Product Introduction
ZYMM1-250L, this type of residual current circuit breakers RCCB is one of the most safest devices for detecting and preventing the tripping of leakage currents, thus ensuring protection against electric shocks caused by indirect contact. A residual current circuit breaker or RCCB is basically a gadget that induces current and the main purpose of installing a residual current circuit breaker is fundamentally to protect people from electric shock or death.
Yuming Electric’s residual current circuit breaker can be used to distribute electrical energy and to protect lines and power supply equipment from overloads and short circuits, also for infrequent line changes and infrequent motor starts.

Features & Benefits
A complete range of products and related accessories.
International mark certification for worldwide safety performance.
They can act as the main disconnect switch upstream of any derived MCB (e.g. home consumer unit).
Whenever a fault occurs, it disengages from any low voltage (unbalanced current) circuit.
FAQ
Q:What’s your products’s MOQ?
A:The MOQ differs among different products, for further information, please be free to contact us.We can accept low MOQ.
Q:Why RCCB is better than ELCB?
A:The RCCB is only connected to the phase and neutral wires. the ELCB only detects those electrical faults where leakage current flows through the main earth wire. the RCCB can detect any type of earth fault.
