Square D™ Surgelogic™ SDSA1175 SPDs offer a simple means to bring down initial surges to manageable levels and can offer additional value in a cascaded SPD system. Their compact design allows surge suppression to be installed adjacent to power panels or directly on sensitive equipment.

Key Features:

• Type 1 rated devices provide the flexibility to be used with or without an Overcurrent Protection Device (OCPD)
LED indicated operational status
• Short circuit current rating 25kA
• Suitable for indoor and outdoor application (NEMA Type 4X rated)
• Convenient back-nipple mounting
• SDSA1175 are designed and listed for indoor or outdoor installation and surge suppression for single-phase three-wire 120/240 Vac or two-wire 120 Vac 60 Hz electrical services
• Two SDSA1175 SPDs can be installed to provide suppression for 208Y/120 Vac three-phase four-wire services
• Field-proven MOV design provides response time less than 50 nanoseconds and provides lower clamping voltage than traditional gas tube arresters
• Coordinated Fuse Technology

Benefits:

• Provide surge suppression to vulnerable equipment powered from weather exposed panels
• Transient suppression is located at the most efficient connection point
• Allows for flexibility in installation locations
• Allows immediate indication if suppressor requires replacement
• Provide premium surge suppression while managing thermal effects from MOV end of life

Applications:

• OEM
• Low Voltage Products & Systems
• Building Automation & Control
• Industrial Automation & Control
• Critical Power, Cooling & Racks
