EATON NZM4‑XTVD‑NA Door Coupling Rotary Handle (286644)
Product Overview
The EATON NZM4‑XTVD‑NA (Part No. 286644) is a heavy‑duty, door‑mounted rotary operating assembly engineered for direct mechanical coupling with EATON Moeller NZM4‑series molded‑case circuit breakers (MCCBs). It provides safe, external ON/OFF and manual reset control of the breaker from the exterior of an electrical enclosure, eliminating the need to open the cabinet for routine operation. This unit features a robust mechanical linkage and integrated safety interlocking, ensuring the breaker can only be actuated when the enclosure door is fully closed. Designed for high‑power industrial applications, it delivers reliable performance in power distribution systems, motor control centers, switchgear assemblies, and heavy machinery control panels, meeting stringent safety and durability requirements.
Main Functions
- External Breaker Actuation: Enables ON, OFF, and manual reset operations of NZM4‑series MCCBs from outside the enclosure, preventing exposure to live components.
- Door‑Interlocked Safety: Integrates a mechanical interlock that blocks handle operation unless the cabinet door is securely closed, complying with industrial safety standards.
- Precise Mechanical Coupling: Provides a rigid, direct shaft connection to the breaker’s operating mechanism for consistent, responsive actuation and positive position feedback.
- Visual Status Indication: Clearly displays the breaker’s operating state (ON/OFF/TRIPPED) via the rotary handle’s position for quick system monitoring.
- Heavy‑Duty Compatibility: Optimized for NZM4‑series breakers, supporting high‑current industrial power distribution applications.
- Retrofit & New Installation: Suitable for both new panel builds and retrofitting existing enclosures with NZM4‑series MCCBs.
