Description
Features
- Engineered for a precise mechanical fit, this Type L variable-depth mechanism integrates seamlessly with all 2-pole or 3-pole Square DTM PowerPactTM H-frame and J-frame molded case circuit breakers, as well as CompactTM NSF devices. This dedicated compatibility ensures a flawless physical interface, allowing industrial panel builders to standardize their disconnect mechanisms across a broad range of 600V AC distribution systems without needing multiple niche adapters.
- Meeting rigid NEMA 1, 3R, and 12 sealing requirements when properly paired with an operating handle, this all-metal mechanism prevents the ingress of falling dirt, circulating dust, lint, and external water spray. It protects the core breaker link from premature oxidation and binding, making it highly reliable for washdown zones, processing floors, and outdoor utility installations.
- This safety-focused mechanism features a robust internal lockout system that can be securely padlocked in the "Off" position when the enclosure door is completely open. When combined with a compatible 3-inch or 6-inch exterior rotary handle, it accepts up to three individual padlocks simultaneously keeping the breaker isolated and mechanically locking the door shut to prevent unauthorized entry during critical lockout-tagout (LOTO) maintenance procedures.
- eaturing an intelligent internal link that maintains a distinct mechanical posture when a fault occurs, this mechanism mirrors the exact status of the enclosed breaker. It provides external operators with immediate visual confirmation of a trip event, letting electrical technicians spot safety faults instantly before opening the panel door, accelerating diagnostic testing and reducing worker exposure to potential arc-flash hazards.
