Feature: High surge capability with 100 kA per phase provides robust transient protection. Business impact: Protects critical loads and reduces nuisance tripping, extending equipment life and improving uptime in manufacturing environments. Application: Ideal for 3-phase delta systems powering switchgear with remote display. Feature: 320 L-G and 320 L-L voltage ratings with 240 delta (3W+G) configuration ensures compatibility with standard industrial feeders. Business impact: Simplifies system design while meeting phase-to-phase and phase-to-ground limits for compliant installations. Application: Suitable for distribution panels and motor control centers requiring reliable protection at 50/60 Hz. Feature: EMI/RFI filtering delivering up to 50 dB attenuation from 10 kHz to 100 MHz. Business impact: Reduces electrical noise that can affect sensitive control electronics and communications networks. Application: Critical in automated lines with PLCs and servo drives. Feature: Audible alarm with silence button and Form C relay contact enables clear fault signaling and remote signaling integration. Business impact: Improves maintenance planning and reduces unplanned outages. Application: Useful where remote monitoring and alarms are tied to plant SCADA or BMS. Feature: Internal integrated mounting and compact footprint (9.5 in L × 5.4 in W × 3.45 in H; ~3.5 lb). Business impact: Simplifies installation within crowded switchgear enclosures and reduces field wiring complexity. Application: OEM assemblies and retrofit projects where space is at a premium.

FAQs
Consider mounting location inside the enclosure to accommodate its internal integrated design. Verify the 9.5 in length, 5.4 in width, and 3.45 in height fit within your panel and that there is adequate space for wiring and the remote display interface. Ensure 50/60 Hz compatibility and proper grounding to maximize protection.
Key specs include 100 kA per phase surge capability, 240 V delta (3W+G) rating, 320 V line-to-ground and line-to-line, 200 kAIC short-circuit rating, 50/60 Hz frequency range, and 20 kA nominal discharge current. These values ensure robust transient protection for industrial switchgear and connected loads.
Yes. The SPD100240D3B is designed for use with switchgear featuring a remote display and comes with a standard feature package including a surge counter for monitoring. This compatibility simplifies commissioning and enables remote status indication for maintenance teams.
