FAQs
The SPD100240D1B is designed for use with 240V delta (3W+G) switchgear that includes remote display capabilities. It installs in an internal integrated mounting arrangement, minimizing enclosure footprint and enabling straightforward retrofits or new builds in industrial control rooms. Ensure mounting within compatible switchgear cabinets and verify space for the 9.5 in length and 5.4 in width.
Key specifications include 100 kA per phase surge current, 200 kAIC short-circuit rating, 320 L-G and 320 L-L MCOV, and a 240 V delta (3W+G) rating. It operates at 50/60 Hz, with a temperature range of -40 to 50 °C. The device weighs 3.5 lb and is built for UL 1449 Listed protection with EMI/RFI filtering up to 50 dB.
By delivering high transient protection and noise filtering, the SPD reduces equipment stress, minimizes nuisance trips, and extends the life of connected equipment. The audible alarm, surge counter, and Form C relay contact enable quick fault diagnosis and integration with monitoring systems, which translates to reduced downtime, lower repair costs, and improved overall uptime.
The device is UL 1449 Listed and UL Listed, ensuring compliance with critical safety standards for surge protection devices. It also aligns with building and electrical safety expectations referenced in IBC 2006, CBC 2007, and UBC Zone 4, supporting safe installation in diverse regulatory environments.
Plan for internal mounting in compatible switchgear with remote display capability. Include the Basic feature package, verify space for the 9.5 in length, 5.4 in width, and 3.45 in height, and ensure environmental limits are met (-40 to 50 °C). Routine checks should monitor the audible alarm status, verify the surge counter, and service the device under the 15-year warranty window.
