500 Amp magnetic latching (bi-stable) solenoid provides switching under load where manual control is not required

Remote Control Contura Switch not included p/n 2155

  • 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

  1.  Manual control switch provides an added level of safety allowing control with or without power, and offering LOCK OFF capability for servicing.
  2. Auto-Releasing provides 500A switching and features of current ML-RBS, but can be controlled with SPST or SPDT switch for applications where a normally open relay is desired
  3. The Maximum Current the switch is designed to conduct for an indefinite period
  4. The maximum amount of current a switch is designed to carry for a minimum of a designated period of time.
  5.  Normally associated with 'cranking current' which is the current required by the starter circuit prior to engine starting. The cranking current varies significantly during the starting cycle. Initially, there is a large surge of current required to overcome the inertia and compression of the engine. This surge can be two to four times the average cranking current. Once the engine is turning there are peaks and valleys as the pistons go through the compression and exhaust cycles. The cranking current rating is used for sizing batteries, cables, and battery switches.
