EGIS™ 85 Series Surface Mount Circuit Breaker 40-150 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. Sealed against dust & water intrusion. High voltage (48 VDC) rating easily supports 12 and 24 VDC applications while offering improved protection for 36 and 48 VDC systems rather than using fuses. High electrical/manual switching endurance delivers 6,000 cycles at full current. High interrupt current safely protects circuits connected to large, paralleled battery banks with significant available power.
