Egis Mobile Electric 4730-20 Short Stop 20 Amp Marine Circuit Breaker

The Egis Mobile Electric 4730-20 Short Stop is a compact, surface-mount marine-grade circuit breaker rated at 20 amps, designed to deliver resettable circuit protection for low and medium ampere circuits in demanding marine and mobile electrical systems.

This breaker protects electrical circuits from short circuit events and dangerous over-current loads, preventing wire insulation from overheating and subsequent damage. Its ignition-protected design makes it safe for installation in closed compartments where explosive gases may be present — a critical feature for marine engine rooms and fuel storage areas.

Key Features:

• 20 Amp continuous current rating for low and medium ampere circuit protection
• 28 Vdc rating — fully supports both 12V and 24V DC marine electrical systems
• Manual Reset – Type III operation allows easy re-closing of the breaker once a fault is cleared
• Ignition protected — safe for use in enclosed spaces with potential explosive atmospheres
• Weather resistant construction guards against dust and water intrusion for long-term reliability
• Compact surface-mount design minimizes panel space requirements
• Compatible with Egis Mobile Electric MT Series Sealed Fuse/Circuit Breaker Blocks
• Color-coded enclosure (yellow for 20A) helps prevent installation errors and ensures correct replacement

The Short Stop 4730-20 is an ideal upgrade over traditional fuses, offering the convenience of resettable protection without the need to carry spare fuses onboard. It is well-suited for protecting branch circuits on boats, marine vessels, RVs, and specialty vehicles where reliability in harsh environments is essential.
