The CTB-B-B-15 is a single pole, rocker actuated thermal circuit breaker designed to protect equipment from overcurrent conditions. This compact breaker is rated for 15 amps at 125VAC, 250VAC, 125/250VAC, or 50VDC maximum, with an interrupting capacity of 1,000 AIC. It features simple snap-in mounting into a 16mm round double D panel cutout and accommodates panel thicknesses from 0.032 inches to 0.110 inches. The breaker incorporates thermal protection with time-delay characteristics, holding 100% of rated current indefinitely while tripping at 135% of rated current within 1 hour, and at higher overload levels with progressively shorter trip times. Common applications include household appliances, power strips and supplies, marine equipment, audio-visual equipment, medical devices, and exercise equipment.
