The Dayton 3x741E General Relay is a versatile and reliable electrical component suitable for various applications. This 10 amp, 11-pin coil relay has a compact size (2.48 inches long, 1.33 inches wide, and 1.05 inches high), making it an excellent choice for space-constrained installations. With a NEMA size 1, it is well-suited for applications requiring a standard relay footprint.
This Dayton General Relay features a 10 amps contact rating, which allows it to handle a significant electrical load. The 11-pin configuration provides multiple normally open (NO) and normally closed (NC) contacts to accommodate diverse switching requirements. Brothers Company organizes the pins for the ease of identification; contacts 1 to 6 are normally open and pins 7 to 11 are normally closed. The 30 VAC/60 VDC operating voltage range makes it adaptable to different voltage systems.
The Dayton 3x741E is a coil-operated relay with a decisive 250 ohms contact resistance. Its operating temperature ranges from -40 C to 85 C (-40 F to 185 F), making it capable of handling a wide range of environmental conditions. This reliable relay is also known for its minimal inrush current of 2.1 amps, ensuring smooth switching operations with minimal power loss. Another notable feature includes its robust contacts rated for 100 million operations under ideal conditions.
