9 Channel 12v DC 18A High-Power PTC Fuse-Free Power Box, max 2A/channel, UL-Listed, AC110-220V, 3yr

This 12-volt DC 9-channel Non-Fuse Breaker Power Supply Box is designed specifically for power-hungry Infrared CCTV Cameras. A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damaged caused by overload or short circuits. Its basic function is to detect a faulty connection, and by interrupting continuity, to immediately discontinue electrical flow. Unlike a fuse, which operates once and then has to be replaced, a circuit breaker can be reset to resume normal operation.
