Low-power PCB relays are available from TE Connectivity (TE) with one or two poles and maximum contact ratings ranging from 3A to 16A. This means that they can be used to meet a variety of isolated switching requirements in the control circuits in intelligent buildings.

Relays with a high 16A contact rating include the 0410 83, a board-mount, 1 Form X relay which offers a contact gap of more than 3mm. Also offering a 16A rating are the OMIH, which offers 5kV of contact-to-coil isolation, and the RT and RZ series, which include models rated for operation at high temperatures.

TE also supplies the RT (Inrush) relay, which is rated for a 16A maximum current in normal operation, but which can withstand an inrush current of up to 80A. The RTX model can withstand inrush currents of up to 320A.
