2903701

Power Relays, Over 2 Amps

The 2903701 is a power relay designed to operate in high current applications, such as those over 2 Amps. The relay is designed primarily for switching high current inductive loads, such as motor loads, lamps, and contactors. The current ratings makes the device suitable for a variety of industrial applications in motor controls, HVAC, lighting controls, and manufacturing equipment.

The 2903701 power relay has a 10A control circuit and is designed to switch up to 25A for AC loads or 18A for DC loads. The coil is rated at 95VAC/DC and operates on 45-55Hz. It comes in a plastic injection-molded housing measuring only 28.4 mm x 15.0 mm x 10.9 mm. The contact arrangement is two Form A (SPST) changeover contacts.

The operating principle of the2903701 power relay is simple. When the coil is energized, an electromagnetic field is created by the current flow. This force attracts the armature and causes it to close the contacts. This connection forms a circuit that allows current to flow through the load. When the coil is de-energized, the electromagnetic force weakens and the armature is released, opening the contacts and breaking the load\'s circuit.

The low-profile 2903701 power relay is well suited for applications that require substantial current switching but require a small package size. Its fast switching time and robust construction make it a reliable solution for a number of industrial applications. The device is RoHS compliant and approved for use in UL and CSA industrial applications.
