Danfoss 017-521566 RT121 Pressure Switch R-410A Its low-voltage wiring configuration allows

Its low-voltage wiring configuration allows for seamless integration into existing Maxitrol modulation systems

the regulator must be installed so the vent faces downward (typically the 6 o'clock position) to prevent water

Designed for commercial and industrial applications

while also providing a 30 to 90-second post-purge cycle to safely dissipate residual heat after the burner shuts down

It is engineered to withstand the thermal cycling common in mid-to-high-efficiency heating systems

Danfoss 017-521566 RT121 Pressure Switch R-410A Its low-voltage wiring configuration allowsThe Danfoss 017 521566 RT121 Pressure Switch is a heavy duty single pressure control designed for industrial refrigeration and general process monitoring. Engineered with a changeover switch (SPDT), this unit offers reliable performance in both plant automation and safety alarm circuits. It features a regulating range of 1 to 0 bar ( 14. 5 to 0 psig), making it an ideal choice for low pressure applications requiring precise setpoint accuracy. The
