Compact circuit breakers—commonly known as MCCBs (Molded Case Circuit Breakers)—reliably protect electrical systems and machinery against overloads and short circuits. The Schneider Electric ComPacT series combines a compact design with high breaking capacity and is specifically designed for industrial use in control panels, machinery, and power distribution systems.
| Series | ComPacT NSXm | ComPacT NSX | ComPacT NS |
|---|---|---|---|
| Current range | up to 160 A | up to 630 A | up to 3,200 A |
| Breaking capacity | up to 70 kA (415 V) | up to 200 kA (415 V) | up to 125 kA (415 V) |
| Typical Applications | Compact control cabinets, Motor protection | Industry, equipment protection, Distribution panels | Main distribution panels, Power distribution |
All ComPacT Schneider Electric circuit breakers are designed for use in industrial environments and comply with current standards for equipment and motor protection. BLEMO can help you select the right series—whether for a new installation, an expansion, or the replacement of existing equipment.
Open-type circuit breakers—also known as ACBs (Air Circuit Breakers)—are used wherever high currents need to be safely switched and protected. The Schneider Electric MasterPact MTZ series offers high-performance solutions for main distribution boards, industrial facilities, and building automation.
| Size | MasterPact MTZ1 | MasterPact MTZ2 | MasterPact MTZ3 |
|---|---|---|---|
| Electrical sector | 630 A – 1.600 A | 800 A – 4.000 A | 4.000 A – 6.300 A |
| Typical Applications | Sub-distribution panels, medium-sized industrial facilities | Main distribution panels, large-scale facilities | Power distribution centers, heavy industry |
Load break switches and circuit breakers serve different purposes in an electrical system: While circuit breakers trip automatically in the event of a fault to interrupt short circuits or overload currents, load break switches are primarily used for the safe manual switching and electrical isolation of circuits—for example, for maintenance and service purposes.
The Schneider Electric FuPacT, ComPacT NA, and MasterPact series offer the right solution for every application—from 32 A for small machines to 6,300 A for large power systems.
| Current range | from 32 A to 6300 A, depending on the series |
|---|---|
| Typical product series | FuPacT up to 800 A, ComPacT NSXm NA up to 160 A, ComPacT NSX NA up to 630 A |
| Technical Specifications | Up to 690 V AC depending on the model, some models: AC-22A and AC-23A |

A circuit breaker automatically protects electrical systems against overloads and short circuits—it trips automatically in the event of a fault.
A load break switch, on the other hand, is used for the manual, safe disconnection and switching of electrical circuits, for example during maintenance and service work. To ensure complete protection, these two components are often used in combination.
That depends on several factors: rated current, short-circuit requirements, installation location, and operating concept.
The ComPacT series (NSXm, NSX) is recommended for currents up to 630 A and compact control cabinets. For main distribution panels ranging from 630 A to 6,300 A, the open-type MasterPact circuit breakers are the right choice. BLEMO offers free technical consultation to help you make the right selection.
Yes. BLEMO is an official Schneider Electric IAD (Industrial Automation Distributor) partner and service reseller. You can request circuit breakers, disconnect switches, and accessories directly from us—we’ll provide technical advice, confirm availability, and ensure reliable delivery.
MCCBs (compact circuit breakers) are rated for currents up to approximately 3,200 A and are primarily used in control panels and machinery.
ACBs (Air Circuit Breakers) cover the high-current range from 630 A to 6,300 A and are used in main distribution panels and large power systems. ACBs are more complex in design and offer advanced protection functions.
Yes, many solutions are specifically designed for industrial control cabinets, machines, and power distribution systems. It is important to choose the right solution for your specific application.
Yes. We can help you identify suitable replacement models for older circuit breakers and load break switches—including those from other manufacturers. Our experts will verify technical compatibility and availability, and assist with commissioning.
