Littelfuse Selco G Line Catalogue

Product catalog summary

Overview: The document provides detailed information about SELCO's G-Line Generator Protection Relays, designed primarily for land-based applications. These relays offer cost-effective solutions with advanced features not commonly found in competing products.

Specifications: The relays cover a range of functionalities including overcurrent, undervoltage, overvoltage, underfrequency, overfrequency, and power direction (reverse or forward). They are adaptable with adjustable trip levels, time delays, and hysteresis. The relays are housed in a flame-retardant DIN rail enclosure and support a wide voltage range (63 to 690V AC).

Installation: The relays are designed for easy installation, either on a DIN rail or with screws. They are compact and match the design of the SELCO T-Line product range.

Configuration: Configuration is user-friendly with adjustment dials and a preset push button for setting reference values. Advanced configuration can be done via PC using an optional programming kit (G0100), allowing for customization of relay functions and scales.

Indications and Relays: LED indicators on the front plate show the status of the relay, including power, pick-up, and trip states. The relays have separate contacts for pick-up and trip functions.

Advanced Features: The relays offer optional PC-based configuration, allowing for greater flexibility and customization. They also support external reset with a latch function.

Design and Functionality: G-Line relays are single-function units, with one variant covering all voltages. They include features like level preset functions and optional latching.

Technical Specifications: The document provides detailed technical specifications for various relay models, including current, frequency, power, and voltage relays. Specifications cover supply voltage, input voltage, frequency, trip levels, hysteresis, delay, relay ratings, reset options, accuracy, repeatability, and operating conditions.

Global Presence: SELCO has a worldwide presence with subsidiaries and representations in numerous countries, ensuring global availability and support.

SELCO G-Line for Land-based Applications SELCO’s new G-Line Generator Protection Relays are mainly intended for use in land-based applications. The G-Line range of relays provides an efficient solution in applications where cost of materials is the main issue. Despite a low cost, the G-Line relays still provide a number of ground-breaking features not presently offered by the competing relays. The SELCO G-Line Generator Protection Relays are easy to install. The relays are housed in a compact enclosure for DIN rail mounting or fixation by two ordinary screws. The design matches that of the well...
