Meba rccb and mcb MBL1210C

Meba rccb and mcb MBL1210C

Specification

Meba rccb and mcb MBL1210C

has introduced the F200 Ground Fault Equipment Protector (GFEP), designed to protect equipment against damaging line-to-ground currents by disconnecting all ungrounded conductors of the faulted circuit. A ground fault is caused by an insulation loss between a live conductor and an exposed conductive part that creates a flow of current to the ground. Most short circuits initially manifest as ground faults, which, if undetected, can cause serious and costly damage to electrical systems and equipment. An  F200 GFEP added to an electrical system trips when the system leaks a significant current to ground, immediately preventing the potential short circuit before such damage can occur.

The MEBA F200 GFEP line consists of the 2-pole F202 for single phase networks, and the 4-pole F204 for split phases, Delta and Wye networks.  The F200 GFEP immediately detects ground faults by continuously measures the current balance between live conductors and the neutral using a toroidal current transformer.

Application：

1. MBL1210C, Residual Current Devices for earth leakage detection.

2. It is to be used in association with miniature circuit breakers, its function is to detect earth leakage current and open the connected circuit to protect people and equipment, major used in industrial application.
