Eaton / Cutler-Hammer RGH316033E Molded Case Circuit Breaker

The RGH316033E is a standard 80% rated circuit breaker [1.1.1]. In compliance with typical National Electrical Code (NEC) sizing guidelines, it is engineered to carry up to 80% of its 1600A maximum capacity continuously (1280 amps) in standard enclosed applications.

In Eaton's Series G nomenclature, the E suffix indicates that the breaker is equipped with English (Imperial) threaded line and load terminal pads. Variants ending in M feature Metric tapped pads.

Yes. The included Digitrip 310 electronic trip unit features adjustable dials for both long-time and short-time (LS) pickup and delay. This flexibility allows electricians to accurately coordinate the breaker with specific load characteristics and downstream protective devices.

No. This specific breaker is equipped with an LS (Long-Time, Short-Time) trip unit. It does not provide integral ground fault (G) protection. If equipment ground fault protection is required by the NEC for your installation, you will need an LSG or LSIG trip unit, or an external ground fault relay system.

This high-capacity RG-frame breaker is designed for heavy industrial and commercial power distribution. It is commonly unit-mounted in Eaton Pow-R-Line panelboards, large switchboards, and motor control centers (MCCs).

The RGH316033E uses a solid-state electronic trip unit (the Digitrip 310) utilizing an adjustable rating plug. Electronic trip units provide true RMS sensing, superior accuracy, and more precise curve shaping compared to standard thermal-magnetic breakers.

The H designates this as a high-interrupting capacity breaker within Eaton's RG-frame family. It delivers robust fault protection with a maximum interrupting rating of up to 125 kA at 240V AC and 65 kA at 480V AC, making it suitable for systems with high available fault currents.
