Protection relays and transformers

Product catalog summary

Introduction
This document provides an overview of protection relays and transformers, focusing on their applications, specifications, and selection criteria. It highlights the range of products offered by CIRCUTOR, designed to meet various client needs and comply with relevant specifications.

Product Selection Table
The document includes a product selection table categorizing equipment based on applications such as beacon control equipment, harmonics relays, current relays, and transformer overload protection relays.

Control Relays
Beacon Control Relays (TB and TB-3): These relays supervise and control beacon circuits on telephony transmission towers, managing ballast consumption and photocell inputs. The TB model handles dual circuits, while the TB-3 model is for single circuits.
Voltage Detector Control Relay (RV-M / RV-T / RV-TS): These relays protect against disruptions in the neutral connection by measuring voltages between phases, applicable to both single-phase and three-phase installations.

Protection Transformers
Types and Features: The document describes TRM (Measurement Transformers) and TRP (Protection Transformers), both encapsulated in resin for robustness and core manipulation prevention. Key features include primary and secondary current specifications, frequency, insulation voltage, and thermal class.
Selection Criteria: Choosing the right transformer involves understanding the application, environmental conditions, line features, and associated instrument specifications. The transformer's power is crucial to meet line losses and equipment consumption.

Standards and Compliance
The products comply with standards such as IEC 60044-1 and UNE-EN 60044-1, ensuring reliability and safety in their applications.

Conclusion
CIRCUTOR offers a comprehensive range of protection relays and transformers designed for various applications, ensuring robust performance and compliance with industry standards.

Voltage Monitoring Relays
These relays detect incorrect phase sequence, phase loss, voltage surges, and drops, suitable for industrial and modular cabinets using true root mean square measurement. Protection against voltage surges triggers at voltages higher than 265 V, while voltage drops trigger at less than 160 V. Phase sequence errors have a fixed trigger time of 1 s, except for the RV-TS type. External input activation has a trigger time of ≤10 ms, with indication LEDs for power supply and voltage error.

Control Relays
Applicable for single-phase and three-phase installations with different types and codes for each configuration. Specifications include a power supply circuit of 230 Vac, frequency of 50 Hz, and various testing voltages. Build features include DIN rail fixing, dimensions of 4 modules, weight of 250 g, and an operating temperature range of 0 to +50 ºC. Standards compliance includes IEC, EN, UL, UNE, and VDE standards.

Current Detector Control Relay (WI)
Used for applications needing load control such as grinders, extrusion machines, and motors. Features include adjustable trip levels, automatic reset, and adjustable connection/disconnection times. Measurement options with built-in or separate transformers.

Harmonics Detector Control Relay (WDH)
Used to protect transformers and capacitor banks from harmonic overloads. Monitors and acts based on the true root mean square of harmonic current with adjustable trigger levels and delay times. Automatic reset with currents under 10% of the trip level.

Current Relay Station (CDR-8)
Measures and controls current for up to 8 lines, configurable as earth leakage or current relay. Displays current and status on an LCD, with programmable thresholds and delays. Includes features for automatic reclosing and remote signaling through RS-485.
