Song Chuan NC/NO Change Over Relay - Flux Tight

Song Chuan's flux tight relays are designed for superior performance in marine applications and other automotive uses, offering sealed dust resistance, tinned terminals for corrosion protection, and an internal resistor to guard against voltage spikes. The internal contacts have been redesigned for greater overtravel, a larger solid contact area, and increased NC contact force, ensuring a better connection and reducing the risk of arcing. This improvement allows for more current to flow through, or longer cycle life at the same current. Additionally, the flux tight housing prevents the ingress of smaller particles and liquids, enhancing overall durability compared to previous models that only featured a dust cover.

• Tinned terminals and flux tight housing makes this relay perfect for marine use.
• Mechanical life - no load = 1,000,000 cycles at +85°C the N.O. contacts will carry a continuous load of 50A.
• Operating Ambient Temperature: -40°F to 257°F (-40°C to +125°C).
• Between Open Contact Contact and Coil: AC 1000V, 50/60Hz 1 min.
• RoHS & ELV Compliant.
• Contact Material: AgSnO alloy.
• Part Number 74990 is a substitute for 73990
• Enhanced durability with flux tight housing preventing ingress of particles and liquids
• Redesigned internal contacts for greater overtravel and solid contact area
