187 Series EGIS Circuit Breakers - Diagram 2

EGIS Series 187 circuit breakers provide dependable thermal circuit protection for demanding marine and harsh-environment applications. Designed for auxiliary and accessory circuits in boats, trucks, buses, and RVs, they combine automatic overcurrent protection with manual on/off switching in a compact, durable design. A bright yellow paddle provides visual indication when a circuit opens and allows convenient manual resetting.

Featuring sealed IP66 construction and ignition protection to SAE J1171, Series 187 breakers are suitable for installation in engine compartments and enclosed areas where exposure to moisture, dust, and potentially explosive gases is a concern. Supporting systems up to 48 VDC, they offer a 1,500-amp short-circuit interrupt rating and meet ABYC E-11 interrupt requirements. Stainless steel self-locking hardware, high-temperature materials, and UL 94 V-0-rated construction provide added durability and reliable performance in demanding environments. Contact a Pacer Marine specialist for assistance selecting the right circuit protection for your application.

 

Characteristics:

  • Sealed Against Dust & Water Intrusion to ensure reliable circuit protection for the life of the electrical system installation
  • High Voltage (48 VDC) Rating easily supports 12 and 24 Vdc applications while offering advanced protection for 36 and 48 Vdc applications
  • Meets New ABYC E-11 Interrupt Requirements
  • High Interrupt Current safely protects circuits connected to large paralleled battery banks with significant available power
  • Ignition-protected safe for installation in closed compartments with potential
    explosive gases

Features:

  • Protects electrical circuits from short-circuit events and overcurrent loads, preventing wire insulation overheating and subsequent destruction.
  • Automatic circuit protection and manual on/off switching combine dual functionality in one reliable and compact solution.
  • Bulletproof construction: sealed device, high-temp materials for engine compartment applications, and stainless self-locking hardware.
  • Visual indication of a circuit opened with a bright yellow paddle, also used for resetting to on.
  • Harsh environment design with stainless steel hardware and self-locking terminal nuts.
