Description
What it is
Three-pole medium voltage (15–36 kV class) circuit breaker from Siemens, with vacuum interruption. Switching and protection equipment designed to interrupt load and short-circuit currents in industrial networks, substations, and metal-clad switchgear.
Included accessories
Supplied with voltage transformer (VT), current transformer (CT), disconnect switch, surge arrester, allowing integrated measurement and protection in the same assembly.
Technology
Interruption in a vacuum chamber, with low maintenance, long electrical contact life, and gas-free — the most widely adopted technology in Brazilian industrial medium voltage.
Standards and safety
Designed according to ABNT NBR IEC 62271-100 (high/medium voltage circuit breakers), applicable in installations under NBR 14039 and NR-10.
