time delay relays and sequencers

KSD90 Series time delay relays and sequencers are field-proven for controlling the operation of heating elements and/or fans in electric furnaces and heat pumps.These controls combine a solid-state positive temperature coefficient (PTC) heater with bimetal actuated contacts to provide time-delayed electrical switching.A wide variety of bimetal disc and PTC combinations are available to provide a broad range of timeings.

Features:

*Available with auto-reset SPST,DPST and SPDT switch configurations.

*PTC heater for stable operation over a wide range of temperatures and voltages.

*Snap-action bimetal disc for high-speed contact separation.

*Standard operating ambients between -40F(-40C) and 165F(73.9C).

*Available with a wide variety of terminals and mounting plates.
