Product name: Surge Protection Device SPG940KA3P AC SPD Model: GSP940KA3P AC SPD Type: Circuit breaker style surge protection device Smart device: No Customized: Yes Overview A three pole surge protection device designed for AC distribution systems. Provides transient overvoltage protection with a rated discharge capability up to 40KA. Designed for integration into 3P distribution panels and protective circuits for equipment fed from 220 380 volt systems. Key specifications Poles: 3P Model: GSP940KA3P AC SPD Rated system voltage: 220/380V Size rating: 3P AC400V 40KA Maximum continuous operating AC voltage options: AC275V, AC385V, AC400V, AC440V Discharge current range: 20 to 40KA Type: Circuit breaker style surge protector Smart functions: none : available Why you need this product Protects downstream equipment from transient voltage spikes and lightning induced surges by diverting surge current away from sensitive circuits. Reduces downtime and equipment damage in distribution panels, control cabinets, and power feeders. Offers selectable maximum continuous operating voltage options so you can match the SPD to the system voltage for reliable operation. How it solves problems and what makes it stand out transient handling: Rated discharge current up to 40KA handles heavy surge events that can otherwise damage electrical and electronic loads. Three pole coverage: Single unit provides coordinated protection for all three phases in three phase systems, simplifying installation in 3P panels. Configurable maximum continuous operating voltage options: Allows selection appropriate to specific grid conditions and coordination requirements. Circuit breaker style form factor: Integrates into protection schemes where a breaker type device is preferred or required. Compatibility and performance notes Intended for use on AC distribution systems with nominal voltages around 220 380V and higher transient tolerance up to AC400V. Choose the appropriate maximum continuous operating AC voltage option (AC275V, AC385V, AC400V, or AC440V) to suit system voltage and coordination needs. Not a networked or smart device. Designed for conventional electrical installations. Typical applications Residential and small commercial distribution panels to protect household or office electrical equipment from external and internal surges. Commercial buildings and retail fitouts where three phase power feeds critical loads such as lighting, HVAC, and IT equipment. Industrial control panels and motor control centers where surge protection reduces risk to drives, PLCs, and sensitive instrumentation. Installation and selection guidance Install in the main distribution board or at distribution branch points to provide primary protection for downstream circuits. Verify system nominal voltage and select the MCCOV option that matches or slightly exceeds continuous operating voltage for correct operation. Ensure coordination with upstream and downstream protective devices when integrating into existing protection schemes. options are available to match specific system voltage requirements or installation preferences. Confirm model GSP940KA3P AC SPD and required MCCOV option when ordering. This surge protection device provides three pole surge suppression with discharge capability and multiple MCCOV options for compatibility with common AC distribution systems.
