Description
Features
- Engineered as a precision-calibrated heating element, this Square D by Schneider Electric B Series thermal unit constantly monitors the current traveling to your motor windings. In the event of a sustained overload or a locked-rotor condition, the excess current generates proportional thermal energy within the element to safely trip the starter, cutting off power before catastrophic winding insulation breakdown or permanent motor damage can occur.
- Utilizing a dependable, high-accuracy melting alloy sensing method, this thermal unit features a durable one-piece construction with a factory-sealed solder reservoir and an internal mechanical ratchet wheel. When current spikes past safe limits, the internal alloy melts at a precise thermal threshold, instantly releasing the ratchet mechanism to open the control circuit contacts a physics-based approach that completely eliminates the calibration drift common in standard bimetallic alternatives.
