Overview

The Littelfuse ER-600VC is a specialized sensing resistor accessory designed for neutral-to-ground fault detection in industrial systems up to 600 Vac. This accessory is a critical component for the Littelfuse SE-330, SE-325, and SE-330AU series relays, acting as an essential interface to safely reduce hazardous system voltages to levels compatible with these protective relays. Engineered for continuous duty, the ER-600VC features a resistance of 20 kΩ (switch S5 setting) and a maximum continuous current rating of 5 Amperes. Its thermal capabilities allow for continuous operation at 480 Vac and 600 Vac. The ER-600VC is integral to systems requiring accurate ground-fault monitoring, working in conjunction with current transformers (CTs) to provide precise fault detection and system response. It contributes to enhanced personnel safety by isolating high voltages from the relay and improves overall system reliability. The ER-600VC is designed for indoor applications and is available with an optional moisture-proof enclosure for outdoor installations. It is used on systems up to 1 kV (continuous duty). The ground-fault pickup level is 2.5 Amperes. The product is also referred to as PGE-600V. The operating temperature range is -55 to 60°C (-67 to 140°F). Shipping weight is 300 g (0.7 lb).
