Product Details

The Egis Mobile Electric 285 Series 100A Surface Mount Circuit Breaker provides robust electrical circuit protection against short-circuit events and over-current loads, preventing wire insulation damage and system failure. This marine-grade circuit breaker combines automatic protection with manual on/off switching in a compact, surface-mountable design ideal for battery-powered applications.

Key Features:

  • IP67 Sealed Protection: Fully sealed against dust and water intrusion for reliable performance in harsh marine, RV, and mobile environments
  • High Voltage 48 VDC Rating: Supports 12V, 24V, 36V, and 48V DC systems with continuous 100-amp capacity
  • High Interrupt Current: Safely handles 5,000 amps at 16 VDC and 3,000 amps at 28 VDC, ideal for large battery bank installations
  • Extended Cycle Life: Rated for 6,000 electrical and manual switching cycles at full current load
  • High-Visibility Controls: Easy-to-operate ON/OFF toggle with clear position indication
  • Integrated Terminal Insulators: Built-in protection prevents accidental shorts between positive terminals and grounded surfaces
  • Corrosion-Resistant Hardware: Stainless steel mounting hardware with serrated flange nuts resist corrosion and vibration
  • Surface Mount Design: Mounts directly adjacent to battery systems for convenient circuit isolation and maintenance access

Technical Specifications:

  • Continuous Current Rating: 100 Amps
  • Maximum Voltage: 48 VDC
  • Interrupt Current: 5,000A @ 16 VDC / 3,000A @ 28 VDC
  • Cycling Endurance: 6,000 cycles
  • Ingress Protection: IP67 (dust-tight and water-resistant)
  • Construction: Made in USA
  • Warranty: 4 Years

Ideal for marine vessels, RVs, off-grid solar systems, electric vehicles, and other mobile power applications requiring reliable overcurrent protection and circuit isolation. The 285 Series breaker's dual functionality eliminates the need for separate switches and fuses, simplifying electrical system design and reducing potential failure points.
