Designed & manufactured in Eau Claire, WI, U.S.A.
For applications up to 40 Amps and 350ºF these single shot switches act a a high temperature limit switch in applications from food and beverage, to heating and industrial applications.
Our 3/4″ Single Shot Snap Disc Thermostats are created with bi-metal discs that react to temperature changes and ‘snap’ causing the circuit to OPEN. These one shot thermostats act as a high limit temperature switch that won’t automatically reset. The 2541 Series are perfect for high amperage, one time use, safety limit switches.
Features
- Variety of custom capabilities, such as terminal options, brackets, pipe and tube mounts, over-molding and epoxy sealing, and temperature specifications, to meet needs of original equipment manufacturers.
- The snap-action of the bi-metal disc provides high-speed contact separation resulting in excellent life cycle characteristics at electrical loads up to 40 amps at 240 VAC.
- Welded construction for integrity of current-carrying components.
- Widest fixed temperature setpoints and differentials available on the market.
- Tightest temperature tolerances available in a mechanically design thermostat switch.
- Enclosed or Exposed discs available. Exposed discs allow the switch to react faster to temperature change, an exposed bimetal disc or an optional matte finish disc may be specified. The enclosed disc construction provides greater protection than the exposed disc construction, keeping airborne contaminants such as dirt and dust from entering the control. It also protects the bimetal disc from possible physical damage during assembly and in the final application.
- For added flexibility, the orientation of the terminals with respect to the mounting bracket can be specified in 45 angular degree increments.
- Terminals 90° to mounting holes (standard)
- Terminals 45° clockwise to mounting holes
- Terminals 45° counterclockwise to mounting holes
- The bimetallic disc is thermally and electrically insulated from the power circuit, eliminating self-heating effects.
- Only the temperature of the controlled equipment causes the switch to actuate.
- Switch operation is rapid and positive due to the characteristics of the bimetallic disc.
- Contact chattering is virtually eliminated, as is false cycling and sparking.
- Fastest lead times on the market
- Made in the U.S.A.
