Eaton CSR2125N Circuit Breaker

The Eaton CSR2125N is a 2-pole main circuit breaker rated for 120/240-volt systems with a 125-amp capacity. As the primary service disconnect, it interrupts both hot legs to protect feeders and downstream circuits in overcurrent conditions, helping to prevent wiring damage and equipment failure. The two-pole design ensures simultaneous interruption of both conductors, which is essential for safely disconnecting 120/240-volt loads and for proper trip coordination within a panel. This unit is intended for use as the main breaker in electrical distribution setups that require a 125-amp, 2-pole protection device, offering a reliable, straightforward solution for residential or light commercial installations that need a single-point disconnect at the service entrance.
