SENASYS
Heat Sequencers
KSD Series
Senasys Heat Sequencers (KSD Series) are great for unique applications that require a time delay.
Our quality-engineered heat sequencers are designed for a variety of applications, including baseboard heaters, heat pumps, and electric furnaces.
These robust Heat Sequencers can be used in high current applications, carrying up to 25 amps at 277VAC for 100,000 cycles. These switches are available in a single-pole, single-throw (SPST), single-pole, double-throw (SPDT), or double-pole, single-throw (DPST) device.
Senasys Heat Sequencers have an operating range of -40°F to 150°F, making them a versatile and flexible component of any electric heating system.

Senasys Heat Sequencers are quality engineered sequencing thermostats specifically for a variety applications including baseboard heaters, heat pumps, and electric furnaces. A sequencer is a type of snap disc that uses multiple sets of contacts and a solid-state positive temperature coefficient (PTC) heater to switch on a delay. This causes different segments of a system to be turned on and off at different times. One to three sequencing switches are attached to a plate to form a complete sequencing unit.
To ensure that a safe combination of heat sequencer and application is achieved, the purchaser must determine product suitability for their individual requirements.
