Terasaki Electric (Europe) Ltd. products

Air circuit breakers are critical components in ensuring the safety and protection of electrical installations. These devices are designed with a short-time withstand rating that matches their service breaking capacity, which guarantees optimal discrimination and selectivity. This feature allows for time-delayed short-circuit protection even at maximum prospective short-circuit currents. Key features include adjustable time-delayed overcurrent protection, short-circuit protection, and instantaneous protection, as well as adjustable time-delayed ground fault protection. These breakers are essential for increasing the reliability and lifespan of mission-critical installations by offering practical methods for safeguarding against faults. The advanced protection relay, AGR-31BR-PG, provides an LCD energy monitor with various adjustable curves such as standard inverse, very inverse, and extreme inverse, along with ground fault and fault indication contacts. These features make air circuit breakers indispensable for enhancing the endurance and protection of complex and vital electrical systems.

This product line features newly designed DIN modular Miniature Circuit Breakers (MCBs) which are engineered for enhanced safety and protection in electrical circuits. These circuit breakers feature dual connection terminals at the bottom for flexibility, accommodating both cable and busbar connections. They are offered with current ratings ranging from 0.5 to 123 amperes and fault current ratings up to 10 kA. Importantly, the 6 and 10 kA MCB ranges have been rigorously tested and certified by KEMA, ensuring reliable quality. The comprehensive range includes over 500 items, providing solutions suitable for a wide range of applications. Models such as the TD3 M06, TD3 M10, and others like TD31P1M and TD3 XA MCBs serve various needs including capacities below 125A. The range further includes other related items like TD3 ICP, TD3RCCB, TD3RCBO, and TD3 MS, with certain options like the red toggle feature for easy identification.

Terasaki, the exclusive distributor in the UK for low, medium, and high voltage power factor correction products, offers a comprehensive selection of modular cassettes and prefabricated freestanding capacitor banks designed for seamless integration into existing switchboards. These cassettes include self-healing three-phase PRT capacitors made of metalized polypropylene film, encased in a robust extruded aluminum shell with a steel disk seal to protect against environmental exposure. The capacitors feature an M12 x 12 mm fixing spigot for grounding, with a fiberglass-reinforced mount that supports the connection terminals. Safety is prioritized with an overpressure disconnecting device that halts power in case of overvoltage incidents. Installation is straightforward, with significantly reduced module widths to optimize switchboard size, and options for wall or free-standing units ranging from 20-500 KVAR. Terasaki's power factor regulators are equipped with up to 6 or 12 automatic cut-out steps, ensuring optimal performance and reliability.

Pro-DB Distribution Boards and Pro-Panel Panelboards are designed for Terasaki circuit breakers, offering co-ordinated protection from transformer to final circuit. These products will allow panelbuilders and installation contractors to offer systems which comply with UK building regulations and product standards.
