The OptiFuse MRCBP-H-10A is a single-pole, manual reset circuit breaker designed for reliable circuit protection. It has a current rating of 10 Amps and a maximum voltage rating of 32 VDC.
The breaker is constructed with a UL94V-0 rated thermoplastic body and features copper plate battery terminals and zinc plate auxiliary terminals. It is designed to meet SAE J1171 standards for ignition protection and has an IP63 ingress protection rating, making it suitable for harsh environments.
Key electrical specifications include a 4 times rated current interrupting rating and specific trip curves defined at 25°C/77°F. The operating temperature range is from -10°C to 60°C. Mounting is via chassis mount with specified torque values for studs and mounting points.
This circuit breaker is ideal for applications requiring robust overcurrent protection, particularly in automotive and marine environments where ignition protection and environmental resistance are critical.
