Miniature residual current circuit breaker with dual terminals

Double-terminal disconnect switch

It consists of three main components: an insulating housing, an operating mechanism, and a contact system. The insulating housing is injection-molded from high-strength, flame-retardant nylon; the contacts feature a bridge-type double-break design; and the operating mechanism is a spring‑energized, fast‑acting type. A dual-terminal design enhances wiring reliability. The product boasts a compact, aesthetically pleasing appearance, with a position‑indicating window, rapid breaking action, and sensitive, reliable operation. Equipped with upper and lower snap‑locks plus a two‑stage limiting latch, it is compatible with standard mounting rails for easy installation and removal. It supports any combination of 1P, 2P, 3P, or 4P configurations and can be used in conjunction with miniature circuit breakers and residual current circuit breakers, making it suitable for industrial, commercial, high‑rise, and residential applications.

Three-phase independent disconnect measurement switch

Suitable for 3-phase low-voltage distribution systems operating at AC 400 V/50 Hz, featuring independent tripping of all three phases and non‑forced interlocking of the remaining two phases in the event of a single‑phase fault. Integrates a Class 0.5S meter for measuring phase‑specific voltage, current, power, power factor, frequency, and electrical energy; provides comprehensive protection against overload, short circuit, phase loss, over‑/under‑voltage, and terminal temperature rise, along with fault event logging and reporting; supports remote measurement, signaling, control, and adjustment, including remote switching functions; compatible with HPLC, RS‑485, and Bluetooth communications, and compliant with DL/T 645 and DL/T 698.45 standards; housed in a flame‑retardant enclosure.
