MOCB2-CL-40A Description

Short technical summary and product information.

The OptiFuse MOCB2-CL-40A is an automotive Type II circuit breaker with a modified reset classification and an automatic reset actuator. It is rated for 12 VDC and 40 A, with a single-pole design and a metal body. The circuit breaker meets SAE J553 requirements for automotive circuit protection.

 

The device provides time-delayed overcurrent protection. At 100% of rated current, the open time is greater than 30 minutes; at 135% of rating, it opens in less than 30 minutes; and at 200% of rating, it opens in less than 1 minute. These characteristics allow the breaker to tolerate normal inrush currents while still protecting wiring and loads from sustained overcurrent conditions.

 

The MOCB2-CL-40A is intended for 12 VDC automotive electrical systems. Its fuse clip footprint supports installation in applications where a fuse clip form factor is used. The component is supplied in bulk packaging.

 

This circuit breaker is suitable for overcurrent protection in automotive wiring, auxiliary power distribution, and similar 12 VDC circuits.
