Established in 1998, China Dianshen Electric Co., Ltd. is a professional miniature circuit breaker manufacturer and mini circuit breaker design of electric and electronic products. Together with the European 'CE', 'CCC', GS/EMC/LICE/UL/CSA, and 'CB' (IEC) certification that we have received for various series. Currently, our custom miniature circuit breaker product series are being exported worldwide. Our pursuit of first-rate quality, competitive and cheap mini circuit breaker prices and comprehensive after-sales services offers both potential and long-standing clients confidence in our company.

CYD/C16 series miniature circuit breakers are composed case, operating mechanism,
contact system, arc-extinguishing system, tripping mechanism, etc. The caseis made of the soecial plastic high in fire-resistance and strength, so it is very capable of resisting impact and light in weight. The parts of the openratingmechanism employ high strength plastic products in order to assure the flexible,reliable operation and obtain the minimum moment of the tripping mechanism is very little. The tripping mechanism and short-circuit instantancous electromagneticmechanism. The contact arc-extinguishing system cmpoys the special arc conducting angle and gangway arc-extinguishing chamber so it has distinct current timiting characteristics.

Techna's JtecUL product provides a full range of Miniature Circuit Breakers, UL recognised to UL 1077. Additionally, JtecUL is UL listed as a manual motor controller to standard 508 for industrial control equipment and is suitable for motor disconnect. Available in trip curves B (quick), C (medium) and D (long delay) in current ratings from 0.5 to 63A, and all available in 1, 2, 3 or 4 poles, JtecUL 10kA MCBs offer maximum performance at excellent prices.
Most MCB's are only recognised to UL1077 which is a standard for supplementary protectors only. JtecUL goes further in that it is also listed to UL508. This rates JtecUL as suitable for use as a manual motor controller rated for motor disconnect. In simple terms you can replace the usual combination of disconnect switch, manual motor controller and a 1077 only breaker with our single JtecUL component. UL508 listed Jtec is suitable for use in control panels without further UL investigation. JtecUL has superior circuit protection ratings across the entire range. Many of our competitors only offer the full breaking capacity (interrupt rating) at 230Vac (instead of 277V) and sometimes only for a limited range of current ratings. JtecUL also meets European standard EN60898 for circuit breakers and is CE marked, ideal for manufacturers seeking to export their completed products into Europe.
