EGIS™ 87 Series Surface Mount Circuit Breaker 100 AMP. Protects electrical circuits from short circuit events and over-current loads, preventing wire insulation overheating and subsequent destruction. Automatic circuit protection and manual on/off switching combines dual functionality in one reliable and compact solution. IP 66 sealed against dust and 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. High electrical/manual switching endurance delivers 2,000 cycles at full current. High interrupt current safely protects circuits connected to large paralleled battery banks with significant available power.
