DWB Circuit Breakers: (Overview & Key Features)
Compact and Flexible Design
- The DWB series is built to save panel space with compact frames offering rated currents from 15 A up to 600 A, depending on the model—spanning DWB250, DWB400 and DWB600.
- Internal accessories (e.g. auxiliary contacts, shunt or undervoltage releases) are modular and user-installable, allowing flexibility across multiple frame sizes—especially 160, 250, 400, and 600.
Protection & Trip Units
-
Models offer both fixed and adjustable trip unit options. Common trip types include:
- DX: Fixed thermal + fixed magnetic
- GA/GF/MF/MA: Generator or motor applications with adjustable trips
- ET: For distribution/generator protection with electronic trip capabilities .
- For UL-listed units, such as DWB160, breakers are available in Standard (80% rated, “E”) and Premium (100% rated, “H”) configurations .
High Short-Circuit Interrupting Capacity
-
The DWB line is built for high performance:
- Some models feature interrupting capacities up to 80 kA at 380/415 V .
- For the DWB100 series (80% rated), typical ratings are around 14 kA at 480 V (UL).
- Premium (100% rated) versions maintain similar interrupting capacities.
Enhanced Safety & Accessibility
- A transparent front cover allows quick inspection of internal accessories, aiding safety and maintenance.
- Double insulation ensures live parts are isolated from the breaker’s front face (except terminals), reducing touch hazards.
