This OptiFuse MRCBP-24-N-50A is a manual reset circuit breaker suitable for 24VDC applications. It features a robust PBT body and conforms to American National Standard SAE J553.
The circuit breaker is rated for a maximum voltage of 24VDC and a current rating of 50A. It provides overcurrent protection with specific trip times at different load percentages: it opens in over 30 minutes at 100% load, in less than 30 minutes at 135% load, and in less than 1 minute at 200% load.
Operating temperature ranges from -10°F to 150°F, with storage temperatures between -20°F and 200°F. The terminals include a copper plate battery terminal (0.58”) and a zinc plate auxiliary terminal (0.66”).
Warnings indicate that operation beyond specified maximum ratings or improper use may result in damage, electrical arcing, or flame. This device is intended for occasional overcurrent protection, not for repeated overcurrent conditions or prolonged tripping. Avoid contact with chemical solvents, as prolonged contact can damage performance.
