Egis Mobile Electric 4707-120 Circuit Breaker Series Panel Mount - 120A 87

The Egis Mobile Electric 4707-120 is a 120-amp, 87 Series panel mount circuit breaker engineered for demanding marine, RV, and mobile electrical installations. It delivers dual-function automatic overcurrent protection and manual on/off switching in a single compact, weatherproof unit, safeguarding DC circuits from short-circuit events and thermal overloads that can cause wire insulation damage.

Designed with a circular cutout-compatible form factor, this breaker installs cleanly into standard panels and supports mounting adjacent to battery systems for flexible placement. Its IP66-rated sealed housing and high-temperature-rated materials make it well-suited for engine compartments, bilges, and other harsh environments.

Key Features:

• IP66 sealed against dust and water intrusion for reliable, long-term circuit protection
• 48V DC max voltage rating — fully supports 12V and 24V systems while providing advanced protection for 36V and 48V DC applications
• High interrupt current capacity — 5,000A at 14V DC and 3,000A at 28V DC to safely protect circuits connected to large or parallel battery banks
• 2,000-cycle switching endurance at full current for lasting manual and automatic operation
• Ignition protected — safe for installation in enclosed compartments where explosive gases may be present
• Circular cutout design for straightforward panel installation
• Stainless steel hardware with serrated flange nuts and silicone terminal covers for corrosion and vibration resistance
• Meets ABYC E-11 interrupt requirements
• Visual circuit-open indication via bright yellow paddle, which also serves as the reset actuator
• High-temperature rated materials suitable for engine compartment use
• 4-year warranty

The Egis Mobile Electric 87 Series 4707-120 is an ideal solution for protecting high-current DC circuits in marine, overland, and mobile power applications where reliability and environmental resilience are critical.
