The Allen Bradley 836-C4E is an explosion-proof pressure switch tailored for robust industrial use. This device utilizes actuator bellows made from a combination of copper alloy and 316 stainless steel, ensuring durability and reliability across various applications. Its design supports compatibility with multiple fluids such as water, air, and oil, making it versatile for different operational settings.

With a voltage capacity of up to 600 volts, this pressure switch is factory calibrated for both trip and reset options, assuring precise functionality directly out of the box. The maximum operating pressure it can handle is 175 psi, while it can also withstand occasional surges reaching up to 190 psi. The adjustable differential is set at 1 psi, allowing for fine-tuning of operational parameters.

The setpoint for this unit can be adjusted anywhere from 30 inHg vac to 45 psi, giving users flexibility in application requirements. Installation of the 836-C4E is simplified by its 1/2 inch NPTF internal process connection. Protection is provided by an aluminum enclosure that meets NEMA standards 4, 7, 9, and 13, safeguarding the unit in different environmental situations.

In terms of electrical specifications, the pressure switch is arranged with 2 SPST-NC contacts rated for up to 5 Amps at 240 V and 3 Amps at 600 V for non-inductive loads. It can handle AC voltages up to 125 VA from 24V to 600V and DC ratings of 57.5 VA at 115-230V, with a minimum differential around two times. This unit does not feature a pilot light, focusing on effective pressure monitoring without additional signals.
