2-Position 275A Battery Isolator Switch with AFD
$59.90
1 Year Warranty
The switches themselves are very durable and rated for massive output. They feature removable windows on all four sides to cater for whatever cabling arrangement you have. Alternator Field Disconnect (AFD) protects your alternator when switching batteries in and out of the circuit. By disconnecting the alternator moments before the battery (moments after when re-engaging), there’s always a load on the alternator to protect the regulation circuitry.

Two models available:
SF-2249 275A Battery - On / Off
SF-2250 200A Dual Battery - 1 / 2 / Both / Off

Features:
• High rated current
• Protects your alternator
• Versatile cable entry
• Continuous Current: 275A
• Surge Current (5min): 455A
• Cranking Current (10sec): 1250A
