The Wahl Breaker WB140 overheat indicator is designed to warn of possible component failure or overheating of circuit breakers, motors, and electrical equipment. The product provides a visual indication of when a breaker or other device requires attention. It continuously monitors 24/7, with no interruption due to power failure or battery exhaustion. The self-adhesive temperature recording label has a silver-gray indicator that turns permanently black in less than one second. The indicator is accurate to within ±1 percent, traceable to NIST. Each package contains 30 temperature-sensitive labels and one inspection log to record every formal visit to inspect labels for color changes.
