The Littelfuse CMBA-083-NNFNN-B-A is a single-pole thermal circuit breaker designed for overcurrent protection in electrical circuits. It is rated for 8 amps of continuous current at 250 volts AC or DC, making it suitable for a variety of low-to-medium power applications.
This breaker uses a thermal mechanism that responds to sustained overcurrent conditions by opening the circuit. It features an automatic reset actuator type, meaning the breaker will automatically close once the overcurrent condition clears and the internal element cools, restoring power without manual intervention.
The device is designed for panel mount installation, allowing for secure integration into equipment enclosures. It has no illumination, providing a simple and reliable form factor for basic circuit protection needs.
The current rating is 8A.
The voltage rating is 250V.
It is a thermal circuit breaker.
It has 1 pole.
The actuator type is automatic reset.
The mounting type is panel mount.
