Special features
Standard with surge counter
High-energy surge protection is delivered by a 400 kA per phase rating in a single-module form. This capability dramatically reduces the risk of costly transient damage in demanding environments such as data centers, machine controls, and panelboards. In practice, engineers specify SPM400240D3V to protect motors, drives, PLCs, and sensitive electronics against external faults. System compatibility is ensured with a 240 Delta (3W+G) configuration, enabling straightforward integration into existing 3-wire + ground networks and minimizing rewiring. The NEMA 4X enclosure with an internal circuit breaker provides weatherproof and washdown-ready protection, supporting outdoor panels and harsh environments while simplifying service access. The built-in surge counter offers diagnostics for proactive maintenance, while RoHS and safety certifications support regulatory compliance and supplier confidence. With these features, facilities realize reduced downtime, longer asset life, and lower lifecycle costs.
