BEP Marine 720-MDO Battery SwitchRemote Operated Battery Switch w/Optical Sensor 500A 12/24VThe MD range of battery switches allow you to install the battery switch very close to the battery, to remotely manage the increased electrical loads found on today's boats. This reduces cable lengths and sizes, providing significant savings in expense and weight of copper battery cable. They are ideal for remote isolation of bow and stern thrusters. The 720-MDO has been enhanced to offer easy standard installation, or advanced options capable of switching different voltage circuits from the main supply (for example: a 48 volt bow thruster with a 24 volt house supply). The optical sensor uses the same easy connection for standard installation and gives you the ability to control different voltage circuits such as 36 or 48 volts. It can be used to switch positive or negative lines and the main contacts can be isolated from the control circuit allowing operation via another battery source. This optical sensor also has low stand-by current draw (<5mA). Remote operation Battery switch can be mounted alongside battery, reducing cable lengths and cable sizes. (Large cost and weight saving in copper cables) Reduced installation labor due to shorter battery cable runs Manual override option to meet CE/ABYC requirements LED status identification for remote control switch Same capacities/specifications and mounting options as standard BEP battery switches Uses interchangeable labeling system (Item # 713 or 715) Specifications:LxWxH: 4" x 4" x 4.33"Rating (A DC) Cont: 500Rating (A DC) Inter: 700Rating (A DC) Crank: 2500Voltage (V DC): 9.5-32Function: On/OffStud Size: 2x (1/2"/12mm)WARNING: This product can expose you to chemicals including di(2-ethylhexyl)phthalate (dehp) which is known to the State of California to cause cancer, birth defects or other reproductive harm.

Perko 8502DP Battery Switch Medium Duty Battery Selector Switch w/Key Lock Perko's 8501 Series battery selector switches are among the most popular battery switches ever produced. Their use of the traditional Perko bolt circle makes for easy installation, whether new or as a replacement. These switches can be mounted in numerous locations. As ignition-protected switches, they can be installed in the engine rooms of gasoline-powered boats. In addition to doing everything a battery disconnect switch does, battery selector switches permit battery selection (of two or more batteries) for specific purposes including starting engines, running accessories, or even recharging. They allow for the use of one or more batteries in systems with one or more engines and facilitate putting batteries in parallel for emergency starting when one or both batteries are substantially discharged. Perko battery switches are designed for surface mounting. Standard duty switches have a bright red polycarbonate housing for safety with a large easy-to-turn black knob. The housing of the heavy-duty switches are red fiber-reinforced polycarbonate. Selector switches are designed with a "make before break" feature. This allows switching between the "1", the "ALL" and the "2" positions while the engine is running. Models with an "Alternator Field Disconnect" feature offer protection for Non-Unitized Alternators should the switch accidentally be turned to the "OFF" position with the engine running. Versions of the 8501 Series switches offer additional features such as alternator disconnect and key lock security. The 90° rotation feature allows users to feel the switches' position in no light situations and the classic shape of the knob makes it easy to turn. High conductivity studs are long enough to handle more than 1 cable and strong enough for the torque needed for secure connections. The optional spacer ring (PN 0462DP0RED) allows for the use of larger cables. Specifications: Diameter: 5-1/4" Depth: 2-5/8" For use with 6 to 50 Volt Marine Electrical Systems Capacity - 250 AMPS Continuous, 360 AMPS Intermittent When used with Non-Unitized Alternators, these models will interrupt the field current (reducing the possibility of damage) if turned "OFF" with the engine running Electrical: Battery Switch Normalized SKU: 8502DPUPC Code: 085226559624 WARNING: This product can expose you to the chemical lead, which is known to the State of California to cause birth defects or other reproductive harm.
