Built on Mersens patented TPMOV technology, this thermally protected MOV design eliminates the need for additional upstream overcurrent protection devices. The unit carries UL 1449 4th Edition approval and delivers a nominal discharge current of 20 kA with a short circuit current rating of 200,000 amps. Response time is under 25 nanoseconds. Licensed electricians install this device in commercial and industrial panel applications where reliable surge suppression and minimal footprint are both required.\u003c\/p\u003e\n\u003cp\u003eThe STP480YN07M is suited for 480Y\/277V, 4-pole, 5-wire AC distribution systems operating at 50 or 60 Hz. Its DIN rail mounting profile allows direct installation inside existing enclosures without dedicated panel space. The integrated microswitch indicator provides local visual status confirmation, and the remote indicator option allows status signaling to critical control circuitry, making it appropriate for building automation panels, industrial control cabinets, and similar installations where system uptime monitoring is a priority.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTPMOV technology provides thermally protected MOV operation, removing the need for separate overcurrent protection\u003c\/li\u003e\n  \u003cli\u003eUL 1449 4th Edition listed fail-safe, no-fuse design\u003c\/li\u003e\n  \u003cli\u003eShort circuit current rating of 200,000 amps supports high-fault-current service entrance and feeder applications\u003c\/li\u003e\n  \u003cli\u003eNominal discharge current of 20 kA with response time under 25 nanoseconds\u003c\/li\u003e\n  \u003cli\u003eDIN rail mountable with compact footprint: 4.19 inches long, 2.76 inches wide, 2.81 inches tall\u003c\/li\u003e\n  \u003cli\u003eMicroswitch indicator and remote indicator option for integration with control circuitry\u003c\/li\u003e\n  \u003cli\u003ePluggable module design simplifies field replacement without rewiring the base\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on 480Y\/277V, 4-pole, 5-wire AC distribution systems as a Type 1 surge protective device.
