Product overview A compact pluggable 2 pole module rated for AC400V, designed for fast response to transient overvoltages and straightforward installation on standard DIN rails. The unit combines discharge capacity with simple visual diagnostics and tool replacement to reduce maintenance time. Key benefits Fast response and discharge capacity: Acts quickly to divert surge energy, helping limit the impact of transient overvoltages on downstream equipment. Pluggable design for fast service: Plugin module simplifies replacement without rewiring, reducing system downtime and maintenance effort. Clear visual status indication: Green window shows normal operation; red window indicates the module is defective and should be replaced. Compact 2P format and DIN rail mounting: Saves space in distribution and control panels and installs easily on standard DIN rails. Improved endoflife reliability: Double thermal disconnection devices provide redundant disconnection behavior, increasing the reliability of module isolation at end of life. Function and compatibility Function: Rapid surge discharge module for AC systems up to 400 volts with two poles. Compatibility: Intended for integration into 2 pole AC distribution circuits and standard DIN rail enclosures where a pluggable surge/discharge solution is required. Form factor: 2P pluggable module sized for DIN rail mounting. Status indication: Simple green and red visual window for quick field checks. Performance and maintenance Fast response time combined with discharge capability supports reliable handling of energy transients. Pluggable construction enables quick swapout of modules without extended panel access or rewiring. Double thermal disconnect elements provide an additional layer of disconnection reliability when the module reaches end of life. Visual window allows maintenance personnel to confirm module condition at a glance and defective units promptly. Typical applications Residential and commercial distribution boards: Install in consumer units and service panels to address transient overvoltages on 2 pole circuits up to 400V. Industrial control cabinets: Protect control electronics and sensitive automation equipment where compact DIN rail modules and fast replacement are needed. Power distribution for equipment racks and local panels: Use in localized panels for machinery, motor drives, or backup power systems to simplify maintenance and monitoring. What to expect in the field Plug in the module on a standard DIN rail, verify the green status window for normal operation, and the module if the window shows red. The unit is sized as a 2P module and rated for AC400V applications. Designed to minimize service time with a pluggable form factor and clear visual indication of endoflife condition.
