and benefits

The MS132-10 circuit breaker finds wide application in industry, construction and workshops. It is ideal for protecting various types of equipment powered by electric motors – from pumps and fans to production machines. Thanks to its compact dimensions and the possibility of mounting on a TH35 rail, installation is simple and quick. Using this circuit breaker translates to:

• Motor protection: against overload, short circuit and phase failure.
• Installation safety: thanks to the high breaking capacity.
• Extended motor life: by preventing failures caused by improper operation.
• Ease of use: thanks to the knob with a clear indication of the switch position and the possibility of locking the handle.
• Versatility: possibility of use in single- and three-phase installations.
• Low power loss: amounting to only 6 W, which translates into energy savings.

The MS132-10 circuit breaker is a reliable solution for professionals and end users looking for effective protection of their electric motors. Its solid construction, precise settings and high breaking capacity guarantee safe and efficient operation for a long time.
