PowerPact B molded case circuit breakers (MCCB) benefit from 60 years of expertise and leadership in industrial circuit breaker technology, in a new smaller frame size.

Global Design

• One design for the world with standardized ratings and a full range of accessories make product selection, installation and maintenance easier
• Reduce inventory with shared accessories and auxiliaries with Compact NSXm

Easy and Efficient

• Flexible installation for your convenience: Click your circuit breaker into place with the built-in DIN rail - no extra parts required. Alternatively, vertical plate mounting means you can save space
• EverLinkTM connectors for reliable and quick bare cable connections
• Field-installable one-click auxiliaries and accessories
• Save time when you use the Product Selector tool to order your multistandard MCCB

Enhance Equipment Protection

• All PowerPact Multistandard circuit breakers are equipped with dual-break rotating contacts that reduce the amount of peak current during a short circuit fault. This reduces the let-through currents and enhances equipment protection.
