Sicherungssockel H1 DR1 400 — backup base for a 1P Sicherungstrennschalter with NT2 RS33 socket. Forms the H1 base in the DR1 400 family. A 3P variant for three-phase installations is available as H1(DR1)400/3P. Why you need it Provides a reliable, standard isolation point inside electrical cabinets for safe service and maintenance. Modular upgrade path: start with the 1P Sicherungssockel H1 DR1 400 and expand to three-phase systems using the H1(DR1)400/3P base. Saves panel space with a compact footprint and simplifies mounting in tight control cabinets. Speeds maintenance: dedicated base allows quick replacement or servicing of the 1P Sicherungstrennschalter without rewiring. Key benefits and how it solves problems Secure isolation: ensures a clear, stable disconnect point to protect personnel and equipment during service. Flexibility: compatible with NT2 RS33 socket and the DR1 400 family, enabling consistent installation standards across panels. Serviceability: reduces downtime by allowing rapid swap of the Sicherungstrennschalter on a fixed base. Space-efficient design: fits small panels where larger bases would complicate layout or require redesign. Robust build: engineered for continuous operation and frequent handling during maintenance cycles. Key attributes Function: one-pole (1P) Sicherungstrennschalter base. Compatibility: NT2 RS33 socket; H1 DR1 400 family; upgradable to 3P with H1(DR1)400/3P. Size: compact base suited for panel mounting in confined spaces. Material/build: robust construction designed for continuous use and reliable mechanical stability. Performance: stable isolation, dependable operation under normal industrial conditions. Installation and upgrade notes Mounts directly in standard control panels; designed to simplify wiring and mounting. Upgrade from 1P to 3P installations by swapping to the H1(DR1)400/3P base to cover three-phase feeders without changing the overall system architecture. Applications / use scenarios Control panels for conveyors: provides a safe single-feeder shutdown point for maintenance on conveyor drives and associated controls. Packaging and automation machinery: enables quick replacement of the 1P Sicherungstrennschalter during scheduled maintenance to minimize line stoppage. Distribution cabinets: install as the default 1P isolation base and later upgrade to three-phase protection using the H1(DR1)400/3P when system loads increase. Technical consistency Product name, family and compatibility: Sicherungssockel H1 DR1 400; H1(DR1)400/3P for 3P; NT2 RS33 socket compatibility; base for 1P Sicherungstrennschalter. Ordering tip Specify H1 DR1 400 for single-pole installations and H1(DR1)400/3P when three-pole capability is required.
