Snap Action, Limit Switches, is an important type of electromechanical switch, a device that can sense the presence or absence of something in its vicinity. 831613C3.FB is an example of such an instrument, designed specifically for general industrial applications where low voltage and/or load power is needed. It features a hermetically sealed, field adjustable snap action switch, capable of switching currents up to 480 Vac, 750Vdc. This article explores the application field and potential of 831613C3.FB, as well as its working mechanism.

831613C3.FB can be used in a variety of industrial applications, ranging from pressure sensing and protection or industrial automation to electric motor control. The switch is especially suitable for applications in which high contact strength and long electrical life are required, such as in HVAC systems, pumps, fans, heaters air conditioners, and components for safety and interlock protection. It offers a maximum voltage rating of up to 480 Vac, 750Vdc, and a current carrying capability of 10A.

831613C3.FB is based on a snap-action mechanism and a precision contact system, which offers a low contact resistance, low current leakage, and reliable operation and insulation. The unit has a hermetically sealed enclosures to protect against ingress, and offers excellent dielectric strength and resistance to shock and vibration. It can also be used with a variety of actuators and accessories to give it further flexibility and usability. For example, a rod actuator can be used to increase sensitivity.

The switch features a field adjustable spring for precise snap-action and operator adjustable limit stops for control. The unit integrates four contact systems: single-pole double-throw, double-pole single-throw, normally open, and normally closed. These contacts remain open until an operator trip force is applied, at which point the contacts close and the switch is activated. It also features a plunger system for manual reset, allowing it to be set in either direction manually.

In terms of construction and design, 831613C3.FB is designed for rigid mounting and features a 14-pin terminal lug for easy connection. The switch has a positive break action, which helps prevent accidental switching at temperatures ranging from -25°C to +85°C. It also has a sealed housing to protect against dust, water and other environmental hazards. The unit is UL and CSA approved.

To summarize, 831613C3.FB is an ideal choice for a variety of industrial applications requiring long life and reliability. Its snap-action mechanism and precision contact system provide low contact resistance and reliable operation. The unit’s hermetically sealed enclosure helps to promote safe operation in hazardous environments, and a field adjustable spring allows for precise snap-action and operator adjustable limit stops for control. With its 14-pin terminal lug and a UL and CSA approval, 831613C3.FB is a highly versatile, safe, and reliable solution for a variety of industrial applications.
