English Product Introduction
The CDM6S-800M/3340 500A plug-in type rear-connected molded case circuit protection device features a thermomagnetic trip mechanism for reliable operation in 50/60Hz AC systems up to 690V. With compact dimensions (75mm width for 3-pole), it adopts plug-in rear connection technology for easy maintenance and space-saving installation. The unit incorporates advanced arc control technology with built-in arc chutes and zero arc distance design, ensuring safe operation during fault conditions. Its 500A current rating suits high-capacity power distribution networks, while multiple mounting orientations provide layout flexibility. 3811
Technical Specifications
This protection device achieves 5ms switching speed through a four-bar linkage mechanism with spring energy storage, offering 20,000 mechanical operations. The triple protection system combines thermal overload, short-time delay and instantaneous short-circuit protection functions. Model 3340 includes shunt trip with auxiliary contacts for remote control and status monitoring. With 70kA breaking capacity at 400V AC, the product ensures system reliability. The modular design allows optional rotary handle for front-panel operation, while rear-connected plug-in terminals accept 16-240mm² conductors. 1710
Structural Features
The UL94 V-0 rated housing provides flame resistance and durability. Silver-alloy contacts minimize energy loss, while the visible trip indicator displays ON/OFF/TRIPPED status. The B-type neutral pole (simultaneous switching with phases) meets building electrical safety standards. Insertion slots with guide rails enable tool-free installation, and the integrated arc chamber contains plasma effectively. The product s unified design allows horizontal, vertical or flat mounting in switchboards. 6911
Application Scenarios
Ideal for main/distribution panels in factories, commercial complexes and infrastructure projects, this device protects critical loads like chillers and production equipment. The plug-in design facilitates quick replacement without power interruption. For fire protection circuits, optional overload alarm without trip function maintains power supply continuity. Compatibility with global busbar systems makes it suitable for multinational equipment integration. 5810
