NEW ABB SPAU-330 C1

Description

ABB SPAU-330 C1: Industrial Three-Phase Voltage Protection Relay As a core model of ABB’s field-proven SPACOM relay family, the ABB SPAU-330 C1 is a high-precision, heavy-duty three-phase voltage protection relay, engineered for overvoltage, undervoltage, residual voltage, and phase anomaly supervision in LV/MV power networks. It is the go-to solution for electrical maintenance teams, power integrators, and industrial parts distributors worldwide. Built to IEC 60255 international standards, the ABB SPAU-330 C1 delivers reliable mission-critical performance. Core specifications include 110–250V AC/DC wide auxiliary power compatibility, 50/60Hz rated frequency, support for standard 100V/110V PT secondary inputs, and IP54 front-panel protection rating for control cabinet mounting. This relay integrates a full protection suite: adjustable overvoltage/undervoltage protection, phase sequence failure, phase loss, and phase imbalance protection, with dual setting groups and configurable time delays for diverse grid needs. It features real-time voltage measurement, LED status indicators, fault latching, and high-capacity relay outputs for direct breaker tripping, enabling fast fault isolation to minimize downtime. An optional disturbance recorder module supports fault data export for post-event analysis, with continuous hardware/software self-supervision for enhanced reliabilityABB Group. Widely deployed across utility substation busbars, power plant auxiliary systems, industrial motor control centers, transformer/capacitor bank protection, data centers, and renewable energy grid-tie systems, the ABB SPAU-330 C1 adapts to both solidly earthed and isolated neutral networks. Genuine ABB SPAU-330 C1 units offer unbeatable advantages: OEM-grade build quality for long-term service, -25°C to +70°C wide operating temperature, and strong anti-electromagnetic interference for harsh industrial environments. Its plug-and-play design simplifies installation, cutting maintenance labor and outage time. Fully tested used ABB SPAU-330 C1 units deliver 70%+ cost savings vs. new models, with in-stock availability to avoid long factory lead times, and all pre-owned units undergo rigorous functional, accuracy, and insulation testing to meet original ABB specifications. Whether for new power system construction, legacy relay replacement, or critical spare parts stocking, the ABB SPAU-330 C1 delivers compliant, reliable, cost-effective voltage protection to keep your distribution system running safely and continuously.
