United Electric B402-120 Temp Switch
The United Electric B402-120 is a heavy-duty dual-switch temperature control designed for industrial process monitoring and threshold protection. Part of the 400 Series, this immersion stem temperature switch features two SPDT snap-acting switches that can be independently adjusted across the 0°F to 225°F range, allowing for versatile dual-stage control such as high/low limit alarms or simultaneous alarm and shutdown functions. Built for demanding environments, the assembly is housed in an epoxy-coated diecast aluminum NEMA 4X enclosure, providing superior resistance to corrosion and moisture. The 9/16" nickel-plated brass stem ensures rapid thermal response while maintaining structural integrity in pressurized systems. For precise field calibration, the unit includes an internal adjustment with a reference dial, enabling technicians to set trip points with a repeatability of ±2% of the full-scale range. This electromechanical switch provides reliable locally-mounted control for pumps, turbines, and heat exchangers without requiring external power for operation.
Key Benefits:- Dual SPDT Outputs: Provides multi-stage signaling for alarm and emergency shutdown through two independent 15A switches.
- Harsh Environment Protection: The NEMA 4X rated housing is gasketed and epoxy-coated to withstand washdowns and corrosive atmospheres.
- Wide Adjustable Range: Monitors process temperatures from 0 to 225°F with a maximum survival temperature of 275°F.
- Simplified Calibration: Features an internal reference dial for accurate setpoint adjustments without specialized tools.
- Industrial Specifications: Features a 3/4" NPT electrical connection and a nickel-plated brass immersion stem for compatible fluid media.
- Can the two switches be set to different temperatures? Yes, the B402-120 allows both switches to be separated by up to 100% of the range for stagged control.
- What is the maximum electrical load for the contacts? The internal snap-acting switches are rated for 15 Amps at 125/250/480 VAC.
- How do I adjust the setpoints? Adjustments are made internally via the calibrated reference dial; simply remove the cover to access the adjustment mechanism.
