FAQs
SPC150240D4P supports external side mounting, simplifying installation in compact panels and retrofit scenarios. With dimensions of 7.5 in L x 8.5 in H x 3.19 in W and a 4 lb weight, it fits typical enclosure footprints while providing quick access for wiring and diagnostics. This arrangement reduces field time and wiring complexity for engineers.
150 kAIC is the interrupt rating, indicating the maximum surge current the device can safely interrupt without damage. For 240V delta systems, this rating translates to robust protection against high-energy transients, minimizing the risk of downstream equipment failure and enabling longer service life of connected loads in demanding environments.
This device is well-suited for industrial control panels, manufacturing lines, and equipment fed from 240V delta systems. Its NEMA 4X enclosure makes it viable for harsh environments, while the Form C relay supports signaling or interlock needs. The combination delivers reliable surge protection for critical machinery and power distribution networks.
The SPC150240D4P is UL 1449 listed and housed in a NEMA 4X enclosure, ensuring compliance with recognized safety standards and suitability for wet, dusty, or corrosive environments. These certifications and ratings help procurement teams justify regulatory readiness and long-term reliability in industrial facilities.
Plan for periodic verification of protection status and wiring integrity during preventive maintenance. With a 10-year warranty and UL 1449 listing, the device is designed for durability, but consider annual visual checks and post-surge inspections following events to confirm continuous operation and trigger timely replacement if performance indicators decline.
