Noark Electric’s Introduces A40 Power Circuit Breakers

September 19, 2023

Noark Electric’s Introduces A40 Power Circuit Breakers

Noark Electric’s A40 Power Circuit Breakers are available up to 4000 amps and are capable of interrupting ratings up to 100kA at 635V and 85kA at 847V. UL Listed and CSA Certified, the A40 family of products provide design standardization for OEM’s no matter where they do business. A40 breakers offer a broad range of available trip units, accessories, and communications options. They are the ideal OEM solution for low voltage switchgear and customized power distribution assemblies used in Data Centers, Standby Power, Industrial, Healthcare and Commercial applications.

Noark’s A40 Power Circuit Breakers and the accessories conform with ANSI C37.13, C37.16, C37.17 and C37.50 standards and are UL 1066 certified.

Circuit breakers are essential electrical safety devices that are designed to protect electrical circuits from damage caused by overcurrent. Their main function is to interrupt the flow of current to protect equipment from overcurrent faults and prevent the risk of fire or loss of property. Customers need a reliable way to prevent electrical overload or damage to their electrical systems and Noark’s A40 Power Circuit Breakers do just that. They are designed to protect cables and downstream equipment including feeders and electrical loads. They act as automatic switches that trip or open when they detect a surge or excess current flowing through a circuit.
