SCVS Series Molded Case Circuit Breaker (MCCB) Product Description
The SCVS series molded case circuit breakers are advanced electrical protection devices designed for AC circuits with frequencies of 50/60 Hz. Featuring a rated operational voltage of up to 690V AC and a rated current range from 16A to 630A, this series is ideal for industrial, commercial, and residential applications. It provides reliable electrical energy distribution while effectively safeguarding circuits against overload, short-circuit, and undervoltage faults. Additionally, it supports infrequent switching operations and is capable of motor protection tasks in diverse environments.
Compact and Robust Design:
Space-saving structure for efficient integration into switchboards.
Constructed with durable materials to ensure long-term reliable operation in harsh environments.
High Performance and Safety:
Short arcing distance design significantly reduces arc fault risks.
Large contact gap enhances insulation performance and service life.
Compliance and Versatility:
Complies with international standards IEC 60947-2 and UL 489.Compatible with thermal-magnetic trip units.
Available in 2P (two-pole), 3P (three-pole), and 4P (four-pole) configurations.
Operating Environment Requirements
To ensure optimal performance and safety, adhere to the following conditions:
Altitude:Maximum installation altitude of 2000 meters above sea level (consult the manufacturer for higher altitudes).
