The OptiFuse CBW58-BL-40A-5X is a single-pole thermal circuit breaker rated for 40A continuous current. It handles 125/250 VAC (50-60 Hz) and 32/50 VDC, with interrupting ratings of 1000A at 125/250 VAC and 300A at 50 VDC. The push-to-reset actuator provides manual reset after a fault, with a 60-second reset time. Time-current characteristics ensure no trip at 100% rated current, trip within 1 hour at 150%, 5-30 seconds at 200%, and 1.5-5 seconds at 300%.
Mounting is panel mount with a black plastic body and tin-plated terminals. The breaker is marine ignition protected to SAE J1171 and UL1500, making it suitable for marine and automotive environments. It operates from -10°C to +60°C and has a dielectric strength of 1500 VAC. This breaker meets cURus and UR safety standards.
