Relay double pole.

A double throw switch connects an input terminal to one of two output terminals. Rl power relay key features. That is a common terminal connects to either of two others never connecting to both at the same time. Single pole rated at 30a double pole at 25a.

Flange mount or din rail mount with panel mount tabs. These 12v dpdt relays are small but ideal for projects to allow various control options including changing the direction of a motor. Dpdt stands for double pole double throw relay which is an electromagnetic device used to separate two circuits electrically and connect them magnetically. Panasonic ds2y s dc5v electromechanical relay double pole double throw 2a 5 volt 125 ohm pack of 2 13 73 13.

Two for incoming hots and two for outgoing hots. Designed for motor lighting and heater loads. Ac or dc coil inputs. It has 2 terminals and 4 connectors and you can look at the dpdt relay as the equivalent of 2 single pole double throw spdt relays.

Standard din numbers of a relay circuit. 73 6 87 relay get it as soon as fri oct 2. Song chaun 3 pole relay 24vac coil 20a 277v rated contacts panel mount. Panasonic ds2y s dc5v electromechanical relay double pole double throw 2a 5 volt 125 ohm pack of 2 13 73 13.

The other two terminals are often referred to as a and b. A double pole switch is what you need to control a 240 volt device because 240 volt circuits have two hot wires. Including two for the coil such a relay has a total of five terminals. When the switch is in one position the common terminal is connected to the a terminal so current flows from the common terminal to the a terminal but no.

Up to 7500 va maximum switching power. It has four terminals. One of the terminals is called the common terminal. The difference between a single and double pole switch is that the latter controls two circuits at the same time.

And for those who prefer right brain pictures note that the photo doesn t show the 87a terminal as this is only used by single pole double throw changeover relays that are less commonly used than the four terminal single pole single throw spst relays described here. The dpdt relay double pole double throw is quite interesting and can be used in various scenarious including for changing the direction of a motor as you can see in the picture below. 0 250 quick connect tabs or screw terminals. 73 6 87 relay get it as soon as thu oct 1.

Spdt single pole double throw relays have a single set of form c break before make or transfer contacts.
