Eaton Cutler-Hammer SNT4LP11K Shunt Trip Type LD

Eaton Cutler-Hammer SNT4LP11K is a shunt-trip accessory for L-frame circuit breakers, Type LD. This device provides remote tripping by energizing a shunt-trip coil when a signaling voltage is applied, enabling rapid circuit disconnection from a separate control point. It is specified for 110–240 VAC signaling and is designed to fit Eaton Cutler-Hammer L-frame LD-type breakers, with the SNT4LP11K designation identifying this exact shunt-trip configuration within the product family. By matching the LD-type shunt-trip design, it integrates with the corresponding Eaton equipment to support safety and control applications in electrical panels and protection schemes that require a remote trip function on the associated breaker.
