Product Description

W66 – 30A is a resettable thermal circuit breaker (manual reset) designed to protect circuits against overload and short circuit. Its robust construction, flame-retardant housing, and large screw terminals make it suitable for light industrial and hobby applications: distribution panels for DIY projects, CNC/robotics, AC power supplies, chargers, and DC circuits up to 50 V.

It mounts easily on a panel through the threaded metal bushing; after tripping, the circuit is restored by pressing the button. The LINE and LOAD markings help with correct wiring, and the certifications visible on the label confirm safe use.
