Description
Features
- Featuring a precise 0.5 Amp continuous thermal-magnetic rating, this miniature circuit breaker (MCB) is purpose-built to isolate and protect low-power components. It prevents catastrophic overcurrent damage in delicate instruments, PLC input/output modules, and control transformers, acting as a highly responsive safety line where larger breakers would fail to trip.
- Designed with a standard C tripping curve, the breaker safely absorbs moderate, momentary current spikes between 7 to 10 times its rated current (8.5 times I_n ± 20%). This localized delay allows control circuits, small solenoids, and fans to start up naturally while still providing immediate magnetic trip protection during legitimate short-circuit faults
- Boasting an Ampere Interrupting Rating (AIR) of up to 14kA at 240V AC under UL 489 standards, this robust branch circuit breaker safely suppresses massive electrical faults. It ensures that catastrophic energy surges are contained instantly within the modular housing, protecting downstream electronic controls and maintenance personnel from arc-flash hazards.
- Engineered to operate seamlessly across a broad spectrum of power sources, this 1-pole breaker handles voltages up to 277V AC or 60V DC. This dual-medium adaptability makes it perfect for complex modern panels that utilize standard AC utility power alongside low-voltage DC control loops, solar strings, or battery backup feeds.
