It uses zero-voltage switching, making it a clean fit for resistive heater banks and other loads where inrush suppression matters. Carrying CE, CSA, and UL marks per IEC 60950-1 and IEC 62314, it is panel-mounted with screw terminals and sealed to IP20. The green LED on the input side confirms control power status at a glance.","metaTitle":"Schneider SSP3A250B7 Harmony SSP solid-state relay, 50 A, 3-phase","metaDescription":"Schneider SSP3A250B7 Harmony SSP solid-state relay: 50 A switching current, 48-530 V AC output, 3-phase, zero-voltage switching, IP20, CE/UL/CSA certified.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":[],"specifications":{"Depth":"1.4 in (35.4 mm)","Width":"4.0 in (101.3 mm)","Height":"3.1 in (79.7 mm)","Marking":"CE","Category":"US10CP222375","Standards":"IEC 61000 IEC 60950-1 IEC 62314","Test Button":"Without test button","Load current":"0.1...50 A","Input current":"15...20 mA","LED indicator":"LED, green input","Response time":"20 ms (turn-on) 30 ms (turn-off)","Surge current":"715 A 20 ms 750 A 16.6 ms 150 A 1 s","Output voltage":"48...530 V AC","lifecycle_stage":"current","Flame retardance":"V0 conforming to UL 94","Mounting Support":"Panel","Number of phases":"3 phase","Pollution degree":"2","Range of Product":"Harmony Solid State Relays","Device short name":"SSP","Tightening torque":"0.9...1.1 N.m for input 1.7...2.2 N.m for output","Line Rated Current":"50 A","Thermal resistance":"0.12 °C/W","Device presentation":"Complete product","Dielectric strength":"4 kV AC for input/output 4 kV AC for input or output to case","Maximum capacitance":"8 pF for input/output","Maximum voltage drop":"= 1000 MOhm at 500 V DC","Overvoltage category":"III","Nbr. of units in pkg.":"1","Output switching mode":"Zero voltage switching","Transient overvoltage":"1200 V","Maximum I2t for fusing":"2520 A².s for 10 ms at 50 Hz 2320 A².s for 8.3 ms at 60 Hz","Connections - terminals":"Screw terminals 1 x 0.2...1 x 2.5 mm², AWG 24...AWG 14) input Screw terminals 1 x 1.5...1 x 10 mm², AWG 16...AWG 8) output","IP degree of protection":"IP20","Maximum leakage current":"3 mA off-state","Solid state output type":"Zero voltage switching","Maximum switching voltage":"2 V AC turn-off","Minimum switching voltage":"18 V AC turn-on","Product or Component Type":"Solid state relay up to 50 A","[Uc] control circuit voltage":"18...36 V AC","Ambient Air Temperature for Storage":"-40...257 °F (-40...125 °C)","Ambient Air Temperature for Operation":"-40...176 °F (-40...80 °C)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$95.25 – $237.09","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/d0cdcd458b9c177ce5253b77ef5b7e59.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/SSP3A250B7/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/SSP3A250B7","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/SSP3A250B7 when reusing this data.
