Surge Protector and Voltage Protection Relay 63A Adjustable Over Under 120V DIN Rail Mount

Surge Protector and Voltage Protection Relay 63A Adjustable Over Under 120V DIN Rail Mount Description

Mini surge protective device SVP9121, size 63A, for under and over voltage protection in 120Vac systems. Designed for DIN rail installation, this compact module offers adjustable protection thresholds and a clear single LED status indicator. Key benefits Protects equipment from sustained under voltage and over voltage conditions by disconnecting loads when thresholds are exceeded, reducing the risk of damage and unplanned downtime. Adjustable protection values let you set overvoltage and undervoltage cutoffs to match the requirements of different installations and sensitive devices. Compact mini form factor and DIN rail mounting save panel space and simplify integration into distribution boards and control cabinets. Simple visual status via single LED makes system checks fast and easy for maintenance staff. What makes it stand out Model SVP9121 tailored for 120Vac, 50/60Hz systems with configurable voltage limits. Twopole design for reliable control of singlephase circuits. Available load ratings for panel matching: 40A, 63A, and 80A while the unit shown is size 63A. No limit current protection included, so overcurrent protection should be provided separately as required by the installation. Key specifications Model number: SVP9121 Type: Mini surge protective device Functions: Undervoltage protection and overvoltage protection Overvoltage protection range: 130V to 150V (adjustable) Undervoltage protection range: 80V to 100V (adjustable) Protection value: Adjustable Limit current protection: No Power supply: 120Vac, 50/60Hz Display: Single LED indicator Load ratings: 40A, 63A, 80A Poles: 2 poles Dimensions: 36 x 65 x 85 mm Installation: DIN rail Typical applications Residential or small commercial distribution panels where compact over and under voltage protection is required for HVAC, refrigeration, or motor loads. Industrial control cabinets protecting PLCs, contactors, and control circuits from sustained voltage excursions in singlephase 120Vac systems. Backup power and generator systems to prevent sensitive loads from operating outside safe voltage ranges during source transitions. Installation notes Mount on a standard DIN rail. Ensure overcurrent protection is provided separately since the device does not include limit current protection. Adjust voltage thresholds to match the protected equipment requirements and verify operation using the LED status indicator.
