Eaton Corp. has expanded its circuit breaker capabilities to offer enhanced ground fault protection and nonfused current-limiting breaker modules for the Series G circuit breakers with the release of the Earth Leakage Modules and the current-limiting breaker modules. Equipped with a built-in sensor and ground fault relay, Eaton’s Earth Leakage Modules are designed to protect against equipment damage and increase personnel safety by limiting current. Additionally, the current-limiting breaker modules are designed to meet the increasing capacity of electrical source, providing increased fault currents. They provide advanced system protection during overloads and both low- and high-level short circuits.

Eaton’s current limiter module provides automatic reset after interruption, unlike fused current limiters with a one-time use. Eaton manufactures nonfused current limiting modules in combination with Series G E-Frame breakers with interrupting capacities up to 150 kA at 480 Vac.
