High energy handling and fast response: SPD100240D3J delivers a 100 kA per phase surge current and a 200 kAIC short-circuit rating. This level of protection minimizes voltage transients that can trip breakers, degrade insulation, or damage motor windings. In MCC applications, that translates to fewer nuisance trips and longer motor life, supporting consistent production. Integrated mounting and the standard feature package, including a surge counter, streamline installation and diagnostics. The internal integrated design reduces panel space requirements and simplifies cable routing, making retrofits in existing motor control centers easier. Compatibility with common MCC enclosures and wiring practices lowers field wiring errors and accelerates commissioning. Audible alarm with silence button and a Form C relay contact provide immediate fault indication without extra hardware. EMI/RFI filtering offers up to 50 dB of noise attenuation from 10 kHz to 100 MHz, improving control signal integrity and reducing EMI-related issues in crowded panels. The surge counter with a rest button enables quick maintenance checks and traceability. Operating parameters align with common MCC power feeds: 50/60 Hz, 240 V delta (3W+G), and 320 L-G/L-L MCOV, ensuring compatibility with standard distribution schemes. This configuration supports reliable protection across voltage variations while enabling straightforward integration with existing protection schemes and motor starters. Rugged construction and long-term reliability are reinforced by a -40 to 50 °C operating range, UL 1449 and UL Listed certifications, and a 15-year warranty. Its compact footprint—9.5 in L × 5.4 in W × 3.45 in H—and a 3.5 lb weight simplify panel layouts and allow scalable MCC protection for growing facilities, reducing lifecycle costs.

FAQs
Install the device with internal mounting inside an appropriate MCC panel, connecting L-L and L-G according to the 240 V delta (3W+G) rating. Ensure 50/60 Hz supply and 320 V MCOV alignment. Use the surge counter for status checks, and connect the Form C relay for remote fault indication. Verify clearance and wiring following OEM guidelines.
Key ratings include 100 kA per phase surge current, 200 kAIC interrupt rating, 20 kA nominal discharge current, and 320 V MCOV (L-G and L-L) with a 240 V delta configuration. The device operates across 50/60 Hz and maintains performance from -40 to 50 °C, making it suitable for harsh industrial environments.
Yes. Designed for MCC protection, SPD100240D3J fits standard panel footprints and supports both new installations and retrofits. Its internal mounting, surge counter, audible alarm, and Form C relay help installers integrate quickly, while EMI/RFI filtering reduces electrical noise in dense automation panels. This makes it a reliable choice for existing facilities expanding MCC protection.
The unit carries UL 1449 certification and UL Listed status, indicating compliance with established safety standards for surge protection devices. This dual UL endorsement supports regulatory compliance and helps simplify procurement for safety-conscious projects in industrial environments.
The built-in surge counter with a rest button enables straightforward maintenance checks and traceability, reducing diagnostic time during servicing. EMI/RFI filtering and reliable protection lower downtime and extend asset life, delivering a favorable total cost of ownership for MCC protection investments and helping justify lifecycle maintenance budgets.
