NB221060 - 60Amp Circuit Breaker

NB221060 - 60Amp Circuit Breaker

The NB221060 60 Amp circuit breaker is designed to provide reliable overcurrent protection for 120/240V electrical systems in both residential and commercial settings. Built with a double pole configuration, this breaker helps protect both legs of a 240V circuit at the same time, making it a dependable choice for higher-demand applications. Its thermal magnetic trip mechanism responds to sustained overloads as well as sudden short circuits, helping prevent damage to wiring and connected equipment. With a secure bolt-on mounting style and a 10kA interrupting rating, the NB221060 delivers steady, consistent protection where it matters most.

Key Features and Benefits

• 60 Amp Capacity: Suitable for circuits that power larger equipment or higher electrical loads.
• Double Pole Protection: Simultaneously protects both ungrounded conductors in 120/240V systems.
• Thermal Magnetic Trip: Designed to trip on overloads (thermal) and short circuits (magnetic) for balanced protection.
• Bolt-On Connection: Fastens directly to the panelboard bus for a secure and stable installation.
• 10kA A.I.C. Rating: Rated to interrupt up to 10,000 amps at 120/240VAC.
