info

Do you have limited behind-panel space for installing a battery disconnect? The SR Series Heavy-Duty High-Cranking Single-Pole Master Battery Disconnect Switch with Rotary Knob features a low profile that's only 3.1" deep or less, making it an ideal solution that allows you to cut off battery power for safety when the vehicle is being serviced or for preventing battery drain when the vehicle is stored.

This manual disconnect switch with a built-in rotary knob can be installed anywhere on a vehicle thanks to its corrosion-free thermoplastic body and ingress protection to either an IP66 rating or IP67 and IP69K ratings. It is also ignition protected to SAE J1171 and ISO 8846 for installation in a battery box or on vehicles carrying hazardous loads.

  • Available with 48 V, 32 V, and 16 V max operating voltage and 5 A to 600 A max continuous current ratings to suit a wide range of applications
  • 3.1" or less depth allows installation in areas with limited space
  • Configurations are available with a built-in lockout/tagout (LOTO) hole
  • Thermoplastic construction with either an IP66 rating or IP67 and IP69K ratings stands up to roadsplash and salt spray
  • Ignition protected to SAE J1171 and ISO 8846 for installation in a battery box or on vehicles carrying hazardous loads
