500 Amp magnetic latching (bi-stable) solenoid provides switching under load where manual control is not required
  • Includes ML-Series Remote Control Contura Switch 2145
  • 500 Ampere continuous rating for engine, inverter, house loads, and emergency battery combine
  • Magnetic latching draws no current in "ON" or "OFF" state, only draws current when changing state of switch
  • Silver alloy contacts provides high reliability for switching live loads
  • 3/8" -16 tin-plated copper studs for maximum conductivity and corrosion resistance
  • 7/8" (22mm) stud length accepts multiple cable terminals
  • Label recesses for circuit identification

*Manual controll switch provides an added level of safety allowing control with or without power, and offering "LOCK OFF" capability for servicing.
**Auto-Releasing provides 500A switching and features of current ML REmote Battery Switches, but can be controlled with SPST or SPDT switch for applications where a normally open relay is desired
***The maximum current a switch is designed to conduct for an indefinite period.
****The maximum amount of current a switch is designed to carry for a minimum of a designated period of time
*****Normally associated with "Cranking Current" which is the current requried by the starter circuit prior to engine starting. The cranking current varies significantly during the starting cycle. Initially there is a large surge current required to over come the inertia and compression of the engine. This surge can be two to four times the average cranking current. Once the engine is tunring there are peaks and valleys as the psitons go through the compression and exhaust cycles. The cranking current rating is used for sizing batteries, cables and battery switchs.
******The maximum amount of current a switch is designed to carry when starting an engine when the cranking period does not exceed 1 minute.
