T-Series Miniature Circuit Breakers are specifically designed for terminal power distribution protection in commercial office buildings, residential premises, and general industrial applications. Featuring overload and short-circuit protection, they can also be used for infrequent line switching operations under normal conditions.

With varying breaking capacities from 6kA to 15kA, our MCB range ensures reliable circuit protection for diverse applications while incorporating finger-safe combination terminals and providing clear contact status indication for enhanced operational safety.

T-Series RCBO devices combine the functionality of an RCCB (residual current protection) with an MCB (overcurrent protection) in a single compact unit. This integrated approach provides comprehensive protection against earth leakage faults, overloads, and short-circuits, enhancing electrical safety while saving space in distribution boards.

Our RCBO range offers various configurations to meet different application requirements, including different residual current sensitivities, breaking capacities, and current ratings. They are designed for reliable operation in residential, commercial, and industrial environments.

T-Series AFDD (Arc Fault Detection Device) is engineered to detect and mitigate hazardous series and parallel arc faults that conventional circuit breakers cannot identify. By detecting these dangerous faults that can lead to electrical fires, AFDDs provide an additional layer of protection for your electrical installations.

Our AFDD offers reliable arc fault protection along with overcurrent and short-circuit protection or residual current protection in a compact unit, making it ideal for high-risk residential buildings, multi-occupancy housing, student accommodation, care homes, and other locations requiring enhanced electrical safety.

T-Series Residual Current Circuit Breakers (RCCBs) offer reliable protection against electrical leakage currents, significantly reducing the risk of electric shock caused by indirect contact. Our RCCBs continuously monitor the balance of current flowing through the live and neutral conductors, and when an imbalance is detected (indicating current leaking to earth), they quickly disconnect the circuit.

Designed for versatility, our RCCB range supports both single-phase (240V, 1P+N) and three-phase (415V, 3P+N) power systems, with rated current capacities of up to 63A. This ensures dependable performance across a wide range of applications in residential, commercial, and industrial environments.

T-Series Isolator Switches are designed for reliable manual disconnection and isolation of main circuits in low-voltage distribution systems. Compliant with IEC/EN 60947-3, they are capable of making, carrying and breaking current under normal circuit conditions while maintaining short-circuit withstand capability for specified durations.

With rated currents up to 125A and configurations from 1P to 4P, the ETD1-125 family provides panel builders, OEMs, system integrators and electrical contractors with robust solutions for use as main switches in consumer units, distribution boards and compact enclosures. Multiple terminal options ensure compatibility with diverse installation requirements across all segments of the electrical market.

ETEK offers a growing portfolio of complementary T-Series modular devices to complete your electrical distribution system. These devices are designed with the same attention to quality, reliability and safety as our circuit protection products and feature compatible dimensions and aesthetics for seamless integration in distribution boards and consumer units.

From modular contactors and impulse relays for lighting and load control, to an expanding range of modular measuring, indication and voltage protection devices, our complementary products are designed to help you build complete, coordinated and dependable electrical systems tailored to your project requirements.
