Product Description

General

YCM8 Series circuit breakers are developed according to domestic and international market demand, as well as similar products.

Its rated insulation voltage is up to 1000V, suitable for AC 50Hz distribution network circuit whose rated operation voltage is up to 690V, rated operation current from 10A to 1250A. It can distribute power, protect the circuit and power supply devices from the damage of overload, short circuit and under voltage, etc.

This series of circuit breaker is featured as high breaking capacity and short arcing.
It can be installed vertically (namely vertical installation) and also installed horizontally (namely horizontal installation).

Standards: IEC60947-2.

Feature

Limiting the rise of short circuit current of circuit. The peak short circuit current and I2t power are much lower than the value expected.

Feature 1: Current limiting ability

The U shape fixed contact design achieves the technique of pre-breaking:

When the short circuit current goes through the contact system, there are forces that repel each other on the fixed contact and moving contact. The forces are produced with short circuit current and will enlarge synchronously when short circuit current

enlarges.

They elongate the electric arcing to enlarge their equivalent resistance to limit the rise of short circuit current.
