High surge capability is engineered into SPD100240S1J, delivering 100 kA per phase with a 200 kAIC short-circuit rating. This energy absorption keeps transient events from reaching downstream equipment, significantly reducing the risk of motor windings, drives, and contactor failures. In MCC environments, that translates into less unplanned downtime and lower repair costs.Voltage compatibility and safe operation are built around a 120/240 V split single-phase rating with operating voltages of 150 L-N, 150 L-G, 150 N-G and 300 L-L. The business impact is straightforward: simpler wiring, fewer misconfigurations, and faster panel upgrades in factories, data centers, and process lines. It also supports easy integration with existing MCC infrastructure.EMI/RFI filtering delivers up to 50 dB of noise attenuation from 10 kHz to 100 MHz, improving signal integrity for drives, PLCs, and sensors. The result is more predictable control behavior and longer component life in automation lines. This feature is particularly valuable in environments with heavy motor loads and variable-speed drives.Audible alarm with a silence button and a Form C relay contact provides immediate fault notification and simple integration with plant-wide monitoring. Operators gain visibility without opening panels, while the relay enables remote signaling to BMS or SCADA. This combination reduces mean time to acknowledge and repair surges affecting critical equipment.Internal integrated mounting and a basic feature package streamline installation by reducing external components and wiring. The device ships ready to install in motor control centers, decreasing panel depth and complexity. For refurbishments, its compact footprint and weight of 3.5 lb fit within tight MCC enclosures while maintaining accessibility for maintenance.Warranty and durability reinforce lifecycle value: a 15-year warranty supported by UL 1449 Listed certification underpins long-term protection. The device operates from -40 to 50 °C and is designed for rugged industrial environments, ensuring dependable protection across shifts and seasons.

FAQs
SPD100240S1J is designed for straightforward installation inside motor control centers. Its internal mounting and compact 9.5 x 5.4 x 3.45 inch footprint reduce panel depth and wiring. For best results, place the unit close to the MCC feeder, ensure adequate clearance for heat dissipation, and verify compatibility with the panel's conductor sizes and labeling requirements before commissioning.
The device is rated for 100 kA per phase surge current with a 200 kAIC short-circuit rating, providing substantial protection against energizing transients. In practice, this reduces the likelihood of upstream equipment damage, extends motor life, and minimizes unplanned downtime in facilities with heavy startup loads or frequent switching.
Yes. SPD100240S1J operates on a 120/240 V split single-phase basis and supports voltage combinations of 150 L-N, 150 L-G, 150 N-G, and 300 L-L. This makes it suitable for standard MCC feeders and common industrial panels, simplifying wiring and reducing configuration errors during installation or upgrades.
SPD100240S1J carries UL 1449 Listed certification, underscoring safety and performance under surge conditions. It also meets IBC 2006, CBC 2007, and UBC Zone 4 requirements, providing building code compliance for industrial facilities and ensuring reliability in harsh environments where code conformity matters.
The device contributes to a favorable return on investment by reducing unplanned downtime, extending motor and drive life, and lowering maintenance labor. Features such as a surge counter with rest button support proactive maintenance, while a 15-year warranty reduces lifecycle risk and total cost of ownership for motor control centers.
