Bosch-Tyco Hi-Amp Relays - 75 Amp, 12V

The Bosch-Tyco single pole single throw (SPST), high current relays can switch up to 150A with minimal contact resistance. Ideal for use with engine control, glow plug, heated front- and rear - screen, preheating systems (e.g. for diesel engines, catalytic converters), switches for loading ramps, power distribution. These relays are IP54 and IP67 rated.


  • Life Expectancy Mechanical = 1,000,000 Operations.
  • Dielectric Strength Between Contact and Coil: AC 500V, 50/60Hz 1 min.
  • Operating Ambient Temperature: -40⁰C to 125⁰C (-40⁰F to 257⁰F).
  • Contact Material: Ag Alloy.
  • Operate/release time typ. at nominal voltage: 7/2ms.
  • Life Expectancy Electrical = Normally Open, resistive load 75A, 13.5VDC > 100,000 operations. 50A, 27VDC > 50,000 operations.
  • Rated coil voltage: 12/24V DC.
  • Torque on each M5 screw must be ≤ 2.8 Nm.
