Egis Mobile Electric 4720-20 ATM/Mini 20 Amp Resettable Circuit Breaker Type 3

The Egis Mobile Electric 4720-20 is an ATM/Mini-footprint, 20-amp resettable circuit breaker designed for compact, high-density circuit protection in marine, RV, and mobile electrical systems. Its extremely small form factor allows multiple breakers to be mounted in close proximity, maximizing protection coverage in tight spaces without sacrificing reliability.

Rated at 32V DC maximum, this breaker is well-suited for both 12V and 24V DC electrical systems. The Type 3 push-to-reset operation keeps the breaker in the tripped (open) position after a fault until the operator manually resets it — ensuring any fault condition is investigated and cleared before restoring power.

Built for demanding environments, the 4720-20 features high-temperature materials and tin-plated copper alloy conductors to resist corrosion and withstand harsh conditions including shock and vibration. The housing is sealed against dust and water intrusion and is ignition protected, making it safe for use in enclosed compartments where flammable or explosive gases may be present.

The breaker's color-coded yellow enclosure (standard for the 20-amp rating) helps prevent installation errors and ensures easy identification for correct replacement. It is also compatible with Egis MT Series Sealed Fuse/Circuit Breaker Blocks for use in integrated protection panels.
